'Friendly' dog genes found

New Delhi, Sep 15 (ANI): The United States researchers have identified a genetic difference between dogs and wolves that could explain why dogs are so friendly. Behavioral studies run by animal behaviorist showed that pet domestic dogs are more sociable and less afraid of strangers than wolves, even when those wolves were raised by humans. The researchers say the results of the study could help explain how wild wolves domesticated by prehistoric humans turned into the face-licking, tail-wagging dogs of today.
