Dog

Trinomial name
Canis lupus familiaris
(Linnaeus, 1758)

The dog is a canine mammal of the Order Carnivora. Dogs were first domesticated from wolves at least 15000 years ago[1] but perhaps as long as 150,000 years ago based on recent genetic fossil evidence and DNA evidence[2]. In this time, the dog has developed into hundreds of breeds with a great degree of variation. For example, heights at the withers range from just a few inches (such as the Chihuahua) to roughly three feet (such as the Irish Wolfhound), and colors range from white to black, with reds, grays (usually called blue), and browns occurring in a tremendous variation of patterns.

Dogs, like humans, are highly social animals and pack hunters; this similarity in their overall behavioral pattern accounts for their trainability, playfulness, and ability to fit into human households and social situations. Dogs fill a variety of roles in human society and are often trained as working dogs. For dogs that do not have traditional jobs, a wide range of dog sports provide the opportunity to exhibit their natural skills. In many countries, the most common and perhaps most important role of dogs is as companions. Dogs have lived with and worked with humans in so many roles that their loyalty has earned them the sobriquet "man's best friend." Conversely, some cultures consider dogs to be unclean. In other cultures, some dogs are used as food.

Terminology

Puppies engage in teething on almost anything.

Dog, in common usage, refers to the domestic pet dog, Canis lupus familiaris (originally classified as Canis familiaris by Linnaeus in 1758, but reclassified as a subspecies of the wolf, Canis lupus, by the Smithsonian Institution and the American Society of Mammalogists in 1993). The word is sometimes used to refer collectively to any mammal belonging to the family Canidae (as in "the dog family"), such as wolves, foxes and coyotes.

Many additional terms are used for dogs that are not purebred; see Terms for mixed-breed dogs.

Physical characteristics

Although selective breeding has changed the appearance of many breeds, all dogs retain the basic ingredients from their distant ancestors. Like most other predatory mammals, the dog has powerful muscles, a cardiovascular system that supports both sprinting and endurance, and teeth for catching, holding, and tearing. Its skeleton provides the ability to run and leap. They have small, tight feet, and walk on their toes.

Intelligence

Among dog lovers, dogs are generally valued for their intelligence. Anecdotal evidence suggests that dogs have a reasonably high intelligence. For a detailed discussion on what dog intelligence is, see dog intelligence.

Diet

A fellow editor requested that someone provide references or sources for the information in this section. This English Springer Spaniel is enjoying a bone.

Presently, there is academic discussion as to whether domestic dogs are omnivores or carnivores. The classification in the Order Carnivora does not necessarily mean that a dog's diet must be restricted to meat. Unlike an obligate carnivore, such as a cat, a dog is not dependent on meat protein in order to fulfill its dietary requirements. Dogs are able to healthily digest a variety of foods including vegetables and grains, and in fact can consume a large proportion of these in their diet. Wild canines not only eat available plants to obtain key amino acids, but may also obtain nutrients from vegetable matter from the stomach contents of their herbivorous prey. Domestic dogs can survive healthily on a reasonable and carefully designed vegetarian diet, particularly if eggs and milk products are included. Some sources suggest that a dog fed on a stict vegetarian diet may develop dilated cardiomyopathy since it lacks L-carnitine.[3]

In the wild these diets are typically pursued in the absence of available meat. It has also been noted that extremely stressful conditions, such as the Iditarod race and scientific studies of similar conditions, suggest that high-protein diets including meat help prevent damage to muscle tissue. This research is also true of other mammals.

Dogs sometimes eat grass, a harmless activity. Explanations abound, but rationales such as that it neutralizes acid are just guesses. Eating grass might make the dog vomit, so one explanation is that dogs eat grass to remove unwanted content from their stomachs.

Treats

Many dogs consider anything given to them directly by hand to be a treat, even the food they are accustomed to at meal time. Such dogs might consider anything dropped by humans, including small but indigestible objects (such as marbles, coins, rings, etc.), to be treats as well, which could be dangerous to the dogs when ingested.

For a discussion on one use of treats in training, see clicker training.

Dangerous substances

Some foods commonly enjoyed by humans are dangerous to dogs, including chocolate (Theobromine poisoning), onions, grapes and raisins, Macadamia nuts, and hops. Some human medications, such as acetaminophen/paracetamol (Tylenol), are highly toxic to dogs. Alcoholic beverages pose much the same temptation and hazard to dogs as to humans. Dogs also may find some poisons attractive, including antifreeze and snail bait.

Reproduction

Among professional breeders, dogs are only allowed to mate for a specific purpose. Sometimes dogs are bred to create puppies to sell, or sometimes to carry on an award-winning purebred line. Breeders who do this are usually experienced in this process. Dog breeders have access to records which allow them to accurately guess which characteristics will "breed true" in a particular dog. Dog breeders also have accurate information on the complexities of the reproductive process for the breed of dog that they are accustomed to handling. Dog owners may accidentally allow their pets to breed without regard to bloodlines.

Fertility

As with most domesticated species, one of the first and strongest effects seen from selective breeding is selection for cooperation with the breeding process as directed by humans. In domestic dogs, one of the behaviours that is noted is the abolition of the pair bond seen in wild canines. The ability of female domestic dog to come into estrus at any time of the year and usually twice a year is also valued. The amount of time between cycles varies greatly among different dogs, but a particular dog's cycle tends to be consistent through her life. This is also called in season or in heat. Conversely, undomesticated canine species experience estrus once a year, typically in late winter.

Menarche

Most bitches come into season for the first time between 6 and 12 months, although some larger breeds delay until as late as 2 years. Like most mammals, the age that a bitch first comes into season is mostly a function of her current body weight as a proportion of her body weight when fully mature. The different rates of maturation are responsible for the menarche, not the chronological age.

Pregnancy and litters

A general rule of thumb is that a mammal will produce half as many offspring as the number of teats on the mother. This rule is altered in domesticated animals since larger litters are often favoured for economic reasons. Dogs bear their litters roughly 9 weeks after fertilization. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. Since a mother can only provide nutrients and care to a limited number of offspring, humans must assist in the care and feeding when the litter exceeds approximately eight puppies. Some breeds have been developed to emphasize certain physical traits beyond the point at which they can safely bear litters on their own. For example, the Bulldog often requires artificial insemination and almost always requires cesarean section for giving birth.

Spaying and neutering

Spaying or neutering refers to the removal of the male testicles or the female ovaries and uterus, in order to remove the capability to procreate, and to kill the libido.

Dog experts advise that dogs not intended for further breeding should be spayed or neutered so that they do not have undesired puppies. Unwanted puppies are abandoned, eaten, or sometimes disposed of in an inhumane fashion. It is also common for adult stray dogs who are placed in animal shelters to be euthanized due to lack of space and resources.

Spaying and neutering can also help prevent hormone-driven diseases such as breast cancer and prostate cancer, as well as undesired hormone-driven behaviors. The hormonal changes involved are sure to change the animal's personality somewhat, and some object to this angle as the sterilization in itself could be carried out without the excision of organs.

Contrary to myth, it is not required for a female dog to either experience a heat cycle or have puppies before spaying, and likewise, a male dog does not need the experience of mating before neutering; these myths are responsible for numerous unnecessary health problems and unwanted puppies. A female dog can become pregnant on her first heat cycle (which can take place as early as six months), and should be kept away from intact male dogs, including littermates, over the age of 4 months. Many veterinarians recommend that owners neuter/spay their pets around the age of 5 months.

Attributes

Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Within the range of extremes, dogs generally share attributes with their wild ancestors, the wolves. Dogs are predators and scavengers, possessing sharp teeth and strong jaws for attacking, holding, and tearing their food.

Sight

Dogs were thought to be dichromats and thus, by human standards, color blind.1, 2 New research is now being explored that suggests that dogs may actually see some colour, but not to the extent that humans do. It has also been suggested that dogs see in varieties of purple/violet and yellow shades. Because the lenses of dogs' eyes are flatter than humans', they cannot see as much detail; on the other hand, their eyes are more sensitive to light and motion than humans' eyes. Some breeds, particularly the best sighthounds, have a field of vision up to 270° (compared to 100° to 120° for humans), although broad-headed breeds with their eyes set forward have a much narrower field of vision, as low as 180°.1, 2

Hearing

Dogs detect sounds as low as the 16 to 20 Hz frequency range (compared to 20 to 70 Hz for humans) and as high as 70,000 to 100,000 Hz (compared to 20,000 Hz for humans)2, and in addition have a degree of ear mobility that helps them to rapidly pinpoint the exact location of a sound. They can identify a sound's location much faster than a human can, and they can hear sounds up to four times the distance that humans can.

Scenting

Dogs are predators suited to chasing after, leaping at, and killing prey. (pictured: Weimaraner)

Dogs have nearly 220 million smell-sensitive cells over an area about the size of a pocket handkerchief (compared to 5 million over an area the size of a postage stamp for humans). Some breeds have been selectively bred for excellence in detecting scents, even compared to their canine brethren. What information a dog actually detects when he is scenting is not perfectly understood; although once a matter of debate, it now seems to be well established that dogs can distinguish two different types of scents when trailing, an air scent from some person or thing that has recently passed by, as well as a ground scent that remains detectable for a much longer period. The characteristics and behavior of these two types of scent trail would seem, after some thought, to be quite different, the air scent being intermittent but perhaps less obscured by competing scents, whereas the ground scent would be relatively permanent with respect to careful and repetitive search by the dog, but would seem to be much more contaminated with other scents. In any event, it is established by those who train tracking dogs that it is impossible to teach the dog how to track any better than it does naturally; the object instead is to motivate it properly, and teach it to maintain focus on a single track and ignore any others that might otherwise seem of greater interest to an untrained dog. An intensive search for a scent, for instance searching a ship for contraband, can actually be very fatiguing for a dog, and the dog must be motivated to continue this hard work for a long period of time.

