These elegant dogs are legendary for their herding and protecting abilities. They are strong, loyal, affectionate, responsive and fast. The rough-coated Collie has a beautiful long coat. It can look as if it’s floating across the landscape when it runs. The coats of both varieties—rough and smooth—used to be mostly black, but now can be sable and white, tri-color, blue merle and white. The breed has an elegant wedge-shaped head. Collies can do well in the country or the city, but need companionship.
