The Rhodesian Ridgeback is a large, handsome, muscular dog. Its name describes its most unique characteristic, a clearly defined symmetrical ridge running the length of its back, formed by hair that grows in the opposite direction from the rest of its coat. This impressive, protective hound was used to hunt game, retrieve, take care of children, and guard property. South African hunters discovered that this breed, used in packs, was very effective against lions, hence the breed's other name, the African Lion Hound. This unique dog is well adapted to the harsh African environment; it can withstand very high temperatures and the damp cold of night. This breed is insensitive to insect bites and can go without food and water for over 24 hours.
