Structure in Action - Tapa blanda

Many people probably think that all the fuss that breeders and fanciers make over their purebred dogs—how they look, how they move—is unnecessary. Why do the teeth need to be just so? Why does a judge do such a thorough hands-on evaluation of twenty dogs that to most of us look so much alike? The answer lies in the fact that purebred dogs are bred for a specific purpose and that the structure of the dog impacts its ability to do what it has been bred for be it retrieving game, guarding livestock, tracking lost people, or pulling sleds full of supplies to a snowed-in village.