Direction and spatial sense

It has been observed that a lost dog can often find its way home, sometimes traveling over long distances.

Weather detection

Dogs also have the ability to sense inclement weather (mainly thunderstorms) many miles away. This is due to their keen ability to detect fluctuations in barometric pressure and can explain a dog's anxiety before and during a storm. The evolutionary ability of sensing weather can be traced back to when wolves used it to move the pack into proper shelter before a dangerous storm. For example, during the tsunami in Southern Asia recently, many animals were seen days before fleeing to the hills. It is said that the animals, not just dogs, could sense the tsunami and could therefore flee for life.

Dog health

Further information: Category:Dog health

Dogs are susceptible to various diseases, ailments, and poisons, some of which affect humans in the same way, others of which are unique to dogs.

Diseases

Diseases commonly associated with dogs include rabies (hydrophobia), canine parvovirus, and canine distemper, and pulmonic stenosis, although there are many others.

Parasites

Common external parasites are various species of fleas, ticks, and mites. Internal parasites include hookworms, tapeworms, roundworms, and heartworms.

Common physical disorders

Some breeds of dogs are also prone to certain genetic ailments, such as hip dysplasia, luxating patellas, cleft palate, blindness, or deafness. Dogs are also susceptible to the same ailments that humans are, including diabetes, epilepsy, cancer, and arthritis. Gastric torsion and bloat is a dangerous problem in some large-chested breeds.

Behavior

Some dogs can be trained to retrieve

All dogs have a tremendous capacity to learn complex social behavior and to interpret varied body language and sounds, and, like many predators, can react to and learn from novel situations. The requirements of coordinating complex social behavior requires that canines have the ability to sense and deliver a wide variety of cues via body language, more so than for even humans, who can use language for the same purpose. Physiologically, this correlates with such features as a large number of nerves innervating the facial muscles of dogs, allowing subtle control of a wide variety of facial expressions; in contrast to cats, for instance, who have many fewer nerves governing their facial muscles, resulting in a smaller repertoire or "vocabulary" of expressions. This ability to read and deliver nonverbal cues makes dogs expert at reading human beings, as well, often even more so than other humans are, who rely on language. Most dog owners have a large collection of stories about their dogs recognizing individuals by their footsteps outside the door, and so on.

Interactions between Dogs and Humans

The relationship between dogs and humans is rooted in history and dogs coexist with humans in a variety of ways. Dogs thrive in small social groups or packs which, from their viewpoint, can include humans. Dog society can be thought of as dog packs characterized by a companionate hierarchy, in which each individual has a rank, and in which there is intense loyalty within the group. Dogs thrive in human society because their relationships with humans mimic their natural social patterns. The dog is always aware of its rank relative to other individuals in the group. An assertive dog may consider itself the alpha animal, considering its human master to be subordinate.

Dogs as working partners

Many breeds of dogs, but not least German Shepherd, Labrador Retriever, and Border Collie are commonly used as working dogs. There are service dogs, guard dogs, hunting dogs, and herding dogs. Dogs have served as guides for the blind, as commandos, and have flown into outer space. Most modern working dogs are put in positions which capitalize on their sensory or strength and endurance advantages over normal humans. Dogs are also used for searching for or rescuing people and animals, such as in avalanches, at disaster sites, and for missing people or pets.

Dogs as hunting and sporting partners

Many people compete with their dogs in a variety of dog sports, including agility, flyball, and many others. This often strengthens the bond between human and dog, since they must trust one another in a variety of environments and must learn how the other works and thinks.

Setters in particular have a long history as upland gun dogs. They have a native ability to discover and "hold" upland game birds; to freeze them momentarily on the ground with their silent, elongated pointing stance. Once the hunter approaches, at his command they will flush the birds to fly and for the hunter to shoot at.

As water dogs, the retrievers are unsurpassed. They can spend long hours in a duck blind and, after the hunter has fired at multiple ducks or geese, they can visually spot and remember the location of downed birds. At command, they dive into the icy water, swim out and retrieve the birds one by one. They can follow hand, verbal, and whistle commands at great distance as the hunter directs them to the downed bird. They typically have large, gentle muzzles to mitigate any potential damage to the game.

When trained, beagles are particularly adept at chasing through thick briars and brush after rabbits. Many hound breeds are excellent at treeing raccoons during hunting season.

Hunters with dogs report the satisfaction that the dogs seem to exhibit. Excitement is evident as they see the hunters load weapons, take to the field, and begin the hunt.

Dogs as pets

Relationships between humans and dogs are often characterized by strong emotional bonds. Consequently, dogs are popular as pets and companions, independent of any utilitarian considerations. Many dog owners consider having unconditional acceptance from a friend who is always happy to see them to be quite utilitarian, particularly if the dog also leads them to regular exercise. Empirically, dogs are quite dependent on human companionship and may suffer poor health in its absence. Many dogs are reported to have separation anxiety if their owner is away for an extended period of time.

Some research demonstrates that dogs are able to convey a depth of emotion not seen to the same extent in any other animal; this is purportedly due to their closely-knit development with modern man, and the survival-benefits of such communication as dogs became more dependent on humans for sustenance.

Nevertheless, it is often unwise to anthropomorphize the responses of dogs. Despite understandably positive interpretations by dog owners, it is questionable whether these animals are truly capable of feeling emotions on a human level. More research is needed to determine the intelligence level of dogs, and the motivations behind their responses to their masters.

Attacks on humans and livestock

Humans have a tendency to anthropomorphize animals, particularly pets such as dogs, which are generally portrayed as being "man's best friend". Animals are often given attributes such as "loyal", "cute", and "guardian", but these all have the potential to lure people into a false sense of security.

After thousands of years of domestication and selective breeding for dogs whose aggression towards humans goes no further than a ferocious bark that strongly indicates dislike of a human behavior, most dogs are unlikely to attack people. However, their sharp teeth and claws can inflict injury in an attack; a large dog can knock a human down. Provocation can range from something as seemingly innocuous as a toddler pulling a dog's tail, in which case the dog might nip to discourage the behavior, to something completely inobvious to humans, such as an odor or a movement that sets a dog off, to blatant human aggression or violence towards a dog, causing it to defend itself. There are hundreds of shades of provocation that may or may not lead to an attack upon a human. Canine aggression upon humans is ordinarily not tolerated, but any human aggression against an animal having formidable means of self-defense is foolhardy in the extreme.

With formidable skills and weapons as hunters as well as large and unfussy appetites, dogs often menace livestock and wildlife. In most jurisdictions, dogs are destroyed for killing other creatures, so dogs should be prevented from any encounter with livestock or wildlife that might lead to a predatory response. The same creatures that wolves, coyotes, and foxes attack as prey, especially sheep and poultry, are similarly attractive prey to dogs.

Abandoned dogs

Wild dogs are shot by farmers in an effort to protect livestock. Bodies are sometimes tied to fences as warning to other dogs, especially in rural United States and Canada. Abandoned domestic dogs who become feral are particularly dangerous; they lack the survival skills of wild canines, as well as the genetic and learned fear of the humans' world. Feral dogs often form predatory packs that attack livestock and occasionally also prove dangerous to humans.

In the UK, it is illegal to kill dogs, even if they are on your private land; you are required to contact your local Police Force, DogsTrust, or the local branch of the RSPCA, who will arrange its collection.

Ancestry and history of domestication

This ancient mosaic, likely Roman, shows a large dog with a collar hunting a lion.

Molecular systematics indicate that the domestic dog (Canis lupus familiaris) descends from one or more populations of wild wolves (Canis lupus). As reflected in the nomenclature, dogs are a subspecies of wolf and are thus still able to interbreed.

The relationship between man and canine has deep roots. Wolf remains have been found in association with hominid remains dating from 400,000 years ago. Converging archaeological and genetic evidence indicate a time of domestication in the late Upper Paleolithic close to the Pleistocene/Holocene boundary, between 17,000 and 14,000 years ago. Fossil bone morphologies and genetic analysis of current and ancient dog and wolf populations have not yet been able to conclusively determine whether all dogs descend from a single domestication event, or whether dogs were domesticated independently in more than one location. Domesticated dogs may have interbred with local populations of wild wolves on several occasions (so-called introgression).

The earliest dog fossils, two crania from Russia and a mandible from Germany, date from 13,000 to 17,000 years ago. Their likely ancestor is the large northern Holarctic wolf, Canis lupus lupus. Remains of smaller dogs from Mesolithic (Natufian) cave deposits in the Middle East, dated to around 12,000 years ago, have been interpreted as descendants of a lighter Southwest Asian wolf, Canis lupus arabs. Rock art and skeletal remains indicate that by 14,000 years ago, dogs were present from North Africa across Eurasia to North America. Dog burials at the Mesolithic cemetery of Svaerdborg in Denmark suggest that in ancient Europe dogs were valued companions.

