Why are dogs our best friends?

Dogs move tails, lick our hands and faces, throw us in the embrace. Is it possible not to love them? It's hard! But the real question is why dogs have become such good friends.

Dog association is easy to see and undoubtedly sincere. Why do dogs love people so much?

A group of scientists who work at the state University of Oregon have discovered that dogs have a genetic predisposition to love people, but the basis is that the same thing in humans causes disease known as Williams-Beuren syndrome.

This is obviously logical, considering that symptoms of this syndrome involve intensive association.

Research author Bridget M. VonHold is an evolutionary biologist and hopes one day he will strongly confirm what genes have to do with behavior.

The study is conducted in dogs and wolves, which show the possible level from one species to another, however, is a step in the right direction.
