Wolves kill dogs wherever they are found together.[111] One study reported that in Wisconsin in 1999 more compensation had been paid for losses due to wolves taking dogs than for wolves taking livestock. In Wisconsin wolves will often kill hunting dogs, possibly because the dogs are in the wolf's territory.[111] A strategy has been reported in Russia where one wolf lures a dog into heavy brush where another wolf waits in ambush.[112] 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.[113] Although the numbers of dogs killed each year are relatively low, it induces a fear of wolves entering villages and farmyards to take dogs, and losses of dogs to wolves has led to demands for more liberal wolf hunting regulations.[108]
The domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species)[5] is a member of the genus Canis (canines), which forms part of the wolf-like canids,[6] and is the most widely abundant terrestrial carnivore.[7][8][9][10][11] The dog and the extant gray wolf are sister taxa[12][13][14] as modern wolves are not closely related to the wolves that were first domesticated,[13][14] which implies that the direct ancestor of the dog is extinct.[15] The dog was the first species to be domesticated[14][16] and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.[17]

Cut out mats that can't be brushed out. Severe matting can pull the skin every time the dog moves, making daily life painful for your pet. If you can't brush a mat out, you need to either cut or shave it off, depending on how close it is to the skin. Be extremely careful if you use scissors to avoid injuring yourself or your pet. Try to cut parallel to the growth of the hair to avoid a choppy look.

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]
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]
You may need to pluck ear hairs from time to time. Ask a veterinarian or professional groomer to show you how to pluck the hairs from your dog's ear safely and correctly. Ear powder makes the process easier and quicker by giving added gripping power to the slippery ear hairs. Be very careful when using hemostats as they may poke inside their ear if used incorrectly or when the dog jerks their head.
There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries.[38] In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.[39]
