Hound is the name of a group of dogs. Hounds are of two types: those that hunt by following the scent of their quarry, and those that hunt by sight. Scent hounds include the foxhound, coonhound, beagle, bloodhound, basset hound, and dachshund. Among sight hounds are the greyhound, afghan, borzoi, Scottish deerhound, saluki, and Irish wolfhound. The typical hound has long ears, strong legs, and a long tail. Hounds are alert, love the outdoors, and have great endurance. They are among the oldest known dogs.