Genetic analyses have so far yielded divergent results. Vilà, Savolainen, and colleagues (1997) concluded that dogs split off from wolves between 75,000 and 135,000 years ago, while a subsequent analysis by Savolainen et al. (2002) indicated a "common origin from a single gene pool for all dog populations" between 40,000 and 15,000 years ago in East Asia. Verginelli et al. (2005), however, suggest both sets of dates must be reevaluated in light of recent findings showing that poorly calibrated molecular clocks have systematically overestimated the age of geologically recent events. On balance, and in agreement with the archaeological evidence, 15,000 years ago is the most likely time for the wolf-dog divergence.

Verginelli examined ancient DNA evidence from five prehistoric Italian canids carbon-dated to between 15,000 and 3,000 years old, 341 wolves from several populations worldwide, and 547 purebred dogs. Their results indicate multiple independent origins of dogs and/or of frequent interbreeding between early proto-dogs and wolves throughout a vast geographic range. The detailed history remains unexplored and until further evidence is available, the following section on wolf ancestors must be considered purely speculative.

Wolf ancestors

Although all wolves belong to the species Canis lupus, there are (or were) many subspecies that had developed a distinctive appearance, social structure, and other traits. For example, the Japanese wolf and the Eastern Timber Wolf posses different distinctive colouration, hunting and social structures.

The Indian Wolf is thought to have contributed to the development of more breeds of dogs than other subspecies. Many of today's wild dogs, such as the dingo, the dhole and pariah dogs, are descended from this wolf.

The Indian wolf is also thought to have bred with descendants of the European wolf to create the Mastiffs and eventually leading to the development of such diverse breeds as the Pug, the Saint Bernard, and the Bloodhound. The Tibetan Mastiff is an example of an ancient breed.

The European wolf, in turn, may have contributed many of its attributes to the Spitz dog types, most terriers, and many of today's sheepdogs. The Chinese wolf is probably ancestor to the Pekingese and toy spaniels, although it is also probable that descendants of the Chinese and European wolves encountered each other over the millennia, contributing to many of the oriental toy breeds.

The Eastern Timber Wolf is a direct ancestor to most, if not all, of the North American northern sled dog types. This interbreeding still occurs with dogs living in the Arctic region, where the attributes of the wolf that enable survival in a hostile environment are valued by humans. Additionally, unintentional crossbreeding occurs simply because dogs and wolves live in the same environment. The general reproductive isolation which is required to define dogs and wolves as separate species is purely a result of lack of opportunity, stemming from a general mutual unfamiliarity, suspicion, mistrust, and fear.

The phenotypic characteristic that distinguish a wolf from a dog are tenuous. Wolves typically have a "brush tail" and erect ears. While some dog breeds possess one of these characteristics, they rarely possess both.

Speed of domestication

Current research indicates that domestication, or the attributes of a domesticated animal, can occur much more quickly than previously believed. Domestication of a wild dog may occur within one or two human generations with deliberate selective breeding. It is also now generally believed that initial domestication was through mutual desire. Wild canines who scavenged around human habitations received more food than their more skittish or fearful counterparts. Canines who attacked people or their children were likely killed or driven away, while those more friendly animals survived. Canines would have been beneficial by chasing away other vermin or scavengers. With their sharp senses, they would also be valuable as an alarm against marauding predators. The relationship is theorized to have developed in this way.

Dogs as food

In a number of countries around the world, apart from being kept as pets, certain breeds of dogs are slaughtered as a source of meat and specifically raised on farms for that purpose.

Dog breeds

There are numerous dog breeds, over 800 being recognized by various kennel clubs worldwide. As all dog breeds have been derived from mixed-breed dog populations, the term "purebred" has meaning only with respect to a certain number of generations. Many dogs, especially outside the United States and Western Europe, belong to no recognized breed.

A few basic breed types have evolved gradually during the domesticated dog's relationship with man over the last 10,000 or more years, but most modern breeds are of relatively recent derivation. Many of these are the product of a deliberate process of artificial selection. Because of this, some breeds are highly specialized, and there is extraordinary morphological diversity across different breeds. Despite these differences, dogs are able to distinguish dogs from other kinds of animal.

The definition of a dog breed is a matter of some controversy. Some groups use a definition that ultimately requires extreme inbreeding to qualify due to the low gene pool. Dogs that are bred in this manner often end up with severe health or behavioural problems. Other organizations define a breed more loosely, such that an individual may be considered of one breed as long as 75% of its parentage is of that breed. These considerations come into play among breeders who enter their dogs in dog shows. Even prize-winning purebred dogs sometimes possess crippling genetic defects due to inbreeding. These problems are not limited to purebred dogs and can affect mixed-breed populations. The behavior and appearance of a dog of a particular breed can be predicted fairly accurately, while mixed-breed dogs show a broader range of innovative appearance and behavior.

In February 2004, the Canine Studies Institute in Aurora, Ohio, arranged recognized breeds of dogs into ten categories.

Mixed-breed dogs or Mongrels are dogs that do not belong to specific breeds, being mixtures of two or more in variant percentages. Mixed breeds, or dogs with no purebred ancestry, are not inherently "better" or "worse" than purebred dogs as companions, pets, working dogs, or competitors in dog sports. Sometimes mixed-breed dogs are deliberately bred, for example, the Cockapoo, a mixture of Cocker Spaniel and Miniature Poodle. Such deliberate crosses may display hybrid vigor and other desirable traits, but can also lack one or more of the desired traits of their parents, such as temperament or a particular color or coat. However, without genetic testing of the parents, the crosses can sometimes end up inheriting genetic defects that occur in both parental breeds. Deliberately crossing two or more breeds is also a manner of establishing new breeds.

Neoteny in the rapid evolution of diverse dog breeds

This rapid evolution of dogs from wolves is an example of neoteny or paedomorphism. As with many species, the young wolves are more social and less dominant than adults; therefore, the selection for these characteristics, whether deliberate or inadvertent, is more likely to result in a simple retention of juvenile characteristics into adulthood than to generate a complex of independent new changes in behavior. This is true of many domesticated animals, including human beings themselves, who have many characteristics similar to young bonobo. This paedomorphic selection naturally results in a retention of juvenile physical characteristics as well. Compared to wolves, many adult dog breeds retain such juvenile characteristics as soft fuzzy fur, round torsos, large heads and eyes, ears that hang down rather than stand erect, etc.; characteristics which are shared by most juvenile mammals, and therefore generally elicit some degree of protective and nurturing behavior cross-species from most adult mammals, including humans, who term such characteristics "cute" or "appealing".

The example of canine neoteny goes even further, in that the various breeds are differently neotenized according to the type of behavior that was selected.

Of course, dogs in general possess a significant ability to modify their behavior according to experience, including adapting to the behavior of their "pack leaders"—again, humans. This allows them to be trained to behave in a way that is not specifically the most natural to their breed; nevertheless, the accumulated experience of thousands of years shows that some combinations of nature and nurture are quite daunting, for instance, training whippets to guard flocks of sheep.

This allows them to be trained to behave in a way that is not specifically the most natural to their breed; nevertheless, the accumulated experience of thousands of years shows that some combinations of nature and nurture are quite daunting, for instance, training whippets to guard flocks of sheep. Recently ICC choose Dubai as its new Headquarters leaving Lords which hosted ICC for 95 years. Of course, dogs in general possess a significant ability to modify their behavior according to experience, including adapting to the behavior of their "pack leaders"—again, humans. Dubai is fast gaining its name as international venue for sporting activities. The example of canine neoteny goes even further, in that the various breeds are differently neotenized according to the type of behavior that was selected. Dubai maintains cultural, economic and educational ties with Dundee, Scotland, Damascus, Detroit, Geneva, Istanbul, Osaka, Beirut, Shangai, Jarusalem, Casablanca, Guangzhou,. Compared to wolves, many adult dog breeds retain such juvenile characteristics as soft fuzzy fur, round torsos, large heads and eyes, ears that hang down rather than stand erect, etc.; characteristics which are shared by most juvenile mammals, and therefore generally elicit some degree of protective and nurturing behavior cross-species from most adult mammals, including humans, who term such characteristics "cute" or "appealing".

In common practice, an address consists of: street number, building number and community name although the order may very. This rapid evolution of dogs from wolves is an example of neoteny or paedomorphism. Addressing and location: The formal addressing system is: sector number, community number, street number and building number.

Deliberately crossing two or more breeds is also a manner of establishing new breeds. Note that these progressions are repeated within each community so, for example there will be numerous street number 5 along the Jumeirah 1, 2, 3, and Umm Suqeim 'strip'. However, without genetic testing of the parents, the crosses can sometimes end up inheriting genetic defects that occur in both parental breeds. Odd numbered street are perpendicular to the coast and increase as one moves away from the creek. Such deliberate crosses may display hybrid vigor and other desirable traits, but can also lack one or more of the desired traits of their parents, such as temperament or a particular color or coat. In general, even numbered streets run parallel to the coast and increase in number as one goes inland. Sometimes mixed-breed dogs are deliberately bred, for example, the Cockapoo, a mixture of Cocker Spaniel and Miniature Poodle. Within these communities are numbered streets and house/building numbers.

