The Rough Collie (also known as the Long-Haired Collie) is a long-coated dog breed of medium to large size that, in its original form, was a type of collie used and bred for herding sheep in Scotland. More recent breeding has focused on the Collie as a show dog, and also companion. The breed specifications call for a distinctive long narrow tapered snout and tipped (semiprick) ears, so some dogs have their ears taped when young. Rough Collies generally come in shades of sable and white (sometimes mahogany), blue merle, tri-colored, and white.
