Wolves are tolerant, attentive and cooperative and their relationship with pack mates could have provided the basis for today's human-dog relationship, a new study suggests. The origins of dog-human relationship were subject of a study by behavioural scientists from the Meserli Research Institute at the Vetmeduni Vienna and the Wolf Science Centre. They showed that the ancestors of dogs, the wolves, are at least as attentive to members of their species and to humans as dogs are. This social skill did not emerge during domestication, as has been suggested previously, but was already present in wolves, researchers said.
