Domestication has not made dogs cooperate more with each other compared to wolves
Following domestication, dogs should be more tolerant and cooperative with conspecifics and humans compared to wolves.

Researchers now show that the wild ancestors are excelling their domesticated relatives in teamwork. In an experimental approach dogs but not wolves failed to cooperatively pull the two ends of a rope to obtain a piece of food.
