The Rhodesian Ridgeback is a dog breed developed in Southern Africa. Its European forebears can be traced to the early pioneers of the Cape Colony of southern Africa, who crossed their dogs with the semi-domesticated, ridged hunting dogs of the Khoikhoi. In the earlier parts of its history, the Rhodesian Ridgeback has also been known as Van Rooyen's Lion Dog, the African Lion Hound or African Lion Dog—Simba Inja in Ndebele, Shumba Imbwa in Shona—because of its ability to distract a lion while awaiting its master to make the kill. The original breed standard was drafted by F.R. Barnes, in Bulawayo, Southern Rhodesia (now Zimbabwe), in 1922. Based on that of the Dalmatian, the standard was approved by the South African Kennel Union in 1926.The Rhodesian Ridgeback's distinguishing feature is the ridge of hair along its back, running in the opposite direction to the rest of its coat. It consists of a fan-like area formed by two whorls of hair (called "crowns") and tapers from immediately behind the shoulders down to the level of the hips. The ridge is usually about 2 inches (5 cm) in width at its widest point. It is believed to originate from the dog used by the original African dog population, which had a similar ridge. The first depiction of a Ridgeback is a wall painting describing the life of the Boers, housed in South Africa in the Voortrekker Monument. Male Ridgebacks should stand 25–27 inches (63–69 cm) at the withers and weigh about 85 lb (39 kg) FCI Standard); females should be 24–26 inches (61–66 cm) tall and about 70 lb (32 kg) in weight. Ridgebacks are typically muscular and have a light wheaten to red wheaten coat, which should be short, dense, sleek and glossy in appearance, and neither woolly nor silky.
