Origin of the domestic dog
The origin of the domestic dog is not clear. The domestic dog is a member of the genus "Canis", which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The closest living relative of the dog is the extant gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf are sister taxa as modern wolves are 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.
Dog
The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of the genus "Canis" (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. Their long association with humans 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.
Dmitry Belyayev (zoologist)
Dmitry Konstantinovich Belyayev (Russian: Дмитрий Константинович Беляев, 17 July 1917 – 14 November 1985) was a Russian geneticist and academician who served as director of the Institute of Cytology and Genetics (IC&G) of the USSR Academy of Sciences, Novosibirsk, from 1959 to 1985. His decades-long effort to breed domesticated foxes was described by "The New York Times" as “arguably the most extraordinary breeding experiment ever conducted.” A 2010 article in Scientific American stated that Belyayev “may be the man most responsible for our understanding of the process by which wolves were domesticated into our canine companions.”  Beginning in the 1950s, in order to uncover the genetic basis of the distinctive behavioral and physiological attributes of domesticated animals, Belyayev and his team spent decades breeding the wild silver fox ("Vulpes vulpes") and selecting for reproduction only those individuals in each generation that showed the least fear of humans.
Dingo
The dingo ("Canis lupus dingo" or "Canis dingo") is a type of feral dog native to Australia. The first British colonists to arrive in 1788 established a settlement at Port Jackson and recorded dingoes living there with indigenous Australians. Although the dingo exists in the wild, it associates with humans but has not been selectively bred similarly to other domesticated animals. It is a medium-sized canid that possesses a lean, hardy body designed for speed, agility and stamina. The dingo's three main coat colours are described as being either light ginger (or tan), black and tan, or creamy white.
Domestication of animals
The domestication of animals is the mutual relationship between animals with the humans who have influence on their care and reproduction. Charles Darwin recognized the small number of traits that made domesticated species different from their wild ancestors. He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits. There is a genetic difference between domestic and wild populations. There is also such a difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, and the improvement traits that have appeared since the split between wild and domestic populations.
Must Love Dogs
Must Love Dogs is a 2005 American romantic comedy film based on Claire Cook's 2002 novel of the same name. Starring Diane Lane and John Cusack, it is the second and final film directed and written by Gary David Goldberg and was produced on a budget of $30 million. The film focuses on a woman's struggle with divorce and meeting new people afterward. Production started on October 12, 2004 with a final release date of July 29, 2005. Critics opinions were mostly negative but indicated that the actors were not to blame. "Must Love Dogs" took the fifth spot on its opening weekend and has grossed more than $58 million worldwide.
Cattle
Cattle—colloquially cows—are the most common type of large domesticated ungulates. They are a prominent modern member of the subfamily Bovinae, are the most widespread species of the genus "Bos", and are most commonly classified collectively as Bos taurus. Cattle are commonly raised as livestock for meat (beef and veal), as dairy animals for milk and other dairy products, and as draft animals (oxen or bullocks that pull carts, plows and other implements). Other products include leather and dung for manure or fuel. In some regions, such as parts of India, cattle have significant religious meaning.

Dingo–dog hybrid
A dingo–dog hybrid is a cross between a dingo and a domestic dog. The current population of free ranging domestic dogs in Australia is now probably higher than in the past. However, the proportion of the so-called "pure" dingoes (dogs with exclusively dingo-ancestry) has been in the decrease over the last few decades due to hybridisation and is regarded as further decreasing. Because of this ongoing interbreeding of dingoes and other domestic dogs and the resulting hybrids, there is a much wider range of colours and body shapes today among the Australian wild dog population than in the time before the human introduction of domestic dogs.

New Guinea singing dog
The New Guinea singing dog or New Guinea Highland dog ("Canis lupus dingo") is a type of dog native to the New Guinea Highlands of the island of New Guinea. The dog is noted for its unique vocalization. Some experts have referred to it as a wild dog, but others disagree. Little is known about New Guinea singing dogs in the wild and there are only two photographs of wild sightings: one taken in 1989 and published by Australian mammalogist Tim Flannery, and the other taken in August 2012 by wilderness adventure guide, Tom Hewett in the Star Mountains region of West Papua. In 2016, the New Guinea Highland Wild Dog Foundation announced to the media that it and the University of Papua had located and photographed a group of fifteen "highland wild dogs".

