The Shetland Sheepdog is related to the Rough Collie, both dogs descended from Border Collies that inhabited Scotland. The Border Collies were brought to the Scottish island of Shetland and crossed with the Icelandic Yakkin, a small island dog which is now extinct. By 1700, the Sheltie was completely developed.
Rhodesian Ridgebacks are a combination of seven distinct breeds including the Khoi dog of Africa, the Greyhound, the Bulldog, the Collie, the Pointer, and the Airedale and Irish Terriers. The result is a dog that is tough enough to face a lion or other big game, but fast enough to avoid the horns, claws or teeth of such an adversary.
