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.
Known primarily as a sheep herding dog, the Border Collie is an outgoing, friendly and high-energy dog. These highly motivated dogs are trained to work in partnership with their master but their first love is their livestock.he Border Collie controls its herd by maintaining vigorous eye contact and clapping.. When a Border Collie is clapping, it stretches its front paws out and lowers its chest to the ground while maintaining a fixed stare at the sheep in what is similar to a predatory position.
