Breed of working dog developed in Great Britain, probably by the 18th century.
The rough-coated variety was originally used to guard and herd sheep; the smooth-coated variety was used to drive livestock to market. Both varieties are lithe dogs with a tapering head, almond-shaped eyes, and erect ears that tip forward at the ends. They stand 2226 in. (5666 cm) tall, weigh 5075 lb (2334 kg), and may be variously coloured. See also border collie .
