Breeds and behavior

Breed matters: A dog that stares down invisible prey or slowly stalks other dogs may be presenting very good "eye" behavior for a herder. So too with the dog who is aggrieved when one person leaves the room or who nips at everyone's heels as they wander down the hallway. Freezing at movement in the bushes slows down your walk, but it is very good pointing behavior. . . . Give your dog a context to play out his innate tendencies—and indulge him a little staring at the bushes now and then.
