The hounds are one the oldest groups of dogs, aiding humans by pursuing and catching their quarry. The sighthounds pursue by sight and include the fast-running dogs of greyhound build, whereas the scenthounds pursue by scent and include the more solidly built dogs of general foxhound build. Some breeds hunt by both sight and scent, and a few breeds don't seem like hounds at all. Again, all hound breeds have in common the independent pursuit of mammalian quarry. As such, they traditionally could not wait for the hunter's direction; they led the way.
