81-652: Nipper (1884 – September 1895), also known as the RCA Victor dog , was a dog from Bristol , UK. Bred as a terrier mix, he served as the model for a 1898 painting by British painter Francis Barraud titled His Master's Voice . This image has become one of the world's best known trademarks , the famous dog-and- gramophone pairing that has been used by several record companies and their associated company brands, including Berliner Gramophone and its various affiliates and successors, among them Berliner's German subsidiary Deutsche Grammophon ; Berliner's American successor
162-482: A cylinder phonograph . In early 1899, Francis Barraud applied for copyright of the original painting using the descriptive working title Dog looking at and listening to a Phonograph . He was unable to sell the work to any cylinder phonograph company. The painting had been originally offered to James Hough, manager of Edison-Bell in London, but he declined, saying "dogs don't listen to phonographs". William Barry Owen,
243-404: A "difference in motivation" between wolves and dogs. Some puppies and dogs engage in coprophagy out of habit, stress, for attention, or boredom; most of them will not do it later in life. A study hypothesizes that the behavior was inherited from wolves, a behavior likely evolved to lessen the presence of intestinal parasites in dens. Most dogs can swim. In a study of 412 dogs, around 36.5% of
324-468: A 2024 UK study analyzing 584,734 dogs, it was concluded that purebred dogs lived longer than crossbred dogs, challenging the previous notion of the latter having the higher life expectancies. The authors noted that their study included " designer dogs " as crossbred and that purebred dogs were typically given better care than their crossbred counterparts, which likely influenced the outcome of the study. Other studies also show that fully mongrel dogs live about

On 10 March 2010, a small road near to the dog's final resting place in Kingston upon Thames was officially named Nipper Alley in commemoration of this well-known resident. In 1898, three years after Nipper's death, Francis Barraud , the brother of Nipper's original owner, painted a picture of the dog listening intently to an Edison-Bell cylinder phonograph . Thinking

Their personality traits include hypersocial behavior, boldness, and aggression. Present-day dogs are dispersed around the world. An example of this dispersal is the numerous modern breeds of European lineage during the Victorian era. Dogs are extremely variable in size, ranging from one of
567-644: A control method for overpopulation. Neutering often occurs as early as 6–14 weeks in shelters in the US. The American Society for the Prevention of Cruelty to Animals (ASPCA) advises that dogs not intended for further breeding should be neutered so that they do not have undesired puppies that may later be euthanized. However, the Society for Theriogenology and the American College of Theriogenologists made
648-636: A joint statement that opposes mandatory neutering; they said that the cause of overpopulation in the US is cultural. Neutering is less common in most European countries, especially in Nordic countries —except for the UK, where it is common. In Norway, neutering is illegal unless for the benefit of the animal's health (e.g., ovariohysterectomy in case of ovarian or uterine neoplasia). Some European countries have similar laws to Norway, but their wording either explicitly allows for neutering for controlling reproduction or it
729-499: A natural instinct called prey drive (the term is chiefly used to describe training dogs ' habits) which can be influenced by breeding. These instincts can drive dogs to consider objects or other animals to be prey or drive possessive behavior. These traits have been enhanced in some breeds so that they may be used to hunt and kill vermin or other pests. Puppies or dogs sometimes bury food underground . One study found that wolves outperformed dogs in finding food caches, likely due to

They have difficulty differentiating between red and green, and much like other mammals, the dog's eye is composed of two types of cone cells compared to the human's three. The divergence of the eye axis of dogs ranges from 12 to 25°, depending on

