(September 2007) () Purebreds, also called purebreeds, are cultivated varieties or cultivars of an animal, achieved through the process of. When the of a purebred animal is recorded, that animal is said to be pedigreed. The term purebred is occasionally confused with the proper noun, which refers exclusively to a specific of, one of the first breeds for which a written national was created since the 18th century. Thus a purebred animal should never be called a 'thoroughbred' unless the animal actually is a registered Thoroughbred horse.
Contents • • • • • • • • • • True breeding [ ] In the world of, to 'breed true' means that specimens of an animal will breed true-to-type when mated like-to-like; that is, that the progeny of any two individuals in the same breed will show consistent, replicable and predictable characteristics. A puppy from two purebred dogs of the same breed, for example, will exhibit the traits of its parents, and not the traits of all breeds in the subject breed's ancestry. However, breeding from too small a gene pool, especially direct, can lead to the passing on of undesirable characteristics or even a collapse of a breed population due to. Therefore, there is a question, and often heated controversy, as to when or if a breed may need to allow 'outside' stock in for the purpose of improving the overall health and vigor of the breed.
Because pure-breeding creates a limited, purebred animal breeds are also susceptible to a wide range of congenital health problems. This problem is especially prevalent in competitive dog breeding and dog show circles due to the singular emphasis on aesthetics rather than health or function. Such problems also occur within certain segments of the horse industry for similar reasons.
The problem is further compounded when breeders practice. The opposite effect to that of the restricted gene pool caused by pure-breeding is known as, which generally results in healthier animals. Pedigrees [ ]. Pure-breed Zwergschnauzer A purebred dog is a dog of a, with written documentation showing the individual purebred dog's descent from its breeds' [ – ]. In dogs, the term breed is used two ways: loosely, to refer to or of dog (also called natural breeds or ancient breeds); or more precisely, to refer to modern breeds of dog, which are documented so as to be known to be descended from specific ancestors, that closely resemble others of their breed in appearance, movement, way of working and other characters; and that reproduce with offspring closely resembling each other and their parents.
Purebred dogs are breeds in the second sense. New breeds of dog are constantly being created, and there are many websites for new breed associations and breed clubs offering legitimate registrations for new or rare breeds. When dogs of a new breed are 'visibly similar in most characteristics' and have reliable documented descent from a 'known and designated foundation stock', then they can then be considered members of a breed, and, if an individual dog is documented and registered, it can be called purebred. Ava Uav Hack Download. Purebred horses [ ] The resulted in a small number of domesticated stallions (possibly a single male ancestor) being crossed on wild mares that had adapted to local conditions. This ultimately produced of four basic body types, once thought to be wild prototypes, but now considered to be. Many of these animals were then bred true to original type by selected breeding, though emphasizing certain inherent traits (such as a good temperament, suitable to training by humans) to a greater degree than others.
In other cases, horses of different body types were until a desired characteristic was achieved and bred true. Written and oral histories of various animals or pedigrees of certain types of horse have been kept throughout history, though stud books trace only to about the 13th century, at least in, when pedigrees were tracked in writing, and the practice of declaring a type of horse to be a breed or a purebred became more widespread. Certain, such as the and the, are claimed by aficionados of the respective breeds to be ancient, near-pure descendants from an ancient wild prototype, though mapping of the horse genome as well as the and of various breeds has largely disproved such claims.
Purebred cats [ ]. Purebred Himalayan A cat whose is formally registered is called a. Technically, a purebred cat is one whose ancestry contains only individuals of the same breed.
A pedigreed cat is one whose ancestry is recorded, but may have ancestors of different breeds. The is quite large: most cat registries actually recognize between 30 and 40 breeds of cats, and several more are in development, with one or more new breeds being recognized each year on average, having distinct features and heritage. Owners and breeders compete in cat shows to see whose animal bears the closest resemblance (best conformance) to an idealized definition, based on and the for each breed.
Because of common crossbreeding in populated areas, many cats are simply identified as belonging to the mixed types of and, depending on their type of fur. Some original cat breeds that have a distinct phenotype that is the main type occurring naturally as the dominant domesticated cat type in their region of origin are sometimes considered subspecies and in the past received names as such, although this is no longer supported by feline biologists. Silvestris the wild cat and F. Catus the domestic. Some of these cat breeds (with their invalid scientific names for historical interest) are: [ – ] • F.