Mixed breeds, or dogs with no purebred ancestry, are not inherently "better" or "worse" than purebred dogs as companions, pets, working dogs, or competitors in dog sports. Communities:. Mixed-breed dogs or Mongrels are dogs that do not belong to specific breeds, being mixtures of two or more in variant percentages. Currently there are 44 communities. In February 2004, the Canine Studies Institute in Aurora, Ohio, arranged recognized breeds of dogs into ten categories. Each sector is sub-divided into communities of various size with major (named) roads as the bountries. The behavior and appearance of a dog of a particular breed can be predicted fairly accurately, while mixed-breed dogs show a broader range of innovative appearance and behavior. Dubai is divided into 9 sectors: 1-4 & 6 are urban; 7-9 are rural; 8 is Jebel Ali.

These problems are not limited to purebred dogs and can affect mixed-breed populations. Most contracts and tenancy agreements do not stand up to the standards of international law and almost always grossly favour the lessor or the company selling property. Even prize-winning purebred dogs sometimes possess crippling genetic defects due to inbreeding. Legislation in this area is still sketchy as the property market is a new one and rights of tenants and landowners are based on shaky principles borrowed mainly from European law. These considerations come into play among breeders who enter their dogs in dog shows. This cap demonstrates the realisation that uncontrolled rents can hamper development. Other organizations define a breed more loosely, such that an individual may be considered of one breed as long as 75% of its parentage is of that breed. Rents have also skyrocketed with the recent inflow of professionals and companies from around the world who are attracted by Dubai's no-tax benefits although rises have been capped to 15% per annum up to 2006 under a directive from Sheikh Mohammad.

Dogs that are bred in this manner often end up with severe health or behavioural problems. In Dubai, demand is currently outstripping supply by a significant margin and is showing no signs of slowing in the near future. Some groups use a definition that ultimately requires extreme inbreeding to qualify due to the low gene pool. The larger of the property tycoons are Al Nakheel and Emaar Properties. The definition of a dog breed is a matter of some controversy. One of the other reasons for the boom in construction is the recent reversal of a law in 2002 that allows non-nationals of the UAE to own property (not land) in Dubai (albeit freehold and 99 year leases are actually sold to people with ownership still remaining with private companies). Despite these differences, dogs are able to distinguish dogs from other kinds of animal. Tourism is also being promoted at a staggering rate with the construction of Dubailand and other projects that include the making of mammoth shopping malls, theme parks, resorts, stadiums and other various tourist attractions.

Because of this, some breeds are highly specialized, and there is extraordinary morphological diversity across different breeds. The Dubai government does not want to depend on its oil reserves which are largely believed to become exhausted by 2010 and, as such, has diversified its economy to attract revenues in the form of expanding commercial and corporate activity. Many of these are the product of a deliberate process of artificial selection. One of the main reasons for the boom in construction in Dubai is its drive to diversify the economy. A few basic breed types have evolved gradually during the domesticated dog's relationship with man over the last 10,000 or more years, but most modern breeds are of relatively recent derivation. This is partly due to the fact that labourers from the Indian subcontinent accept lower wages than those from other countries. Many dogs, especially outside the United States and Western Europe, belong to no recognized breed. Construction in Dubai and the UAE in general is a much faster process than in any Western country.

As all dog breeds have been derived from mixed-breed dog populations, the term "purebred" has meaning only with respect to a certain number of generations. In many areas, it is not easy to see Dubai's sky without at least one crane in your view; some say 16% of the world's large construction cranes would stand there. There are numerous dog breeds, over 800 being recognized by various kennel clubs worldwide. Since 2000, Dubai's municipality has initiated a plethora of construction phases and plans across the entire city of Dubai, predominantly in the Mina Seyahi area, located further from Jumeirah, towards Jebel Ali. In a number of countries around the world, apart from being kept as pets, certain breeds of dogs are slaughtered as a source of meat and specifically raised on farms for that purpose. In addition, Emirates has placed an order of 42 of the new Boeing 777 aircraft in November 2005. The relationship is theorized to have developed in this way. The A380 aircraft have already been charted to fly from October 2006 onwards.

With their sharp senses, they would also be valuable as an alarm against marauding predators. The airline has placed an order of 45 of Airbus's A-380 'superjumbo' doubledecker aircraft, the largest of which has a capacity of 641 passengers. Canines would have been beneficial by chasing away other vermin or scavengers. The idea is to develop Dubai's air transportation ability so that passengers from any city can fly direct to Dubai. Canines who attacked people or their children were likely killed or driven away, while those more friendly animals survived. Dubai is also investing heavily in developing the reach of its airline, Emirates. Wild canines who scavenged around human habitations received more food than their more skittish or fearful counterparts. Seven monorails are also slated to be constructed to help feed the Metro system, connecting various places such as Dubailand, Palm Jumeriah, et al, to the main track.

It is also now generally believed that initial domestication was through mutual desire. Dubai is building this train system to ease congestion on its road network and to meet the transportation demands of its growing population. Domestication of a wild dog may occur within one or two human generations with deliberate selective breeding. Trains are expected to run every 90 seconds when the project is completed. Current research indicates that domestication, or the attributes of a domesticated animal, can occur much more quickly than previously believed. The Dubai Metro will have 70 kilometers of track and 43 stations, 33 above ground and ten underground. While some dog breeds possess one of these characteristics, they rarely possess both. The metro will comprise two lines: the Green Line from Rashidiya to the main city center and the Red Line from the airport to Jebel Ali.

Wolves typically have a "brush tail" and erect ears. Also involved are two other Japanese corporations, Obayashi and Kajima, and a Turkish company, Yapi Merkezi. The phenotypic characteristic that distinguish a wolf from a dog are tenuous. The construction contract for the project was given to Dubai Rapid Link (DURL)[11], a consortium lead by Mitsubishi Heavy Industries. The general reproductive isolation which is required to define dogs and wolves as separate species is purely a result of lack of opportunity, stemming from a general mutual unfamiliarity, suspicion, mistrust, and fear. The Metro system is expected to be partially operational by 2009 and fully operational by 2012. Additionally, unintentional crossbreeding occurs simply because dogs and wolves live in the same environment. There is currently a $3.89 billion Dubai Metro project under construction for the emirate.

This interbreeding still occurs with dogs living in the Arctic region, where the attributes of the wolf that enable survival in a hostile environment are valued by humans. One of the more traditional methods of getting across Bur Dubai to Deira is through abras, small boats that ferry passengers across the Dubai creek, between abra stations in Bastakiya and Bani Yas Road, for a nominal charge of 1 Dh. The Eastern Timber Wolf is a direct ancestor to most, if not all, of the North American northern sled dog types. Cabs can be found anywhere, any time although difficulties may be experienced during large events. The Chinese wolf is probably ancestor to the Pekingese and toy spaniels, although it is also probable that descendants of the Chinese and European wolves encountered each other over the millennia, contributing to many of the oriental toy breeds. Taxi drivers will usually try to avert this happening in traffic queues by moving slightly forward every 30 seconds or so. The European wolf, in turn, may have contributed many of its attributes to the Spitz dog types, most terriers, and many of today's sheepdogs. 3, which is approximately 50pence, or 1 USD), and are charged by distance, although if the cab stops for more than 1 minute, 1/2 a Dirham will be added to the meter.

The Tibetan Mastiff is an example of an ancient breed. Prices are reasonable (the meter begins as Dhs. The Indian wolf is also thought to have bred with descendants of the European wolf to create the Mastiffs and eventually leading to the development of such diverse breeds as the Pug, the Saint Bernard, and the Bloodhound. Some of the private cab companies are Cars Taxi, National Taxi, Cititaxi and Metro Taxi. Many of today's wild dogs, such as the dingo, the dhole and pariah dogs, are descended from this wolf. The Dubai Transport Corporation operates cream-colored taxis. The Indian Wolf is thought to have contributed to the development of more breeds of dogs than other subspecies. There are both government-operated and private cab companies.

For example, the Japanese wolf and the Eastern Timber Wolf posses different distinctive colouration, hunting and social structures. Dubai also has an extensive taxi system, by far the most frequently used means of public transport within the emirate. Although all wolves belong to the species Canis lupus, there are (or were) many subspecies that had developed a distinctive appearance, social structure, and other traits. Due to the frequency of such incidents, road networks are blocked and held up quite frequently. The detailed history remains unexplored and until further evidence is available, the following section on wolf ancestors must be considered purely speculative. Furthermore, Dubai has developed a reputation for having the most number of deaths and road accidents in the developed world clocking in with a statistic of having a minor road accident at least every 3 minutes. Their results indicate multiple independent origins of dogs and/or of frequent interbreeding between early proto-dogs and wolves throughout a vast geographic range. Traffic congestion has come about mainly due to lack of foresight on the recent rapid population increase, the relative ease of credit facilities for obtaining a car and the convoluted road networks that are constantly being changed, improved or reconstructed.

