The frontal lobes and brain regions associated with social behaviour are proportionally larger in dogs than in wolves,the Natural History Museum said. These areas are also more pronounced in particularly "co-operative" breeds than in independent breeds. The researchers conclude the extent to which human selection has influenced the brain development and composition of dogs. However, genetic factors could also play a role. For example, "old" breeds such as the Siberian Husky would have a more wolf-like neuroanatomy than modern breeds such as the German Shepherd. Small brains, great adaptability According to the press release, dogs have smaller brains compared to wolves, but with more differences in shape ...
