The Rhodesian Ridgeback is a large dog breed bred in the Southern Africa region. Its forebears can be traced to the semi-domesticated ridged hunting and guardian dogs of the Khoikhoi. These were interbred with European dogs by the early colonists of the Cape Colony of southern Africa. The original breed standard was drafted by F. R. Barnes, in Bulawayo, Southern Rhodesia (now Zimbabwe), in 1922, and approved by the South African Kennel Union in 1927. The Rhodesian Ridgeback at present is the only registered breed indigenous to Southern Africa.