Calves that were transferred as embryos, with their and Hereford recipient mothers. Most domesticated animals also have true-breeding breeds and, particularly,,,, and. While animals bred strictly for market sale are not always purebreds, or if purebred may not be registered, most livestock producers value the presence of purebred genetic stock for the consistency of traits such animals provide. It is common for a farm's male breeding stock in particular to be of purebred, pedigreed lines. In cattle, some breeders associations make a difference between 'purebred' and 'full blood'. Full blood cattle are fully pedigreed animals, where every ancestor is registered in the herdbook and shows the typical characteristics of the breed.
Purebred are those animals that have been bred-up to purebred status as a result of using full blood animals to cross with an animal of another breed. The breeders association rules the percentage of fullblood genetics required for an animal to be considered purebred, usually above 87.5%. Artificial breeding via or is often used in sheep and cattle breeding to quickly expand, or improve purebred herds. Embryo transfer techniques allow top quality female to have a greater influence on the genetic advancement of a herd or flock in much the same way that artificial insemination has allowed greater use of superior sires. Wild species, landraces, and purebred species [ ].
See also: and Breeders of purebred species discourage with wild species, unless a deliberate decision is made to incorporate a trait of a wild ancestor back into a given breed or strain. Wild populations of animals and plants have evolved naturally over millions of years through a process of in contrast to human controlled or for desirable traits from the human point of view.
Normally, these two methods of reproduction operate independently of one another. However, an intermediate form of selective breeding, wherein animals or plants are bred by humans, but with an eye to adaptation to natural region-specific conditions and an acceptance of natural selection to weed out undesirable traits, created many ancient domesticated breeds or types now known as. Many times, species live in or near areas which also still hold naturally evolved, region-specific ancestor species and subspecies. In some cases, a domesticated species of plant or animal may become, living wild.
Other times, a wild species will come into an area inhabited by a domesticated species. Some of these situations lead to the creation of plants or animals, a cross between the native species and a domesticated one. This type of crossbreeding, termed by those who are concerned about preserving the genetic base of the wild species, has become a major concern. Hybridization is also a concern to the breeders of purebred species as well, particularly if the gene pool is small and if such crossbreeding or hybridization threatens the genetic base of the domesticated purebred population.
The concern with genetic pollution of a wild population is that hybridized animals and plants may not be as genetically strong as naturally evolved region specific wild ancestors which can survive without human and have high immunity to natural diseases. The concern of purebred breeders with wildlife hybridizing a domesticated species is that it can coarsen or degrade the specific qualities of a breed developed for a specific purpose, sometimes over many generations. Thus, both purebred breeders and wildlife biologists share a common interest in preventing accidental hybridization.

Montage showing the morphological variation of the dog. The domestic dog ( Canis lupus familiaris or Canis familiaris) is a in the, and is the most widely abundant terrestrial. The dog and the are as modern wolves are not closely related to the wolves that were first, which implies that the direct ancestor of the dog is. The dog is the first to be domesticated and has been over millennia for various behaviors, sensory capabilities, and physical attributes. New research seems to show that the dog's high sociability may be affected by 'the same genes as in humans.' Their has led dogs to be uniquely attuned to human behavior and they are able to thrive on a starch-rich diet that would be inadequate for other canid species. Dogs vary widely in shape, size and colors.
Dogs perform many roles for people, such as,,,, and, and, more recently, and roles. This influence on human society has given them the '. Main article: The origin of the domestic dog is not clear.
It is known that the dog was the first domesticated species. The domestic dog is a member of the genus (canines), which forms part of the, and is the most widely abundant terrestrial carnivore. The closest living relative of the dog is the and there is no evidence of any other canine contributing to its genetic lineage.
The dog and the gray wolf form two sister, with modern wolves not closely related to the wolves that were first domesticated. The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago.
These dates imply that the earliest dogs arose in the time of human and not. Where the of dog and wolf took place remains controversial, with the most plausible proposals spanning Western Europe, Central Asia, and East Asia. This has been made more complicated by the most recent proposal that fits the available evidence, which is that an initial wolf population split into East and West Eurasian wolves, these were then domesticated independently before going extinct into two distinct dog populations between 14,000-6,400 years ago, and then the Western Eurasian dog population was partially and gradually replaced by East Asian dogs that were brought by humans at least 6,400 years ago. Main article: Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern show more variation in size, appearance, and behavior than any other domestic animal. Dogs are and, and like many other predatory mammals, the dog has powerful muscles, fused wrist bones, a cardiovascular system that supports both sprinting and endurance, and teeth for catching and tearing. Size and weight Dogs are highly variable in height and weight.
