The origin of the domestic dog includes the dog's genetic divergence from the wolf, its domestication, and the emergence of the first dogs.Genetic studies show that all ancient and modern dogs share a common ancestry and descended from an ancient, now-extinct wolf population - or closely related wolf populations - which was distinct from the modern wolf lineage. The main reason that dogs now-a-days - both feral and domesticated - are able to survive so well in the wild is because they're historically linked to wild dogs, like the small South Asian Wolf. Sometimes the dog will not be able to move at all and have total Paralysis, while other times your dog may only appear weak, or have difficulty moving.

Dogs, more so than almost any other domesticated species, are desperate for human eye contact. Humans also deliberately bred Dogs to be more adorable. Some argue that humans adopted wolf pups and that natural selection favored those less aggressive and better at begging for food.