Verginelli examined ancient DNA evidence from five prehistoric Italian canids carbon-dated to between 15,000 and 3,000 years old, 341 wolves from several populations worldwide, and 547 purebred dogs. Unfortunately though, the bus network is used extensively by lower income groups and does not do enough to attract higher income earners who would do well to use the bus transport system and ease traffic congestion that has recently become a major problem in Dubai and the United Arab Emirates. On balance, and in agreement with the archaeological evidence, 15,000 years ago is the most likely time for the wolf-dog divergence. There are also several discounts and period pass options available. (2005), however, suggest both sets of dates must be reevaluated in light of recent findings showing that poorly calibrated molecular clocks have systematically overestimated the age of geologically recent events. The government has issued plastic, swipable "e-go" cards. Verginelli et al. The bus system has 59 unique routes on weekdays and transports over 200,000 people each week.

(2002) indicated a "common origin from a single gene pool for all dog populations" between 40,000 and 15,000 years ago in East Asia. Dubai has a fairly large bus system run by the Dubai Municipality. Vilà, Savolainen, and colleagues (1997) concluded that dogs split off from wolves between 75,000 and 135,000 years ago, while a subsequent analysis by Savolainen et al. Although initially intended as a predominantly cargo airport, plans are afoot for the new Jebel Ali airport to handle some 120 million passengers per annum within 20 years, the largest capacity in the world, surpassing London's Heathrow's 85 million. Genetic analyses have so far yielded divergent results. A second airport located at Jebel Ali—and a new free trade area within Dubai, marking the centrepiece of the Jebel Ali Airport City—was announced in 2004 and construction began in January 2005. Dog burials at the Mesolithic cemetery of Svaerdborg in Denmark suggest that in ancient Europe dogs were valued companions. When completed this will double the capacity of the airport.

Rock art and skeletal remains indicate that by 14,000 years ago, dogs were present from North Africa across Eurasia to North America. The new terminal will be dedicated to Emirates airlines and will fully support the Airbus A380. Remains of smaller dogs from Mesolithic (Natufian) cave deposits in the Middle East, dated to around 12,000 years ago, have been interpreted as descendants of a lighter Southwest Asian wolf, Canis lupus arabs. A third terminal is currently under construction and due to open in 2006. Their likely ancestor is the large northern Holarctic wolf, Canis lupus lupus. Dubai airport has won many awards for its excellence in design and services. The earliest dog fossils, two crania from Russia and a mandible from Germany, date from 13,000 to 17,000 years ago. Dubai International Airport is a fortress hub for Emirates airlines and has a large Duty Free shopping centre.

Domesticated dogs may have interbred with local populations of wild wolves on several occasions (so-called introgression). Dubai is serviced by several commercial ports and Dubai Creek is still used by local traders in Dhows:. Fossil bone morphologies and genetic analysis of current and ancient dog and wolf populations have not yet been able to conclusively determine whether all dogs descend from a single domestication event, or whether dogs were domesticated independently in more than one location. The emirate discovered that stamp collectors were willing to give it money for colored labels with "Dubai" printed on them, and by the time the postal system was merged with those of other emirates in mid-1972, it had issued over 400 stamps, few of which ever saw usage on mail. Converging archaeological and genetic evidence indicate a time of domestication in the late Upper Paleolithic close to the Pleistocene/Holocene boundary, between 17,000 and 14,000 years ago. This was the opening salvo of a barrage of stamp issues over the next few years. Wolf remains have been found in association with hominid remains dating from 400,000 years ago. The Dubai Post Department took over the postal service on June 14, 1963 and the following day issued a series of stamps depicting sea life, views of Dubai, and Sheikh Maktoum bin Rashid Al Maktoum.

The relationship between man and canine has deep roots. Despite the name, these were only on sale in Dubai's post office. As reflected in the nomenclature, dogs are a subspecies of wolf and are thus still able to interbreed. When Pakistan came into existance, the British government set up a postal administration for Eastern Arabia and used overprinted British stamps until January 7, 1961, when Dubai issued its own stamps inscribed "Trucial States". Molecular systematics indicate that the domestic dog (Canis lupus familiaris) descends from one or more populations of wild wolves (Canis lupus). It used the stamps of India on mail, with postmark "Dubai Persian Gulf", until India's independence in 1947, then stamps of Pakistan until March 31, 1948. In the UK, it is illegal to kill dogs, even if they are on your private land; you are required to contact your local Police Force, DogsTrust, or the local branch of the RSPCA, who will arrange its collection. A post office of British India was opened August 19, 1909.

Feral dogs often form predatory packs that attack livestock and occasionally also prove dangerous to humans. See the Dubai Department of Tourism and Commerce Marketing's list of developments [10] in Dubai for more information. Abandoned domestic dogs who become feral are particularly dangerous; they lack the survival skills of wild canines, as well as the genetic and learned fear of the humans' world. Dubai interests have also purchased large amounts of real estate in foreign countries, in particular snapping up trophy properties in global centers like New York and London; a typical purchase in 2005 was New York's 230 Park Avenue (formerly known as the New York Central Building or the Helmsley Building) and Essex House on Central Park South. Bodies are sometimes tied to fences as warning to other dogs, especially in rural United States and Canada. Iranian expatriates alone are estimated to have invested up to $US 200 Billion in Dubai.[9]. Wild dogs are shot by farmers in an effort to protect livestock. Immigrants have been pouring capital into Dubai in the past several years, greatly contributing to the city's prosperity.

The same creatures that wolves, coyotes, and foxes attack as prey, especially sheep and poultry, are similarly attractive prey to dogs. This project was launched in 2003 and is estimated to be completed by 2006. In most jurisdictions, dogs are destroyed for killing other creatures, so dogs should be prevented from any encounter with livestock or wildlife that might lead to a predatory response. The International Media Production Zone is a project targeted at creating a hub for printers, publishers, media production companies, and related industry segments. With formidable skills and weapons as hunters as well as large and unfussy appetites, dogs often menace livestock and wildlife. The aim of this park is to foster the growth of this sector in Dubai and to utilize the region's talent in addressing this rapidly growing sector. Canine aggression upon humans is ordinarily not tolerated, but any human aggression against an animal having formidable means of self-defense is foolhardy in the extreme. This is a new park to be targeted at Biotech companies working in pharma, medical fields, genetic research and even biodefense.

There are hundreds of shades of provocation that may or may not lead to an attack upon a human. Dubai has also launched Dubiotech. Provocation can range from something as seemingly innocuous as a toddler pulling a dog's tail, in which case the dog might nip to discourage the behavior, to something completely inobvious to humans, such as an odor or a movement that sets a dog off, to blatant human aggression or violence towards a dog, causing it to defend itself. It will also contain Al Burj, another one of the tallest buildings in the world. However, their sharp teeth and claws can inflict injury in an attack; a large dog can knock a human down. Dubai Waterfront will be a mix of canals and islands full of hotels and residential areas that will add 500 miles of man-made waterfront. After thousands of years of domestication and selective breeding for dogs whose aggression towards humans goes no further than a ferocious bark that strongly indicates dislike of a human behavior, most dogs are unlikely to attack people. In February 2005, Dubai Waterfront was announced, it will be 2½ times the size of Washington D.C., the size of the island of Manhattan.

Animals are often given attributes such as "loyal", "cute", and "guardian", but these all have the potential to lure people into a false sense of security. It is expected to be completed in 2008. Humans have a tendency to anthropomorphize animals, particularly pets such as dogs, which are generally portrayed as being "man's best friend". Emaar Properties is currently constructing what will become the world's tallest building, the Burj Dubai. More research is needed to determine the intelligence level of dogs, and the motivations behind their responses to their masters. The city has modern skyscrapers such as Emirates Towers, which are the 12th and 24th tallest buildings in the world[8], and the Burj al-Arab located on the Persian Gulf and is currently the tallest hotel in the world. Despite understandably positive interpretations by dog owners, it is questionable whether these animals are truly capable of feeling emotions on a human level. Somewhere from 2005 to 2006, most of the freehold skyscrapers and other villa projects will be ready for occupancy.

Nevertheless, it is often unwise to anthropomorphize the responses of dogs. The first villa freehold properties that were occupied by non-UAE nationals were The Meadows, The Springs, and The Lakes (upper-class neighborhoods designed by Emaar Properties, collectively called Emirates Hills). Some research demonstrates that dogs are able to convey a depth of emotion not seen to the same extent in any other animal; this is purportedly due to their closely-knit development with modern man, and the survival-benefits of such communication as dogs became more dependent on humans for sustenance. Dubai's land-reclamation projects — the Palm Islands of Jumeira, Jebel Ali, and Deira and The World archipelago — will be the world's largest artificial island complexes, developed with villas, golf courses, and holiday resorts. Many dogs are reported to have separation anxiety if their owner is away for an extended period of time. Corporate office enclaves on Sheikh Zayed road were developed to shift Dubai's traditional business area from the Dubai creek to the western parts of the city. Empirically, dogs are quite dependent on human companionship and may suffer poor health in its absence. The government's decision to diversify from a trade-based but oil-reliant economy to one that is service- and tourism-oriented has made real estate more valuable, and corporations such as Emaar Properties, and Nakheel have benefited.

Many dog owners consider having unconditional acceptance from a friend who is always happy to see them to be quite utilitarian, particularly if the dog also leads them to regular exercise. Despite the relatively early closing time of 3am for these clubs, their trade is brisk. Consequently, dogs are popular as pets and companions, independent of any utilitarian considerations. Besides the obvious presence of prostitutes, however, Dubai also has a lively and well-known nightlife, with many state-of-the-art nightclubs and bars being strewed in all areas of the Emirate, mainly joined to hotels (properties not adjoined to hotels are not allowed to serve alcohol). Relationships between humans and dogs are often characterized by strong emotional bonds. A large population of prostitutes work in Dubai, spurred on by the large amount of tourism [7]. Excitement is evident as they see the hunters load weapons, take to the field, and begin the hunt. [6].