The smallest known adult dog was a, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body, and weighed only 113 grams (4.0 oz). The largest known dog was an which weighed 155.6 kg (343 lb) and was 250 cm (98 in) from the snout to the tail.
The tallest dog is a that stands 106.7 cm (42.0 in) at the shoulder. Senses The dog's senses include vision, hearing, sense of smell, sense of taste, touch and sensitivity to the earth's magnetic field. Another study suggested that dogs can see the earth's magnetic field.
See further: Coat. A with a golden shade of coat. Shades of coat colors can vary within breeds of dogs. For example, some Golden Retrievers have light, almost cream colored coats, and others may have dark, brownish shades of coat.
The of domestic dogs are of two varieties: 'double' being common with dogs (as well as wolves) originating from colder climates, made up of a coarse and a soft, or 'single', with the topcoat only. Domestic dogs often display the remnants of, a common natural camouflage pattern.
A countershaded animal will have dark coloring on its upper surfaces and light coloring below, which reduces its general visibility. Thus, many breeds will have an occasional 'blaze', stripe, or 'star' of white fur on their chest or underside. Regarding coat appearance or health, the coat can be maintained or affected by multiple nutrients present in the diet, see for more information. Main article: There are many household plants that are poisonous to dogs including, and. Some breeds of dogs are prone to certain genetic ailments such as and,,,,, and.
Two serious medical conditions particularly affecting dogs are, affecting females of all types and ages, and (bloat), which affects the larger breeds or deep-chested dogs. Both of these are acute conditions, and can kill rapidly. Dogs are also susceptible to parasites such as,, and, as well as,,, and. A number of common human foods and household ingestibles are toxic to dogs, including (), onion and (, or poisoning), and,,, as well as various plants and other potentially ingested materials. The nicotine in tobacco can also be dangerous.
Dogs can be exposed to the substance by scavenging garbage or ashtrays; eating cigars and cigarettes. Signs can be vomiting of large amounts (e.g., from eating cigar butts) or diarrhea. Some other signs are abdominal pain, loss of coordination, collapse, or death. Dogs are highly susceptible to, typically from ingestion of. Theobromine is toxic to dogs because, although the dog's metabolism is capable of breaking down the chemical, the process is so slow that even small amounts of chocolate can be fatal, especially dark chocolate.
Dogs are also vulnerable to some of the same health conditions as humans, including, dental and heart disease, epilepsy, cancer, hypothyroidism, and arthritis. A mixed-breed terrier. Mixed-breed dogs have been found to run faster and live longer than their pure-bred parents (See ) In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds, and that increasing body-weight was negatively correlated with longevity (i.e. The heavier the dog the shorter its lifespan). The typical lifespan of dogs varies widely among breeds, but for most the median longevity, the age at which half the dogs in a population have died and half are still alive, ranges from 10 to 13 years.
Individual dogs may live well beyond the median of their breed. The breed with the shortest lifespan (among breeds for which there is a questionnaire survey with a reasonable sample size) is the, with a median longevity of about 5.2 years, but several breeds, including,, and are nearly as short-lived, with median longevities of 6 to 7 years. The longest-lived breeds, including,,, and, have median longevities of 14 to 15 years.
The median longevity of, taken as an average of all sizes, is one or more years longer than that of purebred dogs when all breeds are averaged. The dog widely reported to be the longest-lived is ', who died in 1939 and was claimed to be 29.5 years old at the time of his death. On 5 December 2011,, the world's oldest living dog recognized by, died aged 26 years and 9 months. Dog nursing newborn puppies In domestic dogs, begins to happen around age six to twelve months for both males and females, although this can be delayed until up to two years old for some large breeds. This is the time at which female dogs will have their first.
