I love dogs. In fact, I have three of them. Dogs were domesticated before any other animal and have been selectively bred ever since.
The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.

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.
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.
Selective breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, or cultivars. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals.
Landrace
A landrace is a domesticated, locally adapted, traditional variety of a species of animal or plant that has developed over time, through adaptation to its natural and cultural environment of agriculture and pastoralism, and due to isolation from other populations of the species. Landraces are generally distinguished from cultivars, and from breeds in the standardized sense, although the term landrace breed is sometimes used as distinguished from the term "standardized breed" when referring to cattle. The "-race" in this word refers to the taxonomic definition of "race" in biology, not the ethnographic sense of the word.
Sled dog
Sled dogs were important for transportation in arctic areas, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska and northern Canada. Sled dogs today are still used by some rural communities, especially in areas of Alaska and Canada and throughout Greenland. They are used for recreational purposes and racing events, such as the Iditarod Trail and the Yukon Quest. Sled dogs have been used in Canada, Lapland, Greenland, Siberia, Chukotka, Norway, Finland, and Alaska.

It's not clear, though the gray wolf is the dog's closest living relative.
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.

Evolution of the wolf
The evolution of the wolf occurred over a geologic time scale of 800 thousand years, transforming the first Middle Pleistocene wolf specimen that is recognized as being morphologically similar to "Canis lupus" into today's dog, dingo and gray wolf. Ecological factors including habitat type, climate, prey specialization and predatory competition has greatly influenced the wolf's genetic population structure and cranio-dental plasticity. Wolves went through a population bottleneck 20,000 years before present (YBP), which indicates that many wolf populations had gone extinct at a time that coincided with the Last Glacial Maximum and the expansion of modern humans worldwide with their technology for capturing large game.

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.

Dire wolf
The dire wolf ("Canis dirus", "fearsome dog") is an extinct species of the genus "Canis". It is one of the most famous prehistoric carnivores in North America, along with its extinct competitor, the sabre-toothed cat "Smilodon fatalis". The dire wolf lived in the Americas during the Late Pleistocene epoch (125,000–10,000 years ago). The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized, these being "Canis dirus guildayi" and "Canis dirus dirus". The dire wolf probably evolved from Armbruster's wolf ("Canis armbrusteri") in North America.
Red wolf
The red wolf ("Canis rufus" or "Canis lupus rufus"), also known as the Florida black wolf or Mississippi Valley wolf, is a canid of unresolved taxonomic identity native to the eastern United States. It is generally, morphologically, an intermediate between the coyote and gray wolf, and is of a reddish, tawny color. The Red Wolf is a federally listed endangered species of the United States, and is protected by law. It has been listed by IUCN as a critically endangered species since 1996. It is considered the rarest species of wolf and is one of the five most endangered species of wolf in the world.
Eastern wolf
The eastern wolf ("Canis lycaon" or "Canis lupus lycaon"), also known as the eastern timber wolf, Algonquin wolf or deer wolf, is a canid native to the northeastern side of North America's Great Lakes region. It is a medium-sized canid which, like the red wolf, is intermediate in size between the coyote and the gray wolf. It primarily preys on white-tailed deer, but may occasionally attack moose and beaver. The eastern wolf's taxonomic classification has been under review beginning c. 2000, with various suggestions having been presented as to its derivation, including its being a subspecies of gray wolf, its being conspecific with the red wolf, gray wolf–coyote hybridization, and classification as a separate species within "Canis".

How far back does can one trace the history of man living with dogs?
0_Wizard
Depends on who you ask. Some say evidence points to 14,700 years ago, and some as far back as 36,000 years.
The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago, with disputed remains occurring 36,000 years ago.

Early human migrations
The earliest migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of "Homo erectus", followed by other archaic humans including "H. heidelbergensis", the likely ancestor of both anatomically modern humans and Neanderthals, around 500,000 years ago. Within Africa, "Homo sapiens" diverged around the time of its speciation, roughly 300,000 years ago. The "recent African origin" paradigm suggests that the anatomically modern humans outside of Africa descend from a population of "Homo sapiens" migrating from East Africa after roughly 70,000 years ago and spread along the southern coast of Asia and to Oceania before 50,000 years ago.
Human evolution
Human evolution is the evolutionary process that led to the emergence of anatomically modern humans, beginning with the evolutionary history of primates – in particular genus "Homo" – and leading to the emergence of "Homo sapiens" as a distinct species of the hominid family, the great apes. This process involved the gradual development of traits such as human bipedalism and language. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, neurobiology, ethology, linguistics, evolutionary psychology, embryology and genetics.
Newberry Volcano
Newberry Volcano (also known as Newberry Caldera) is a large active shield-shaped stratovolcano located east of the major crest of the Cascade Range and about south of Bend, Oregon, within the Newberry National Volcanic Monument. The largest volcano in the Cascade Volcanic Arc, it has roughly the same area as the state of Rhode Island at when its lava flows are taken into account. From its northernmost to southernmost point, the volcano is in length, with a width of and a total volume of approximately . It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855, and the area surrounding the volcano has been inhabited by Native American populations for more than 10,000 years.
Recent African origin of modern humans
The recent African origin of modern humans, also called the "Out of Africa" theory (OOA), recent single-origin hypothesis (RSOH), replacement hypothesis, or recent African origin model (RAO), is, in paleoanthropology, the dominant model of the geographic origin and early migration of anatomically modern humans ("Homo sapiens"). The model proposes a single area of origin for modern humans. The "single-origin hypothesis" is cited as having scientific consensus as of the mid-2000s. According to this model, modern humans evolved in East Africa between 400,000 and 200,000 years ago. There were then at least two dispersal events from Africa to the rest of the world.
Mono–Inyo Craters
The Mono–Inyo Craters are a volcanic chain of craters, domes and lava flows in Mono County, Eastern California. The chain stretches from the northwest shore of Mono Lake to the south of Mammoth Mountain. The Mono Lake Volcanic Field forms the northernmost part of the chain and consists of two volcanic islands in the lake and one cinder cone volcano on its northwest shore. Most of the Mono Craters, which make up the bulk of the northern part of the Mono–Inyo chain, are phreatic (steam explosion) volcanoes that have since been either plugged or over-topped by rhyolite domes and lava flows. The Inyo Craters form much of the southern part of the chain and consist of phreatic explosion pits, and rhyolitic lava flows and domes.
Genetic history of Europe
The genetic history of Europe encompasses the history of the patterns of genetic diversity among the human populations of the European continent. The history reflects the patterns of demographic and ethnic changes that have occurred in Europe throughout time. The primary data comes from sequences of mitochondrial, Y-chromosome and autosomal DNA (including single-nucleotide polymorphisms), from modern populations and, where available, from ancient DNA. One of the first scholars to perform genetic studies was Luigi Luca Cavalli-Sforza. He used classical genetic markers to analyse DNA by proxy. This method studies differences in the frequencies of particular allelic traits, namely polymorphisms from proteins found within human blood (such as the ABO blood groups, Rhesus blood antigens, HLA loci, immunoglobulins, G6PD isoenzymes, among others).
Prehistoric art
In the history of art, prehistoric art is all art produced in preliterate, prehistorical cultures beginning somewhere in very late geological history, and generally continuing until that culture either develops writing or other methods of record-keeping, or makes significant contact with another culture that has, and that makes some record of major historical events. At this point ancient art begins, for the older literate cultures. The end-date for what is covered by the term thus varies greatly between different parts of the world. The earliest human artifacts showing evidence of workmanship with an artistic purpose are the subject of some debate.
