Hound is a label for a big family of hunting dogs rather than one breed. Scent hounds like Beagles, Coonhounds and Foxhounds follow a trail by nose, while sighthounds such as Greyhounds and Whippets chase by sight. A hound on an adoption listing is usually a scent-hound mix with long ears, a short coat and a voice that carries, and size can run from about 20 to 70 pounds.
Most hounds are friendly with people and other dogs, and they're happiest with a nose to the ground. They can also be stubborn, wander after a scent and howl or bay. In Brockton, that makes a six-foot leash and a secure fence more than a suggestion. Dogs vary a lot, so the size, energy and voice described on each listing say more than the label does.