They will experience subsequent estrous cycles semiannually, during which the body prepares for. At the peak of the cycle, females will come into estrus, being mentally and physically receptive to. Because the survive and are capable of being fertilized for a week after ovulation, it is possible for a female to mate with more than one male. Fertilization typically occurs 2–5 days after ovulation; 14–16 days after ovulation, the embryo attaches to the uterus, and after 7-8 more days the heart beat is detectable. Dogs bear their litters roughly 58 to 68 days after, with an average of 63 days, although the length of gestation can vary. An average litter consists of about six, though this number may vary widely based on the breed of dog. In general, produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.
Some dog breeds have acquired traits through selective breeding that interfere with reproduction. Male, for instance, are incapable of mounting the female. For many dogs of this breed, the female must be in order to reproduce.
A feral dog from nursing her four puppies refers to the of animals, usually by or the female's and, in order to eliminate the ability to procreate and reduce. Because of the in some countries, many animal control agencies, such as the (ASPCA), advise that dogs not intended for further breeding should be neutered, so that they do not have undesired puppies that may have to later be euthanized. According to the, 3–4 million dogs and cats are each year in the United States and many more are confined to cages in shelters because there are many more animals than there are homes. Spaying or castrating dogs helps keep overpopulation down.
Local humane societies, SPCAs, and other urge people to neuter their pets and to adopt animals from shelters instead of purchasing them. Neutering reduces problems caused by, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs.
However, neutering increases the risk of in female dogs, and in males, as well as,, rupture, obesity, and in either sex. Inbreeding depression A common breeding practice for pet dogs is mating between close relatives (e.g. Between half- and full siblings). In a study of seven different French breeds of dogs (,,,, dog,, and ) it was found that inbreeding decreases litter size and survival. Another analysis of data on 42,855 litters, found that as the increased, litter size decreased and the percentage of stillborn puppies increased, thus indicating inbreeding depression. About 22% of boxer puppies die before reaching 7 weeks of age. Stillbirth is the most frequent cause of death, followed by infection.
Mortality due to infection was found to increase significantly with increases in inbreeding. Is considered to be due largely to the expression of homozygous deleterious recessive mutations. Outcrossing between unrelated individuals, including dogs of different breeds, results in the beneficial masking of deleterious recessive mutations in progeny. Intelligence, behavior and communication Intelligence. Main article: Dog intelligence is the ability of the dog to perceive information and retain it as knowledge for applying to solve problems.
Dogs have been shown to learn by inference. A study with showed that he knew the labels of over 200 different items.
He inferred the names of novel items by exclusion learning and correctly retrieved those novel items immediately and also 4 weeks after the initial exposure. Dogs have advanced memory skills. A study documented the learning and memory capabilities of a border collie, 'Chaser', who had learned the names and could associate by verbal command over 1,000 words.
Dogs are able to read and react appropriately to human body language such as gesturing and pointing, and to understand human voice commands. Dogs demonstrate a by engaging in deception. An experimental study showed compelling evidence that Australian can outperform domestic dogs in non-social problem-solving, indicating that domestic dogs may have lost much of their original problem-solving abilities once they joined humans. Another study indicated that after undergoing training to solve a simple manipulation task, dogs that are faced with an insoluble version of the same problem look at the human, while socialized wolves do not. Modern domestic dogs use humans to solve their problems for them. Main article: Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli.
As the oldest domesticated species, with estimates ranging from 9,000–30,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes but rather parallel some of the social-cognitive skills of human children. Traits of high sociability and lack of fear in dogs may include genetic modifications related to in humans, which cause at the expense of problem solving ability. Main article: Dog communication is about how dogs 'speak' to each other, how they understand messages that humans send to them, and how humans can translate the ideas that dogs are trying to transmit.: xii These communication behaviors include eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs) and gustatory communication (scents, pheromones and taste).
Humans communicate with dogs by using vocalization, hand signals and body posture. Comparison with wolves. The carries more DNA than any other dog breed Physical characteristics Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel of red blood cell acid. The are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled.
Compared with equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.: 35 The teeth of gray wolves are also proportionately larger than those of dogs. Dogs have a more domed forehead and a distinctive 'stop' between forehead and nose. The that closes the jaws is more robust in wolves.: p158 Wolves do not have on their back legs, unless there has been admixture with dogs that had them. Most dogs lack a functioning and enter twice yearly, unlike gray wolves which only do so once a year. So-called primitive dogs such as Dingoes and Basenjis retain the yearly estrus cycle. Dogs generally have brown eyes and wolves almost always have amber or light colored eyes. The skin of domestic dogs tends to be thicker than that of wolves, with some tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather.
