Study explores differences in dog brains

It isn’t news to anybody that different breeds of dogs were bred for different functions. (Though there is a lot of variation within breeds, difference between breeds are considerable.) Nobody is surprised when a retriever loves to retrieve or a shepherd is a natural at herding. Dogs whose ancestors were bred for guarding, scent hunting, sight hunting or companionship have similarly predictable behavior in many cases. Though temperaments, behavior and cognitive abilities have been explored across breeds and breed groups, the neuroanatamincal (brain structure) basis of these differences has not been as well studied. A new research project investigated the links between brain structure and behavior.