Hunters with dogs report the satisfaction that the dogs seem to exhibit. Through subsequent revisions, the master planned development will span over 3 billion square feet (300,000,000 m²) with the 1st phase to be completed in 2008. Many hound breeds are excellent at treeing raccoons during hunting season. Dubailand, an entertainment city vaguely planned off the concept of Disneyland was launched in October 2003. When trained, beagles are particularly adept at chasing through thick briars and brush after rabbits. Dubai currently has two waterparks in Wonderland and Wild Wadi with more being planned for Dubailand. They typically have large, gentle muzzles to mitigate any potential damage to the game. The World Cup is world's highest stakes horse race, with over US $15 million worth of prize money handed out.

They can follow hand, verbal, and whistle commands at great distance as the hunter directs them to the downed bird. Dubai hosts many world class sporting events, including the Dubai Tennis Open, Dubai Desert Golf Classic, and the Dubai World Cup, an annual horse racing event. At command, they dive into the icy water, swim out and retrieve the birds one by one. Soon to overtake the Mall of Emirates as the world's largest will be the Dubai Mall, part of the Burj Dubai development that will be home to the tallest building in the world when completed. They can spend long hours in a duck blind and, after the hunter has fired at multiple ducks or geese, they can visually spot and remember the location of downed birds. Two more shopping malls have recently opened, the Mall of Emirates, the third largest mall in the world, which also has the world's third largest indoor ski slope, and the Ibn Battuta Mall. As water dogs, the retrievers are unsurpassed. The Oasis Centre caught fire and received major damage on 9 September 2005.

Once the hunter approaches, at his command they will flush the birds to fly and for the hunter to shoot at. The city has many malls such as City Centre, Lamcy Plaza, Al Ghurair City, Mercato Mall, Oasis Centre and Wafi Centre that have international stores, theaters, gaming arcades, and food courts. They have a native ability to discover and "hold" upland game birds; to freeze them momentarily on the ground with their silent, elongated pointing stance. Other, smaller shopping festivals, such as "Dubai Summer Surprises" are held throughout the year. Setters in particular have a long history as upland gun dogs. Attendance at the 2005 Festival topped 3.3 million visitors. This often strengthens the bond between human and dog, since they must trust one another in a variety of environments and must learn how the other works and thinks. The annual month-long Dubai Shopping Festival (DSF) draws shoppers from the Indian subcontinent and around the world.

Many people compete with their dogs in a variety of dog sports, including agility, flyball, and many others. Some of these universities include the American University in Dubai (AUD),The American College of Dubai, Al Ghurair University, Birla Institute of Technology and Science, Middlesex University, Dubai, Dubai Women's College, University of Wollongong in Dubai, and Zayed University. Dogs are also used for searching for or rescuing people and animals, such as in avalanches, at disaster sites, and for missing people or pets. However, a sizable number of foreign accredited universities have been set up in the city over the last ten years. Most modern working dogs are put in positions which capitalize on their sensory or strength and endurance advantages over normal humans. Many expatriates tend to send their children back to their home country for university education. Dogs have served as guides for the blind, as commandos, and have flown into outer space. There are also some primary and high schools that offer Canadian and Japanese syllabuses.

There are service dogs, guard dogs, hunting dogs, and herding dogs. ASD offers an accredited American high school diploma; DAA offers both an American-accredited high school diploma and the International Baccalaureate [IB] diploma. Many breeds of dogs, but not least German Shepherd, Labrador Retriever, and Border Collie are commonly used as working dogs. The American School of Dubai (ASD), which is located in Jumeirah, and Dubai American Academy (DAA) have been around the longest. An assertive dog may consider itself the alpha animal, considering its human master to be subordinate. A growing number of K-12 schools offer the American syllabus. The dog is always aware of its rank relative to other individuals in the group. The International School of Choueifat and Emirates International offer both British and American curricula.

Dogs thrive in human society because their relationships with humans mimic their natural social patterns. The Emirates International School, Al Diyafah High School and Cambridge International High School are also secondary schools that offer a combination of GCSE, IGCSE, and IB courses to the expatriate community. Dog society can be thought of as dog packs characterized by a companionate hierarchy, in which each individual has a rank, and in which there is intense loyalty within the group. Mary's High School, Dubai College, English College, and Jumeirah College are all British style eleven-to-eighteen secondary schools which offer GCSE and A-Levels. Dogs thrive in small social groups or packs which, from their viewpoint, can include humans. St. The relationship between dogs and humans is rooted in history and dogs coexist with humans in a variety of ways. Modern Renaissance School, the Horizon School, Dubai English Speaking School, Jumeirah Primary School, Jumeirah English Speaking School, and Jebel Ali Primary School all offer British style primary education to the age of eleven.

Most dog owners have a large collection of stories about their dogs recognizing individuals by their footsteps outside the door, and so on. Our Own English High School, Modern High School, and Indian High School offer either a CBSE or an ICSE Indian syllabus. This ability to read and deliver nonverbal cues makes dogs expert at reading human beings, as well, often even more so than other humans are, who rely on language. Most schools cater to one or more expatriate communities. Physiologically, this correlates with such features as a large number of nerves innervating the facial muscles of dogs, allowing subtle control of a wide variety of facial expressions; in contrast to cats, for instance, who have many fewer nerves governing their facial muscles, resulting in a smaller repertoire or "vocabulary" of expressions. Some primary schools conduct entrance tests. The requirements of coordinating complex social behavior requires that canines have the ability to sense and deliver a wide variety of cues via body language, more so than for even humans, who can use language for the same purpose. Annual fees for nursery and pre-school vary greatly.

All dogs have a tremendous capacity to learn complex social behavior and to interpret varied body language and sounds, and, like many predators, can react to and learn from novel situations. English is the medium of instruction in most schools in Dubai. Gastric torsion and bloat is a dangerous problem in some large-chested breeds. Christian churches are permitted to openly advertise certain church functions, such as memorial services, in the press. Dogs are also susceptible to the same ailments that humans are, including diabetes, epilepsy, cancer, and arthritis. However, they are permitted to raise money from among their congregants and to receive financial support from abroad. Some breeds of dogs are also prone to certain genetic ailments, such as hip dysplasia, luxating patellas, cleft palate, blindness, or deafness. Apart from donated land for the construction of churches and other religious facilities, including cemeteries, non-Muslim groups are not supported financially or subsidised by the government.

Internal parasites include hookworms, tapeworms, roundworms, and heartworms. Mary's) would begin at the end of 2005, members of the Eastern Orthodox Christian community in the UAE have had to use churches of other denominations for services, until General Sheikh Mohammad Bin Rashid Al Maktoum, Dubai Crown Prince and UAE Defence Minister, donated a plot of land in Jebel Ali. Common external parasites are various species of fleas, ticks, and mites. Construction on the first Greek Orthodox Church in Dubai (to be called St. Diseases commonly associated with dogs include rabies (hydrophobia), canine parvovirus, and canine distemper, and pulmonic stenosis, although there are many others. In early 2001, ground was broken for the construction of several additional churches on a parcel of land in Jebel Ali donated by the government of Dubai for four Protestant congregations and a Catholic congregation. Dogs are susceptible to various diseases, ailments, and poisons, some of which affect humans in the same way, others of which are unique to dogs. The government follows a policy of tolerance towards non-Muslims and Polytheist; in practice, interferes very little in the religious activities of non-Muslims.

It is said that the animals, not just dogs, could sense the tsunami and could therefore flee for life. Non-Muslims in the country are free to practice their religion but may not proselytize publicly or distribute religious literature. For example, during the tsunami in Southern Asia recently, many animals were seen days before fleeing to the hills. There is an electric crematorium run by a group of Indian expatriates. The evolutionary ability of sensing weather can be traced back to when wolves used it to move the pack into proper shelter before a dangerous storm. Both are believed to be sanctioned by the late ruler of Dubai, Sheikh Rashid Bin Saeed Al Maktoum. This is due to their keen ability to detect fluctuations in barometric pressure and can explain a dog's anxiety before and during a storm. The Meena Bazaar area of the city has both a Shiva and Krishna temple.

Dogs also have the ability to sense inclement weather (mainly thunderstorms) many miles away. Dubai is the only emirate that has Hindu temples and a Sikh gurudwara. It has been observed that a lost dog can often find its way home, sometimes traveling over long distances. There are foreign minority Hindus, Sikhs, and Christians as well. An intensive search for a scent, for instance searching a ship for contraband, can actually be very fatiguing for a dog, and the dog must be motivated to continue this hard work for a long period of time. A vast majority of the locals are Sunnis. In any event, it is established by those who train tracking dogs that it is impossible to teach the dog how to track any better than it does naturally; the object instead is to motivate it properly, and teach it to maintain focus on a single track and ignore any others that might otherwise seem of greater interest to an untrained dog. Islam is the official religion of all of the emirates.