Wolfdog
A wolfdog (also called a wolf–dog hybrid or wolf hybrid) is a canid hybrid resulting from the hybridization of a domestic dog ("Canis lupus familiaris") to one of four other "Canis" sub-species, the gray ("Canis lupus"), eastern timber ("Canis lycaon"), red ("Canis rufus"), and Ethiopian wolves ("Canis simensis"). Intra-hybridization between dogs and other subspecies of gray wolves are the most common wolfdogs since dogs and gray wolves are considered the same species, are genetically very close, and have shared vast portions of their ranges for millennia. Such hybridization in the wild have been detected in many populations scattered throughout Europe and North America, usually occurring in areas where wolf populations have declined from human impacts and persecutions.
African wild dog
The African wild dog ("Lycaon pictus"), also known as African hunting dog, African painted dog, painted hunting dog or painted wolf, is a canid native to Sub-Saharan Africa. It is the largest of its family in Africa, and the only extant member of the genus "Lycaon", which is distinguished from "Canis" by its fewer toes and its dentition, which is highly specialised for a hypercarnivorous diet. It is classified as endangered by the IUCN, as it has disappeared from much of its original range. The current population has been estimated at roughly 39 subpopulations containing 6,600 adults, only 1,400 of which are fully grown.

I love them! They are the greatest! How long do dogs typically live?
0_Wizard
Life spans vary according to breed and size with the larger dogs living shorter life spans, oddly. Ten years is tops for the large breeds usually.

Dog health
The health of dogs is a well studied area in veterinary medicine. Infectious diseases that affect dogs are important not only from a veterinary standpoint, but also because of the risk to public health; an example of this is rabies. Genetic disorders also affect dogs, often due to selective breeding to produce individual dog breeds. Due to the popularity of both commercial and homemade dog foods, nutrition is also a heavily studied subject. Some diseases and other health problems are common to both humans and dogs; others are unique to dogs and other animals. Dogs are susceptible to various diseases; similarly to humans, they can have diabetes, epilepsy, cancer, or arthritis.
Gray wolf
The gray wolf ("Canis lupus"), also known as the timber wolf or western wolf, is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging and females . Like the red wolf, it is distinguished from other "Canis" species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy and predominantly a mottled gray in color, although nearly pure white, red, and brown to black also occur. "Mammal Species of the World" (3rd ed., 2005), a standard reference work in zoology, recognises 38 subspecies of "C. lupus"..Gray wolfs are pack hunters.
St. Bernard (dog)
The St. Bernard or St Bernard ( or ) is a breed of very large working dog from the western Alps in Switzerland, France and Italy. They were originally bred at the Great and Little St Bernard Pass for rescue. The breed has become famous through tales of alpine rescues, as well as for its enormous size. The St. Bernard is a giant dog. The average weight of the breed is between or more, and the approximate height at the withers is . The coat can be either smooth or rough; the smooth coat being close and flat while the rough is dense, flat, and more profuse around the neck and legs. The colour is typically a red shade with white, or a mahogany brindle with white.
Tibetan Mastiff
The Tibetan Mastiff is a large Tibetan dog breed ("Canis lupus familiaris"). Originating with the nomadic cultures of Tibet, China, India, Mongolia and Nepal, it is used by local tribes of Tibetans to protect sheep from wolves, leopards, bears, large mustelids, and tigers. The Tibetan Mastiff known as "Drog-Khyi" (འབྲོག་ཁྱི) in Tibetan, which means "nomad dog", ("dog which may be tied", "dog which may be kept"), reflects its use as a guardian of herds, flocks, tents, villages, monasteries, and palaces, much as the old English ban-dog (also meaning tied dog) was a dog tied outside the home as a guardian.

Cavalier King Charles Spaniel
The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club. It originated in the United Kingdom and is one of the more popular breeds in many countries. Since 2000, it has grown in popularity in the United States and ranks as the 18th most popular pure-breed in the United States (2013 Registration Statistics). It has a silky, smooth coat and commonly a smooth undocked tail. The breed standard recognizes four colours: Blenheim (chestnut and white), Tricolor (black/white/tan), Black and Tan, and Ruby. The breed is generally friendly, affectionate and good with both children and other animals; however, they require a lot of human interaction.