Also called the domestic dog , it was selectively bred from an extinct population of wolves during the Late Pleistocene by hunter-gatherers . The dog was the first species to be domesticated by humans , over 14,000 years ago and before
1053-494: A set of social-cognitive abilities in domestic dogs that are not possessed by the dog's canine relatives or other highly intelligent mammals, such as great apes , are parallel to children's social-cognitive skills. Most domestic animals were initially bred for the production of goods. Dogs, on the other hand, were selectively bred for desirable behavioral traits. In 2016, a study found that only 11 fixed genes showed variation between wolves and dogs. These gene variations indicate
1134-458: A study of Boxer litters, 22% of puppies died before reaching 7 weeks of age. Stillbirth was the most frequent cause of death, followed by infection. Mortality due to infection increased significantly with increases in inbreeding. Dog behavior has been shaped by millennia of contact with humans. They have acquired the ability to understand and communicate with humans and are uniquely attuned to human behaviors. Behavioral scientists suggest that
1215-536: A study of seven dog breeds (the Bernese Mountain Dog , Basset Hound , Cairn Terrier , Brittany , German Shepherd Dog , Leonberger , and West Highland White Terrier ), it was found that inbreeding decreases litter size and survival. Another analysis of data on 42,855 Dachshund litters found that as the inbreeding coefficient increased, litter size decreased and the percentage of stillborn puppies increased, thus indicating inbreeding depression. In

Therefore, it did not assess them for the IUCN Red List of threatened species . The earliest remains generally accepted to be those of a domesticated dog were discovered in Bonn-Oberkassel , Germany. Contextual , isotopic , genetic , and morphological evidence shows that this dog

Furthermore, small dogs with longer muzzles have been shown to have higher lifespans than larger medium-sized dogs with much more depressed muzzles. For free-ranging dogs, less than 1 in 5 reach sexual maturity, and the median life expectancy for feral dogs is less than half of dogs living with humans. In domestic dogs, sexual maturity happens around six months to one year for both males and females, although this can be delayed until up to two years of age for some large breeds. This

The questions of when and where dogs were first domesticated remains uncertain. Genetic studies suggest a domestication process commencing over 25,000 years ago, in one or several wolf populations in either Europe,
1539-653: Is a notable genus with 5 species in which dogs are the definitive host . Additionally, dogs are a source of zoonoses for humans. They are responsible for 99% of rabies cases worldwide; however, in some developed countries such as the UK, rabies is absent from dogs and is instead only transmitted by bats. Other common zoonoses are hydatid disease , leptospirosis , pasteurellosis , ringworm , and toxocariasis . Common infections in dogs include canine adenovirus , canine distemper virus , canine parvovirus , leptospirosis , canine influenza , and canine coronavirus . All of these conditions have vaccines available. Dogs are

Germany forbids early age neutering, but neutering is still allowed at the usual age. In Romania, neutering is mandatory except for when a pedigree to select breeds can be shown. A common breeding practice for pet dogs is to mate them between close relatives (e.g., between half- and full-siblings). In

#17327731878221782-700: Is closely related to the ancestor of domestic dogs. In 2018, a study identified 429 genes that differed between modern dogs and modern wolves. As the differences in these genes could also be found in ancient dog fossils, these were regarded as being the result of the initial domestication and not from recent breed formation. These genes are linked to neural crest and central nervous system development. These genes affect embryogenesis and can confer tameness, smaller jaws, floppy ears, and diminished craniofacial development, which distinguish domesticated dogs from wolves and are considered to reflect domestication syndrome. The study concluded that during early dog domestication,

Dogs have roughly forty times more smell-sensitive receptors than humans, ranging from about 125 million to nearly 300 million in some dog breeds, such as bloodhounds . This sense of smell is the most prominent sense of the species; it detects chemical changes in the environment, allowing dogs to pinpoint

Evidence from veterinary practices and questionnaires showed that around 500 dogs would need to have their tail docked to prevent one injury. Numerous disorders have been known to affect dogs. Some are congenital and others are acquired. Dogs can acquire upper respiratory tract diseases including diseases that affect
2106-753: Is significant divergence in terms of skull shape between types. The three basic skull shapes are the elongated dolichocephalic type as seen in sighthounds , the intermediate mesocephalic or mesaticephalic type, and the very short and broad brachycephalic type exemplified by mastiff type skulls. The jaw contains around 42 teeth, and it has evolved for the consumption of flesh. Dogs use their carnassial teeth to cut food into bite-sized chunks, more especially meat. Dogs' senses include vision, hearing, smell, taste, touch, and magnetoreception . One study suggests that dogs can feel small variations in Earth's magnetic field . Dogs prefer to defecate with their spines aligned in

