 The wolf puppies were rarely seen as being aggressive to each other or towards the other canines.On the other hand, the dog puppies were much more aggressive to each other and other canines, often seen full-on attacking their foster mother or one another.Despite claims that dogs show more human-like social cognition than wolves, several recent studies have demonstrated that if wolves are properly socialized to humans and have the opportunity to interact with humans regularly, then they too can succeed on some human-guided cognitive tasks, in some cases out-performing dogs at an individual level.