The characteristics and behavior of these two types of scent trail would seem, after some thought, to be quite different, the air scent being intermittent but perhaps less obscured by competing scents, whereas the ground scent would be relatively permanent with respect to careful and repetitive search by the dog, but would seem to be much more contaminated with other scents. The official language is Arabic, but English and Urdu are also widely spoken, along with Hindi, Persian, Punjabi, Malayalam, and Tagalog. What information a dog actually detects when he is scenting is not perfectly understood; although once a matter of debate, it now seems to be well established that dogs can distinguish two different types of scents when trailing, an air scent from some person or thing that has recently passed by, as well as a ground scent that remains detectable for a much longer period. The Federal Government is still formulating laws pertaining to ownership of property and considering issuing residency status to those who own such property. Some breeds have been selectively bred for excellence in detecting scents, even compared to their canine brethren. Ownership of lease does not guarantee any form of legal residency status in the UAE. Dogs have nearly 220 million smell-sensitive cells over an area about the size of a pocket handkerchief (compared to 5 million over an area the size of a postage stamp for humans). It is, however, illegal to seek employment on this visa.

They can identify a sound's location much faster than a human can, and they can hear sounds up to four times the distance that humans can. The "lease" on these freehold properties was first offered for 99 years but was later changed to permanent ownership. Dogs detect sounds as low as the 16 to 20 Hz frequency range (compared to 20 to 70 Hz for humans) and as high as 70,000 to 100,000 Hz (compared to 20,000 Hz for humans)2, and in addition have a degree of ear mobility that helps them to rapidly pinpoint the exact location of a sound. There is an increasing number of "freehold" villas and flats on artificial islands such as the Palm Islands. Some breeds, particularly the best sighthounds, have a field of vision up to 270° (compared to 100° to 120° for humans), although broad-headed breeds with their eyes set forward have a much narrower field of vision, as low as 180°.1, 2. The numerous free trade zones allow for full expatriate ownership. Because the lenses of dogs' eyes are flatter than humans', they cannot see as much detail; on the other hand, their eyes are more sensitive to light and motion than humans' eyes. Nearly all of the commercial establishments are run by expatriates with a silent local partner who merely "rents" the business license for a negotiated annual fee without taking part in any capital investment.

It has also been suggested that dogs see in varieties of purple/violet and yellow shades. A quarter of the population reportedly trace their origins to neighboring Iran.[5] The UAE government does not allow any form of naturalization or permanent residence to expatriates. Dogs were thought to be dichromats and thus, by human standards, color blind.1, 2 New research is now being explored that suggests that dogs may actually see some colour, but not to the extent that humans do. The vast majority of these expatriates come from South Asia and the South East Asia. Dogs are predators and scavengers, possessing sharp teeth and strong jaws for attacking, holding, and tearing their food. Dubai is unusual in that its population comprises mainly expatriates, with UAE nationals (Emiratis) constituting the minority. Within the range of extremes, dogs generally share attributes with their wild ancestors, the wolves. Dubai Knowledge Village (KV) is an education and training hub is also set up to complement the Free Zone’s other two clusters, Dubai Internet City and Dubai Media City, by providing the facilities to train the clusters' future knowledge workers.

Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dubai Internet City, now combined with Dubai Media City as part of TECOM (Dubai Technology, Electronic Commerce and Media Free Zone Authority) is one such enclave whose members include IT firms such as EMC Corporation, Oracle, Microsoft, and IBM, and media organisations such as MBC, CNN, Reuters, ARY and AP. Many veterinarians recommend that owners neuter/spay their pets around the age of 5 months. The government has set up industry-specific free zones throughout the city. A female dog can become pregnant on her first heat cycle (which can take place as early as six months), and should be kept away from intact male dogs, including littermates, over the age of 4 months. Dubai is also diversifying as a hub for service-based industries such as IT and finance, with the new Dubai International Financial Centre (DIFC). Contrary to myth, it is not required for a female dog to either experience a heat cycle or have puppies before spaying, and likewise, a male dog does not need the experience of mating before neutering; these myths are responsible for numerous unnecessary health problems and unwanted puppies. Today, Dubai is also an important tourist destination, bolstered by its rapidly-expanding airline Emirates, which is headed by Sheikh Ahmed bin Saeed Al Maktoum, an uncle of the Sheikh.

The hormonal changes involved are sure to change the animal's personality somewhat, and some object to this angle as the sterilization in itself could be carried out without the excision of organs. Oil reserves in Dubai are less than one-twentieth that of the emirate of Abu Dhabi, and hence oil income is a minor contributing factor to the city's prosperity. Spaying and neutering can also help prevent hormone-driven diseases such as breast cancer and prostate cancer, as well as undesired hormone-driven behaviors. The city of Dubai has a free trade in gold and till the 90s was the hub of a "brisk smuggling trade" of gold ingots to India, where gold import was restricted (read the novel Dubai by Robin Moore). It is also common for adult stray dogs who are placed in animal shelters to be euthanized due to lack of space and resources. Most of the new city's banking and financial centers were headquartered in this area. Unwanted puppies are abandoned, eaten, or sometimes disposed of in an inhumane fashion. Dubai and its twin across the Dubai creek, Deira (independent at that time), became important ports of call for Western manufacturers.

Dog experts advise that dogs not intended for further breeding should be spayed or neutered so that they do not have undesired puppies. Dubai maintained its importance as a trade route through the 1970s and 1980s. Spaying or neutering refers to the removal of the male testicles or the female ovaries and uterus, in order to remove the capability to procreate, and to kill the libido. In 1973, Dubai joined the other emirates to adopt a single, uniform currency: the UAE dirham. For example, the Bulldog often requires artificial insemination and almost always requires cesarean section for giving birth. On 2 December 1971 Dubai, together with Abu Dhabi, and five other emirates, formed the United Arab Emirates after Britain left the Persian Gulf in 1971. Some breeds have been developed to emphasize certain physical traits beyond the point at which they can safely bear litters on their own. Oil was discovered 120 kilometres off the coast of Dubai, after which the town granted oil concessions.

Since a mother can only provide nutrients and care to a limited number of offspring, humans must assist in the care and feeding when the litter exceeds approximately eight puppies. After the devaluation of the Gulf Rupee in 1966, Dubai joined the newly independent state of Qatar to set up a new monetary unit, the Qatar/Dubai riyal. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. Until the 1930s, the town was known for its pearl exports. Dogs bear their litters roughly 9 weeks after fertilization. The town of Dubai was an important port of call for foreign tradesmen (chiefly Indians), who settled in the town. This rule is altered in domesticated animals since larger litters are often favoured for economic reasons. The rulers of Dubai fostered trade and commerce, unlike the town's neighbors.

A general rule of thumb is that a mammal will produce half as many offspring as the number of teats on the mother. In March 1892 the Trucial States (or Trucial Oman) were created. The different rates of maturation are responsible for the menarche, not the chronological age. Like four of its neighbours, Abu Dhabi, Ras al-Khaimah, Sharjah and Umm al-Qaiwain, its position on the route to India made it an important location. Like most mammals, the age that a bitch first comes into season is mostly a function of her current body weight as a proportion of her body weight when fully mature. Dubai came under the protection of the United Kingdom (keeping out the Ottoman Turks) by the Exclusive Agreement of 1892. Most bitches come into season for the first time between 6 and 12 months, although some larger breeds delay until as late as 2 years. In 1835, Dubai and the rest of the Trucial States signed a maritime truce with Britain and a "Perpetual Maritime Truce" about two decades later.

Conversely, undomesticated canine species experience estrus once a year, typically in late winter. An attempt by the Qawasim pirates to take over Dubai was thwarted. This is also called in season or in heat. From that point on, Dubai, a newly independent emirate, was constantly at odds with the emirate of Abu Dhabi. The amount of time between cycles varies greatly among different dogs, but a particular dog's cycle tends to be consistent through her life. In 1833, the Al Maktoum dynasty of the Bani Yas tribe left the settlement of Abu Dhabi and took over the town of Dubai, "without resistance". The ability of female domestic dog to come into estrus at any time of the year and usually twice a year is also valued. On 8 Jan 1820 the then sheikh of Dubai was a signatory to the British sponsored "General Treaty of Peace" (the General Maritime Treaty).

In domestic dogs, one of the behaviours that is noted is the abolition of the pair bond seen in wild canines. Earlier in the 18th century the Al Abu Falasa lineage of Bani Yas clan established itself in Dubai which was a dependent of the settlement of Abu Dhabi until 1833. As with most domesticated species, one of the first and strongest effects seen from selective breeding is selection for cooperation with the breeding process as directed by humans. There are records of the town of Dubai from 1799. Dog owners may accidentally allow their pets to breed without regard to bloodlines. . Dog breeders also have accurate information on the complexities of the reproductive process for the breed of dog that they are accustomed to handling. A majority of the emirate's revenues are from the Jebel Ali Free Zone (JAFZ) [4] and now, increasingly, from tourism.

Dog breeders have access to records which allow them to accurately guess which characteristics will "breed true" in a particular dog. Dubai is distinct from other members of the UAE in that revenues from oil account for only 6% of its gross domestic product. Breeders who do this are usually experienced in this process. The town of Hatta is an exclave of the emirate of Dubai and borders Al Wajajah, Oman. Sometimes dogs are bred to create puppies to sell, or sometimes to carry on an award-winning purebred line. The emirate is located on the Persian Gulf, southwest of Sharjah and northeast of Abu Dhabi, and reaches into the interior. Among professional breeders, dogs are only allowed to mate for a specific purpose. Dubai is the second largest emirate in the federation after Abu Dhabi.