One of the primary functions of a dog's tail is to communicate their emotional state. The tail also helps the dog maintain balance by putting its weight on the opposite side of the dog's tilt, and it can also help the dog spread its anal gland 's scent through

Compared to the dog's wolf-like ancestors, selective breeding since domestication has seen the dog's skeleton increase in size for larger types such as mastiffs and miniaturised for smaller types such as terriers ; dwarfism has been selectively bred for some types where short legs are preferred, such as dachshunds and corgis . Most dogs naturally have 26 vertebrae in their tails, but some with naturally short tails have as few as three. The dog's skull has identical components regardless of breed type, but there

Most poisonings are accidental and over 80% of reports of exposure to the ASPCA animal poisoning hotline are due to oral exposure. The most common substances people report exposure to are: pharmaceuticals, toxic foods, and rodenticides . Data from the Pet Poison Helpline shows that human drugs are the most frequent cause of toxicosis death. The most common household products ingested are cleaning products. Most food related poisonings involved theobromine poisoning (chocolate). Other common food poisonings include xylitol , Vitis (grapes, raisins, etc.) and Allium (garlic, oninions, etc.). Pyrethrin insecticides were

They can pick up the slightest sounds from about 400 m (1,300 ft) compared to 90 m (300 ft) for humans. Dogs have stiff, deeply embedded hairs known as whiskers that sense atmospheric changes, vibrations, and objects not visible in low light conditions. The lower most part of whiskers hold more receptor cells than other hair types, which help in alerting dogs of objects that could collide with

These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response (i.e., selection for tameness ) and emotional processing. Compared to their wolf counterparts, dogs tend to be less timid and less aggressive, though some of these genes have been associated with aggression in certain dog breeds. Traits of high sociability and lack of fear in dogs may include genetic modifications related to Williams-Beuren syndrome in humans, which cause hypersociability at
5670-428: The painting. When Gramophone Company founder and manager William Barry Owen was shown the painting, he suggested that if the artist painted out the cylinder machine and replaced it with a Berliner disc gramophone , he would buy the painting.

5913-407: The right side". Dogs can injure themselves by wagging their tails forcefully; this condition is called kennel tail , happy tail , bleeding tail , or splitting tail . In some hunting dogs , the tail is traditionally docked to avoid injuries. Some dogs can be born without tails because of a DNA variant in the T gene , which can also result in a congenitally short (bobtail) tail. Tail docking
5994-644: The tail's position and movement. Dogs can have a violet gland (or supracaudal gland) characterized by sebaceous glands on the dorsal surface of their tails; in some breeds, it may be vestigial or absent. The enlargement of the violet gland in the tail, which can create a bald spot from hair loss , can be caused by Cushing's disease or an excess of sebum from androgens in the sebaceous glands. A study suggests that dogs show asymmetric tail-wagging responses to different emotive stimuli. "Stimuli that could be expected to elicit approach tendencies seem to be associated with [a] higher amplitude of tail-wagging movements to
6075-415: The tail), powerful jaws that house around 42 teeth, and well-developed senses of smell, hearing, and sight. Compared to humans, dogs have an inferior visual acuity , a superior sense of smell, and a relatively large olfactory cortex . They perform many roles for humans, such as hunting , herding , pulling loads , protection , companionship , therapy , aiding disabled people , and assisting police and
6156-610: The trademark and logo for their United States affiliate, the Victor Talking Machine Company in 1901.

The dog was dated to 14,223 years ago and was found buried along with a man and a woman, all three having been sprayed with red hematite powder and buried under large, thick basalt blocks. The dog had died of canine distemper . This timing indicates that the dog was the first species to be domesticated in the time of hunter-gatherers , which predates agriculture. Earlier remains dating back to 30,000 years ago have been described as Paleolithic dogs , but their status as dogs or wolves remains debated because considerable morphological diversity existed among wolves during
