Hound isn't one breed but a family of hunting dogs. Scent hounds such as Beagles, Coonhounds and Foxhounds follow a trail with their noses, while sighthounds such as Greyhounds and Whippets chase what they see. On adoption listings, the label usually means a scent-hound mix with long ears, a short coat and a loud voice, typically between 20 and 70 pounds.
Most hounds are sociable, easygoing dogs that enjoy company. They can also be stubborn, howl or bay, and wander off when a scent grabs them. Because ancestry varies so much, the size, energy and voice described in each listing say more about a dog than the hound label does, and each dog will show these traits differently.
