Dog breeds are usually grouped—often arbitrarily or erroneously—into from five to ten categories based on function, superficial appearance, or geographical origin, depending on the registry organization. Just because it may make more sense to assign them to groups based primarily on ancestry and then on historical function, does not mean that such will be the case. In most dog circles, the “working” breeds have always been considered as those that originally did such work as herding or guarding livestock, pulling loads, and protecting property. Even though other breeds had specific occupations in the service of man, they are not known as working breeds: sighthounds running down prey or predators, gundogs flushing food for the table, terriers and toys terrorizing vermin — these were more or less doing what they would do without human ownership, anyway, so their jobs were considered less like “work.”
Many dog organizations split the huge Working Group into two, with the ones that had historical development for tending, driving, or bunching flocks and herds being called “Herding breeds.” Never mind the confusion about whether the reindeer-herding Samoyed is hardly much different from the sled-pulling Husky—that’s a puzzle for another time. Most of the Group that did not resemble the mastino-type wagon puller or the bear-fighting wooly flock guardian type were once employed to trot around the animals raised by man for his food, and assigned to the herding subcategory. These latter were specialists in trotting, in covering much ground with the most efficiency (least effort). This meant that success favored those with the most shoulder angulation over those with the stiffer, more vertical front ends.
