Lycaon pictus is a large canid found only in Africa, especially in savannas and other lightly wooded areas. It is variously called the African wild dog, African hunting dog, Cape hunting dog, painted dog, painted wolf, painted hunting dog, spotted dog, or ornate wolf.
The scientific name "Lycaon pictus" is derived from the Greek for "wolf" and the Latin for "painted". It is the only canid species to lack dewclaws on the forelimbs.
Adults typically weigh 18–34 kilograms (40–75 lb). A tall, lean animal, it stands about 75 centimetres (30 in) at the shoulder, with a head and body length averaging about 100 centimetres (39 in) long with a tail of 30 to 45 centimetres (12 to 18 in). Animals in southern Africa are generally larger than those in eastern or western Africa.
