The genetic divergence between dogs and wolves occurred between 40,000–20,000 years ago, just before or during the Last Glacial Maximum.[27][2] This timespan represents the upper time-limit for the commencement of domestication because it is the time of divergence and not the time of domestication, which occurred later.[27][28] The domestication of animals commenced over 15,000 years ago, beginning with the grey wolf (Canis lupus) by nomadic hunter-gatherers.[27] The archaeological record and genetic analysis show the remains of the Bonn–Oberkassel dog buried beside humans 14,200 years ago to be the first undisputed dog, with disputed remains occurring 36,000 years ago.[2] It was not until 11,000 years ago that people living in the Near East entered into relationships with wild populations of aurochs, boar, sheep, and goats.[27]
Unlike other domestic species which were primarily selected for production-related traits, dogs were initially selected for their behaviors.[96][97] 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 catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight response[97][98] (i.e. selection for tameness), and emotional processing.[97] Dogs generally show reduced fear and aggression compared with wolves.[97][99] 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.[97] 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 the expense of problem solving ability.[100][101][102]

In mythology, dogs often serve as pets or as watchdogs.[208] Stories of dogs guarding the gates of the underworld recur throughout Indo-European mythologies[210][211] and may originate from Proto-Indo-European religion.[210][211] In Greek mythology, Cerberus is a three-headed watchdog who guards the gates of Hades.[208] In Norse mythology, a bloody, four-eyed dog called Garmr guards Helheim.[208] In Persian mythology, two four-eyed dogs guard the Chinvat Bridge.[208] In Welsh mythology, Annwn is guarded by Cŵn Annwn.[208] In Hindu mythology, Yama, the god of death, owns two watch dogs who have four eyes. They are said to watch over the gates of Naraka.[212]
Decide if you need to clip your dog's coat. Many breeds have short hair and don't require regular clipping. However, if you have a shaggier breed of dog, he may require regular clipping as part of his health routine. Breeds that need regular coat trims include cocker spaniel, sheepdog, poodle, collie, Shih Tzu, Pekingese, and chow chow, among others.[7]
Dogs have been described as carnivores[117][118] or omnivores.[17][119][120][121] Compared to wolves, dogs have genes involved in starch digestion that contribute to an increased ability to thrive on a starch-rich diet.[19] Based on metabolism and nutrition, many consider the dog to be an omnivore. However, the dog is not simply an omnivore. More like the cat and less like other omnivores, the dog can only produce bile acid with taurine, and it cannot produce vitamin D, which it obtains from animal flesh. Also more like the cat, the dog requires arginine to maintain its nitrogen balance. These nutritional requirements place the dog part-way between carnivores and omnivores.[122]
Long fur on the paws acts as a trap for grass seeds, grit, or even ice, so regular trimming is advisable. Use a pair of curved scissors with rounded tips. Work on one toe at a time and twirl the fur growing between two toes between your finger and thumb, and then snip the hair off at the base. Be careful never to pull on the fur, which elevates the skin and makes cutting it more likely. If you cannot see where the skin ends and the fur starts, then slide a comb through the fur at skin level, and using the scissors cut on the safe side of the comb. Repeat for each toe on each paw.
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.[197] Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, 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.[198] 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.[199] In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.[200]

Take extra care with dark-nailed dogs not to clip to the quick (blood vessel). Go slowly, and only take a little bit off at a time. Dremeling is much safer and easier to avoid hitting the quick, as it shaves only a little bit at a time. Use a cordless pet-safe Dremel tool, as the corded ones will not stop turning if they catch hair. Don't dremel for too long as it will burn the nail and prolong the trimming process for the dog which causes more stress. The best recommended process is trim first then dremel to shorten a little bit and round out the nail do it's not sharp.
In 2013, an estimate of the global dog population was 987 million.[104] Although it is said that the "dog is man's best friend",[105] this refers largely to the ~20% of dogs that live in developed countries. In the developing world, dogs are more commonly feral or communally owned, with pet dogs uncommon.[50] 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 (11%).[106] Little is known about these dogs, or the dogs in developed countries that are feral, stray or are in shelters, because the great majority of modern research on dog cognition has focused on pet dogs living in human homes.[107]
Human emigrants from Siberia that came across the Bering land bridge into North America likely had dogs in their company. Although one writer[139] even suggests that the use of sled dogs may have been critical to the success of the waves that entered North America roughly 12,000 years ago,[139] the earliest archaeological evidence of dog-like canids in North America dates from about 9,400 years ago.[132]:104[140] Dogs were an important part of life for the Athabascan population in North America, and were their only domesticated animal. Dogs as pack animals may have contributed migration of the Apache and Navajo tribes 1,400 years ago. This use of dogs in these cultures often persisted after the introduction of the horse to North America.[141]
Dogs demonstrate a theory of mind by engaging in deception[89]. An experimental study showed compelling evidence that Australian dingos 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.[90] 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.[91] Modern domestic dogs use humans to solve their problems for them.[92][93]

Be patient. You may have to go over your dog's coat a few times before you have a smooth, even cut. Don't rush it! Give your dog as many breaks as necessary, and make sure to move your clippers slowly. Brushing up against the coat then going the spot with clippers again help to get a smooth cut. Do will have to be done many times before you are done.
