The AKC (American Kennel Club), and indeed, every National Kennel Club and dog registry, classifies each dog breed based on its original function. This is a list of the Hound Group - dogs with a superior sense of smell, or sight, and instincts to take it after game in a hunt.
Afghan HoundLike the name implies, the Afghan Hound calls Afghanistan its home. Its tall, slender frame covered with silky long fur is easily recognized as one of today's most graceful and elegant sighthounds. A sensitive dog that requires constant grooming to keep that silky coat from matting, the Afghan Hound does make a fantastic companion, but also needs to have an owner familiar with the capriciousness of independant thinking dogs. Fairly good with children, and content with apartment life, as long as provided with regular vigorous exercise.
American FoxhoundTaller and leaner-looking than the English Foxhound, the American Foxhound is still used for fox hunting today. The American Foxhound stands between 21 and 25 inches high, and weighs approximately 65 to 75 pounds, perfectly proportioned to its height. The American Foxhound has an amiable temperament, good with children and other dogs, and requires minimal grooming, but a lot of strenuous exercise.
BasenjiCalled the "barkless" dog, people often mistake the Basenji for an entirely silent breed. That is not the case, however. The Basenji does indeed talk, but without the harsh barking of a typical dog, and instead more of yodelling howl. A small dog of about 21 to 24 pounds, the Basenji has a body type similar to other primitive-type breeds: prick ears, lean and slender body, and neutral colors, like tan and white, black, and black with white. The Basenji also sports a curled tail, giving him a jaunty appearance. An old breed, the Basenji is thought to have come from central Africa.
Basset HoundThe Basset Hound has a unique shape with a heavy body, but very short legs. Its deep chest delivers a deep bark you'd expect from a dog three times its height, and its legs carry it farther and faster than you would think. Due its body shape, however, the basset Hound is prone to obesity and needs regular daily exercise to keep fit. The breed is known for its perpetual puppy dpg eyes and soft expression. Basset Hounds are good family pets, but can be stubborn and difficult to train.
Beagles come in two official hieght classes: 15 inches or 13 inches.
