The Rhodesian Ridgeback is a unique creation of southern Africa, resulting from crosses between the native ridged Khoikhoi dog and European breeds brought by Dutch colonists, including Greyhounds and various Terriers. The infusion of native Khoi blood gave resulting generations a resiliency against local pests such as the tsetse fly, as well as an inborn knowledge of how to navigate their new African environments and outwit its deadly predators. In the late 19 Century, Rhodesian big-game hunter Cornelius van Rooyen incorporated two ridged Greyhound-like females into his pack of lion dogs. He found that their ridged offspring excelled at confronting and confounding the king of beasts, giving the hunter time to sight in his rifle and dispatch his prey. These ridged dogs were also successful at fending off other dangerous animals such as leopards and baboons, trotting effortlessly alongside horse-mounted riders all day, breaking off to course quick-footed game such as antelope to provide meat for the pot, and protecting the homestead from all intruders. They were known then, as they are today, for their devotion to family, and tolerance and affection for its children.
