The Rhodesian Ridgeback is a dog breed indigenous to 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 Khoisan people (referred to by the colonists as "Hottentots").

The 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.
Male Ridgebacks should be 63-69 cm at the withers and weigh approximately 36.5 kg (FCI Standard), females 61-66 cm and approximately 32 kg. 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.
Ridgebacks have a strong, smooth tail, which is usually carried in a gentle curve backwards. The eyes should be round and should reflect the dog's color—skin pigment, not coat color: dark eyes with a black nose (regardless of coat color), amber eyes with a liver nose. The liver nose is a recessive gene. It is not as common as a black nose.
Ridgebacks are loyal and intelligent. They are, however, aloof to strangers. This is not to be confused with aggression: A Ridgeback of proper temperament will be more inclined to ignore a stranger than to challenge them. This breed requires positive, reward-based training, good socialization and consistency, and is often not the best choice for inexperienced dog owners. Ridgebacks are strong-willed, intelligent, and many seem to have a penchant for mischief, though lovingly. They may not make a good first dog, though the same traits that make them difficult often appeal to the more experienced owners. They can withstand wide temperature variations due to their African heritage.
Health conditions known to affect this breed are hip dysplasia and dermoid sinus which is the canine version of the human condition, spina bifida.