Dogs also may find some poisons attractive, including antifreeze and snail bait. Sheikh Mohammed bin Rashid Al Maktoum, who was earlier the crown prince of Dubai is one of the Sheikh's younger brothers. Alcoholic beverages pose much the same temptation and hazard to dogs as to humans. The new Ruler who is also the Vice-President and the Prime Minister of the UAE is H.H. Some human medications, such as acetaminophen/paracetamol (Tylenol), are highly toxic to dogs. Sheikh Maktoum bin Rashid Al Maktoum, who was also the Vice-President of the federation of the United Arab Emirates. Some foods commonly enjoyed by humans are dangerous to dogs, including chocolate (Theobromine poisoning), onions, grapes and raisins, Macadamia nuts, and hops. The ruler of Dubai was the late H.H.

For a discussion on one use of treats in training, see clicker training. Dubai or Dubayy (in Arabic: دبيّ, IPA /ðʊ'bɪ/, generally /dʊ'baɪ/ in English) refers to either. Such dogs might consider anything dropped by humans, including small but indigestible objects (such as marbles, coins, rings, etc.), to be treats as well, which could be dangerous to the dogs when ingested. Published: December 4, 2005. Many dogs consider anything given to them directly by hand to be a treat, even the food they are accustomed to at meal time. FATTAH. Eating grass might make the dog vomit, so one explanation is that dogs eat grass to remove unwanted content from their stomachs. ^  "Young Iranians Follow Dreams to Dubai." The New York Times, by HASSAN M.

Explanations abound, but rationales such as that it neutralizes acid are just guesses. Jebel Ali. Dogs sometimes eat grass, a harmless activity. Mina' Rashid. This research is also true of other mammals. 1949). It has also been noted that extremely stressful conditions, such as the Iditarod race and scientific studies of similar conditions, suggest that high-protein diets including meat help prevent damage to muscle tissue. 4 Jan 2006 - Present Sheikh Mohammed bin Rashid Al Maktoum (b.

In the wild these diets are typically pursued in the absence of available meat. 2006). Some sources suggest that a dog fed on a stict vegetarian diet may develop dilated cardiomyopathy since it lacks L-carnitine.[3]. 1943 - d. Domestic dogs can survive healthily on a reasonable and carefully designed vegetarian diet, particularly if eggs and milk products are included. 7 Oct 1990 - 4 Jan 2006 Sheikh Maktoum III ibn Rashid Al Maktoum (b. Wild canines not only eat available plants to obtain key amino acids, but may also obtain nutrients from vegetable matter from the stomach contents of their herbivorous prey. 1990).

Dogs are able to healthily digest a variety of foods including vegetables and grains, and in fact can consume a large proportion of these in their diet. 1912 - d. Unlike an obligate carnivore, such as a cat, a dog is not dependent on meat protein in order to fulfill its dietary requirements. Sep 1958 - 7 Oct 1990 Sheikh Rashid II ibn Said Al Maktoum (b. The classification in the Order Carnivora does not necessarily mean that a dog's diet must be restricted to meat. 18 April 1929 - Sep 1958 Sheikh Said II ibn Maktoum (2nd time) (s.a.). Presently, there is academic discussion as to whether domestic dogs are omnivores or carnivores. 15 April 1929 - 18 April 1929 Sheikh Mani ibn Rashid.

For a detailed discussion on what dog intelligence is, see dog intelligence. 1958). Anecdotal evidence suggests that dogs have a reasonably high intelligence. 1878 - d. Among dog lovers, dogs are generally valued for their intelligence. Nov 1912 - 15 April 1929 Sheikh Said II ibn Maktoum (1st time) (b. They have small, tight feet, and walk on their toes. 1912).

Its skeleton provides the ability to run and leap. 1851 - d. Like most other predatory mammals, the dog has powerful muscles, a cardiovascular system that supports both sprinting and endurance, and teeth for catching, holding, and tearing. 16 Feb 1906 - Nov 1912 Sheikh Bati ibn Suhayl (b. Although selective breeding has changed the appearance of many breeds, all dogs retain the basic ingredients from their distant ancestors. 1906). Many additional terms are used for dogs that are not purebred; see Terms for mixed-breed dogs. - d.

The word is sometimes used to refer collectively to any mammal belonging to the family Canidae (as in "the dog family"), such as wolves, foxes and coyotes. 18. Dog, in common usage, refers to the domestic pet dog, Canis lupus familiaris (originally classified as Canis familiaris by Linnaeus in 1758, but reclassified as a subspecies of the wolf, Canis lupus, by the Smithsonian Institution and the American Society of Mammalogists in 1993). 7 April 1894 - 16 Feb 1906 Sheikh Maktoum II ibn Hushur (b. . 1894). In other cultures, some dogs are used as food. 22 Nov 1886 - 7 April 1894 Sheikh Rashid I ibn Maktoum (d.

Dogs have lived with and worked with humans in so many roles that their loyalty has earned them the sobriquet "man's best friend." Conversely, some cultures consider dogs to be unclean. 1886). In many countries, the most common and perhaps most important role of dogs is as companions. 1859 - 22 Nov 1886 Sheikh Hushur ibn Maktoum (d. For dogs that do not have traditional jobs, a wide range of dog sports provide the opportunity to exhibit their natural skills. 1859). Dogs fill a variety of roles in human society and are often trained as working dogs. 1852 - 1859 Sheikh Said I ibn Bati (d.

Dogs, like humans, are highly social animals and pack hunters; this similarity in their overall behavioral pattern accounts for their trainability, playfulness, and ability to fit into human households and social situations. 1852). For example, heights at the withers range from just a few inches (such as the Chihuahua) to roughly three feet (such as the Irish Wolfhound), and colors range from white to black, with reds, grays (usually called blue), and browns occurring in a tremendous variation of patterns. 9 June 1833 - 1852 Sheikh Maktoum I ibn Bati ibn Suhayl (d. In this time, the dog has developed into hundreds of breeds with a great degree of variation. - 9 June 1833 Sheikh `Ubayd ibn Said. Dogs were first domesticated from wolves at least 15000 years ago[1] but perhaps as long as 150,000 years ago based on recent genetic fossil evidence and DNA evidence[2]. ...

The dog is a canine mammal of the Order Carnivora. that emirate's main city, sometimes called "Dubai City" to distinguish it from the emirate. It too has the body plan of an adult canine predator. one of the seven emirates that make up the United Arab Emirates on the Arabian Peninsula, or. The least paedomorphic behavior pattern may be that of the basenji, bred in Africa to hunt alongside humans almost on a peer basis; this breed is often described as highly independent, neither needing nor appreciating a great deal of human attention or nurturing, often described as "catlike" in its behavior. Terriers similarly have adult aggressive behavior, famously coupled with a lack of juvenile submission, and display correspondingly adult physical features such as erect ears, although many breeds have also been selected for size and sometimes dwarfed legs to enable them to pursue prey in their burrows.

This contrasts with sighthounds, who pursue and attack perceived prey on sight, and who maintain the mature canine body type with erect ears, lean bodies, and adult coats. Scenthounds maintain an intermediate body type and behavior pattern that causes them to actually pursue prey by tracking their scent, but tend to refrain from actual individual attacks in favor of vocally summoning the pack leaders (in this case, humans) to do the job. Their physical characteristics are closer to that of the mature wild canine than the sheepdog breeds, but they typically do not have erect ears, etc. Similarly, they seize dead or wounded prey and bring it back to the "pack", even though they did not attack it themselves, that is, "retrieving" behavior.

They identify potential prey and freeze into immobility, for instance, but refrain from then stalking the prey as an adult predator would do next; this results in the "pointing" behavior for which such dogs are bred. Gun dog breeds used in hunting—that is, pointers, setters, spaniels, and retrievers—have an intermediate degree of paedomorphism; they are at the point where they share in the pack's hunting behavior, but are still in a junior role, not participating in the actual attack. (Compare to the physical appearance of the border collie, a sheep herding dog, whose physical configuration is closer to that of an adult wild canine and who therefore has a greater capacity to frighten sheep into a desired pattern of movement, along with the more adult aggressive temperament to do so). In addition, they retain very juvenile physical characteristics such as round bodies and heads, soft coats, ears that hang down, and so on, which do not elicit fear responses from the sheep in the way that an appearance similar to that of an adult wolf would.

Livestock guardian dogs retain the most juvenile characteristics: they stay close to home with their foster "litter" (which might include a flock of sheep), rather than going out hunting, they have almost no predatory behavior (which would be disastrous in the vicinity of such a natural prey stimulus as sheep), they respond to perceived threats with a lot of vocalization and attempts to alert and engage the dominant individuals in their "pack" (i.e. humans) whenever possible, engaging in actual combat only as a last resort. Canine in common usage is a synonym for dog or an adjective meaning dog; for example, in the common expression "canine companion". Pooch, Poochie, Pup, Puppy, Doggy, Doggie are all informal and affectionate terms for a dog often used by children. Puppy is a juvenile dog.

Pack is used to denote a group of dogs. Bitch is a female dog. Dog is also a term used by breeders to specifically denote a male domestic dog.
