Dogs were probably the first tame animals. They have accompanied humans for some 10,000 years. Some scientists assert that all dogs, domestic and wild, share a common ancestor in the small South Asian wolf. Although initially thought to have originated as a manmade variant of an extant canid species (variously supposed as being the dhole, golden jackal, or gray wolf, extensive genetic studies undertaken during the 2010s indicate that dogs diverged from other wolf-like canids in Eurasia 40,000 years ago. Being the oldest domesticated animals, their long association with people has allowed dogs to be uniquely attuned to human behavior, as well as thrive on a starch-rich diet which would be inadequate for other canid species.
The average life span of dogs vary with their breeds but majority of dogs life lies in between 11 to 14 years.Some breeds have short live span lies between 2 to 5 years maximum but some long lived breeds live more than 14 years.On Guinness Book of world records dog named Pusuke lived 26 years and 9 months longest life of dog so far recorded.
