dogs

the domestic dog is a subspecies of the gray wolf. the term "domestic dog" is generally used for both domesticated and feral varieties. the dog may have been the first animal to be domesticated, and has been the most widely kept working, hunting, and pet animal in human history. dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. this impact on human society has given them the nickname "man's best friend" in the western world.most breeds of dogs are at most a few hundred years old, having been artificially selected for particular morphologies and behaviors by people for specific functional roles. through this selective breeding, the dog has developed into hundreds of varied breeds.
