Domestic breed of dogs is a product of ancient humans domesticating wild wolves who hung around for scraps of meat and bones leftovers from a hunt. Selective breeding over 15,000 years has produced a variety of dog breeds who look so different. But the pack characteristics in their genes carries on, which include loyalty to death for the pack and subservience to the alpha male, which now is replaced by dog’s human owner.
I read or heard someplace that if all dog breeds were allowed to breed freely they would all end up looking alike after some years-——similar to Dingoes and Wild Dogs of Africa.