The paws of a dog are half the size of those of a wolf, and their tails tend to curl upwards, another trait not found in wolves The dog has developed into hundreds of varied, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the ranges from a 6 inches (150 mm) in the to 3.3 feet (1.0 m) in the; color varies from white through grays (usually called 'blue') to black, and browns from light (tan) to dark ('red' or 'chocolate') in a wide variation of patterns; can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to their coat. Behavioral differences. See also: Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors. In 2016, a study found that there were only 11 fixed genes that showed variation between wolves and dogs.
These gene variations were unlikely to have been the result of natural evolution, and indicate selection on both morphology and behavior during dog domestication. These genes have been shown to affect the pathway, with the majority of the genes affecting the fight-or-flight response (i.e. Selection for tameness), and emotional processing.
Dogs generally show reduced fear and aggression compared with wolves. Some of these genes have been associated with aggression in some dog breeds, indicating their importance in both the initial domestication and then later in breed formation. Ecology Population and habitat The global dog population is estimated at 900 million and rising. Although it is said that the regarding 17–24% of dogs in developed countries, in the developing world they are feral, village or community dogs, with pet dogs uncommon.
Most of these dogs live their lives as scavengers and have never been owned by humans, with one study showing their most common response when approached by strangers is to run away (52%) or respond aggressively. Little is known about these dogs, or the dogs in developed countries that are feral, stray or are in shelters, as the majority of modern research on dog cognition has focused on pet dogs living in human homes.
Competitors Being the most abundant and widely distributed terrestrial carnivores, feral and have the greatest potential to compete with other carnivores. A review of the studies in the competitive effects of dogs on carnivores did not mention any research on competition between dogs and wolves. Competition would favor the wolf as it is known to kill dogs, however wolves tend to live in pairs or in small packs in areas where they are highly persecuted, giving them a disadvantage facing large dog groups.
Wolves kill dogs wherever they are found together. One survey claims that in Wisconsin in 1999 more compensation had been paid for dog losses than livestock, however in Wisconsin wolves will often kill hunting dogs, perhaps because they are in the wolf's territory.
Some wolf pairs have been reported to prey on dogs by having one wolf lure the dog out into heavy brush where the second animal waits in ambush. In some instances, wolves have displayed an uncharacteristic fearlessness of humans and buildings when attacking dogs, to the extent that they have to be beaten off or killed. Although the numbers of dogs killed each year are relatively low, it induces a fear of wolves entering villages and farmyards to take dogs.
In many cultures, there are strong social and emotional bonds between humans and their dogs that can be seen as family members or working team members. The loss of a dog can lead to strong emotional responses with demands for more liberal wolf hunting regulations. And big cats have also been known to attack dogs. In particular are known to have a predilection for dogs, and have been recorded to kill and consume them regardless of their size or ferocity. In,,, and are reputed to kill dogs with the same vigor as leopards. Are major predators of stray dogs in,, and the.
The spiked collar common on working and pet dogs is no mere ornament: it originated as a protection of the vulnerable neck of a dog from wolves, but also protects dogs from attacks by other dogs. Gnawing a pig's foot Despite their descent from wolves and classification as, dogs are variously described in scholarly and other writings as.
Unlike, dogs can adapt to a wide-ranging diet, and are not dependent on meat-specific protein nor a very high level of protein in order to fulfill their basic dietary requirements. Dogs will healthily digest a variety of foods, including vegetables and grains, and can consume a large proportion of these in their diet, however all-meat diets are not recommended for dogs due to their lack of calcium and iron. Comparing dogs and wolves, dogs have adaptations in genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet. Demonstrate different colored coats within the one breed Most of dog are at most a few hundred years old, having been artificially selected for particular and by people for specific functional roles. Through this, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the ranges from 15.2 centimetres (6.0 in) in the to about 76 cm (30 in) in the; color varies from white through grays (usually called 'blue') to black, and browns from light (tan) to dark ('red' or 'chocolate') in a wide variation of patterns; can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to this coat.
While all dogs are genetically very similar, and selective breeding have reinforced certain characteristics in certain populations of dogs, giving rise to dog types and dog breeds. Dog types are broad categories based on function, genetics, or characteristics. Dog breeds are groups of animals that possess a set of inherited characteristics that distinguishes them from other animals within the same species. [ ] [ ] Modern dog breeds are non-scientific classifications of dogs kept by modern.
Purebred dogs of one breed are genetically distinguishable from dogs of other breeds, but the means by which kennel clubs classify dogs is unsystematic. DNA analyses of 85 dog breeds showed they fell into four major types of dogs that were statistically distinct. These include the 'old world dogs' (e.g., and ), 'Mastiff'-type (e.g., ), 'herding'-type (e.g., ), and 'all others' (also called 'modern'- or 'hunting'-type). Roles with humans. And, the lead dog on the last relay team of the. Domestic dogs inherited complex behaviors, such as, from their wolf ancestors, which would have been with complex body language.
These sophisticated forms of social cognition and communication may account for their trainability, playfulness, and ability to fit into human households and social situations, and these attributes have given dogs a relationship with humans that has enabled them to become one of the most successful species on the planet today.: pages95-136 The dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as,,,, and,, and, more recently,.
This influence on human society has given them the nickname ' in the Western world. Mydefrag Scripts Download Free. In some cultures, however, dogs.
Early roles Wolves, and their dog descendants, would have derived significant benefits from living in human camps—more safety, more reliable food, lesser caloric needs, and more chance to breed. They would have benefited from humans' upright gait that gives them larger range over which to see potential predators and prey, as well as better color vision that, at least by day, gives humans better visual discrimination. Camp dogs would also have benefited from human tool use, as in bringing down larger prey and for a range of purposes. The dogs of are twice the size of those seen in India, with large heads and hairy bodies. They are powerful animals, and are said to be able to kill a tiger. During the day they are kept chained up, and are let loose at night to guard their masters' house. Humans would also have derived enormous benefit from the dogs associated with their camps.
For instance, dogs would have improved sanitation by cleaning up food scraps. Dogs may have provided warmth, as referred to in the Australian Aboriginal expression 'three dog night' (an exceptionally cold night), and they would have alerted the camp to the presence of predators or strangers, using their acute hearing to provide an early warning. Anthropologists believe the most significant benefit would have been the use of dogs' robust sense of smell to assist with the hunt. The relationship between the presence of a dog and success in the hunt is often mentioned as a primary reason for the domestication of the wolf, and a 2004 study of hunter groups with and without a dog gives quantitative support to the hypothesis that the benefits of cooperative hunting was an important factor in wolf domestication. The cohabitation of dogs and humans would have greatly improved the chances of survival for early human groups, and the domestication of dogs may have been one of the key forces that led to human success.
Emigrants from that walked across the into North America may have had dogs in their company, and one writer suggests that the use of may have been critical to the success of the waves that entered North America roughly 12,000 years ago, although the earliest archaeological evidence of dog-like canids in North America dates from about 9,400 years ago.: 104 Dogs were an important part of life for the population in North America, and were their only domesticated animal. Dogs also carried much of the load in the migration of the and tribes 1,400 years ago. Use of dogs as in these cultures often persisted after the introduction of the to North America. Green velvet dog collar, dates from 1670 to 1690. It is estimated that three-quarters of the world's dog population lives in the developing world as feral, village, or community dogs, with pet dogs uncommon. 'The most widespread form of interspecies bonding occurs between humans and dogs' and the keeping of dogs as companions, particularly by elites, has a long history.
(As a possible example, at the site of in, dated to 12,000 BC, the remains of an elderly human and a four-to-five-month-old puppy were found buried together). However, pet dog populations grew significantly after World War II as suburbanization increased. In the 1950s and 1960s, dogs were kept outside more often than they tend to be today (using the expression 'in the doghouse' to describe exclusion from the group signifies the distance between the doghouse and the home) and were still primarily functional, acting as a guard, children's playmate, or walking companion.
From the 1980s, there have been changes in the role of the pet dog, such as the increased role of dogs in the emotional support of their human guardians. People and dogs have become increasingly integrated and implicated in each other's lives, to the point where pet dogs actively shape the way a family and home are experienced.
There have been two major trends in the changing status of pet dogs. The first has been the 'commodification' of the dog, shaping it to conform to human expectations of personality and behaviour. The second has been the broadening of the concept of the family and the home to include dogs-as-dogs within everyday routines and practices. There are a vast range of commodity forms available to transform a pet dog into an ideal companion.
The list of goods, services and places available is enormous: from dog perfumes, couture, furniture and housing, to dog groomers, therapists, trainers and caretakers, dog cafes, spas, parks and beaches, and dog hotels, airlines and cemeteries. While as an organized activity can be traced back to the 18th century, in the last decades of the 20th century it became a high-profile issue as many normal such as barking, jumping up, digging, rolling in dung, fighting, and (which dogs do to establish territory through scent), became increasingly incompatible with the new role of a pet dog.
Dog training books, classes and television programs proliferated as the process of commodifying the pet dog continued. The majority of contemporary people with dogs describe their pet as part of the family, although some ambivalence about the relationship is evident in the popular reconceptualization of the dog–human family as a pack. A model of dog–human relationships has been promoted by some dog trainers, such as on the television program. However it has been disputed that 'trying to achieve status' is characteristic of dog–human interactions. Pet dogs play an active role in family life; for example, a study of conversations in dog–human families showed how family members use the dog as a resource, talking to the dog, or talking through the dog, to mediate their interactions with each other. Increasingly, human family members are engaging in activities centered on the perceived needs and interests of the dog, or in which the dog is an integral partner, such as and.
According to statistics published by the in the National Pet Owner Survey in 2009–2010, it is estimated there are 77.5 million people with pet dogs in the United States. The same survey shows nearly 40% of American households own at least one dog, of which 67% own just one dog, 25% two dogs and nearly 9% more than two dogs. There does not seem to be any gender preference among dogs as pets, as the statistical data reveal an equal number of female and male dog pets. Yet, although several programs are ongoing to promote, less than a fifth of the owned dogs come from a shelter.
The latest study using (MRI) comparing humans and dogs showed that dogs have same response to voices and use the same parts of the brain as humans do. This gives dogs the ability to recognize emotional human sounds, making them friendly social pets to humans. Work Dogs have lived and worked with humans in so many roles that they have earned the unique nickname, 'man's best friend', a phrase used in other languages as well.
They have been bred for herding livestock, hunting (e.g. Pointers and hounds), rodent control, guarding, helping fishermen with nets,, and pulling loads, in addition to their roles as companions.
In 1957, a husky-terrier mix named became the first animal to orbit the. Such as, utility dogs, assistance dogs, hearing dogs, and psychological therapy dogs provide assistance to individuals with physical or mental disabilities. Some dogs owned by epileptics have been shown to alert their handler when the handler shows signs of an impending seizure, sometimes well in advance of onset, allowing the guardian to seek safety, medication, or medical care. Dogs included in human activities in terms of helping out humans are usually called. Sports and shows. Dogs come in a range of sizes.
People often enter their dogs in competitions such as breed-conformation shows or, including racing, sledding and agility competitions. In conformation shows, also referred to as breed shows, a judge familiar with the specific dog breed evaluates individual purebred dogs for conformity with their established breed type as described in the breed standard. As the breed standard only deals with the externally observable qualities of the dog (such as appearance, movement, and temperament), separately tested qualities (such as ability or health) are not part of the judging in conformation shows. Gaegogi (dog meat) stew being served in a Korean restaurant Dog meat is consumed in some countries, including, and, a practice that dates back to antiquity. It is estimated that 13–16 million dogs are killed and consumed in Asia every year.
Other cultures, such as and, also consumed dog meat in their history. However, Western, South Asian, African, and Middle Eastern cultures, in general, regard consumption of dog meat as. In some places, however, such as in rural areas of Poland, dog fat is believed to have medicinal properties—being good for the lungs for instance. Dog meat is also consumed in some parts of Switzerland. Proponents of eating dog meat have argued that placing a distinction between livestock and dogs is western hypocrisy, and that there is no difference with eating the meat of different animals. In Korea, the primary dog breed raised for meat, the (누렁이), differs from those breeds raised for pets that Koreans may keep in their homes. The most popular Korean dog dish is (also called bosintang), a spicy stew meant to balance the body's heat during the summer months; followers of the custom claim this is done to ensure good health by balancing one's, or vital energy of the body.
A 19th century version of gaejang-guk explains that the dish is prepared by boiling dog meat with and chili powder. Variations of the dish contain chicken and bamboo shoots. While the dishes are still popular in Korea with a segment of the population, dog is not as widely consumed as beef, chicken, and pork. Health risks to humans. Further information: In 2005, the reported that 55,000 people died in Asia and Africa from rabies, a disease for which dogs are the most important vector. Citing a 2008 study, the U.S. Estimated in 2015 that 4.5 million people in the USA are bitten by dogs each year.
A 2015 study estimated that 1.8% of the U.S. Population is bitten each year. In the 1980s and 1990s the US averaged 17 fatalities per year, while in the 2000s this has increased to 26. 77% of dog bites are from the pet of family or friends, and 50% of attacks occur on the property of the dog's legal owner. A study found bites in children were less severe than bites in adults. The incidence of dog bites in the US is 12.9 per 10,000 inhabitants, but for boys aged 5 to 9, the incidence rate is 60.7 per 10,000. Moreover, children have a much higher chance to be bitten in the face or neck.
Sharp claws with powerful muscles behind them can lacerate flesh in a scratch that can lead to serious infections. In the UK between 2003 and 2004, there were 5,868 on humans, resulting in 5,770 working days lost in sick leave. In the, and dogs are a factor in more than 86,000 falls each year. It has been estimated around 2% of dog-related injuries treated in UK hospitals are domestic accidents. The same study found that while dog involvement in road traffic accidents was difficult to quantify, dog-associated road accidents involving injury more commonly involved two-wheeled vehicles.
(dog ) eggs in dog feces can cause. In the United States, about 10,000 cases of Toxocara infection are reported in humans each year, and almost 14% of the U.S. Population is infected.
In Great Britain, 24% of soil samples taken from public parks contained T. [ ] Untreated toxocariasis can cause retinal damage and decreased vision. Dog feces can also contain that cause in humans. Health benefits for humans.
A human cuddles a puppy. The scientific evidence is mixed as to whether companionship of a dog can enhance human physical health and psychological wellbeing.
Studies suggesting that there are benefits to physical health and psychological wellbeing have been criticised for being poorly controlled, and finding that '[t]he health of elderly people is related to their health habits and social supports but not to their ownership of, or attachment to, a companion animal.' Earlier studies have shown that people who keep pet dogs or cats exhibit better mental and physical health than those who do not, making fewer visits to the doctor and being less likely to be on medication than non-guardians. A 2005 paper states 'recent research has failed to support earlier findings that pet ownership is associated with a reduced risk of cardiovascular disease, a reduced use of general practitioner services, or any psychological or physical benefits on health for community dwelling older people. Research has, however, pointed to significantly less absenteeism from school through sickness among children who live with pets.'
In one study, new guardians reported a highly significant reduction in minor health problems during the first month following pet acquisition, and this effect was sustained in those with dogs through to the end of the study. In addition, people with pet dogs took considerably more physical exercise than those with cats and those without pets.
The results provide evidence that keeping pets may have positive effects on human health and behaviour, and that for guardians of dogs these effects are relatively long-term. Pet guardianship has also been associated with increased coronary artery disease survival, with human guardians being significantly less likely to die within one year of an acute myocardial infarction than those who did not own dogs. The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the, can protect against allergies and autoimmune diseases.
The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners. The practice of using dogs and other animals as a part of therapy dates back to the late 18th century, when animals were introduced into mental institutions to help socialize patients with mental disorders.
Animal-assisted intervention research has shown that animal-assisted therapy with a dog can increase social behaviors, such as smiling and laughing, among people with Alzheimer's disease. One study demonstrated that children with ADHD and conduct disorders who participated in an education program with dogs and other animals showed increased attendance, increased knowledge and skill objectives, and decreased antisocial and violent behavior compared with those who were not in an animal-assisted program. Medical detection dogs Medical detection dogs are capable of detecting diseases by sniffing a person directly or samples of urine or other specimens.
Dogs can detect odour in one part per trillion, as their brain's olfactory cortex is (relative to total brain size) 40 times larger than humans. Dogs may have as many as 300 million odour receptors in their nose, while humans may have only 5 million. Each dog is trained specifically for the detection of single disease from the blood glucose level indicative to diabetes to cancer. The process of training a cancer dog requires six months. A called Daisy has detected 551 cancer patients with an accuracy of 93 percent and received the (for pets) Medal for her life-saving skills.
