The Bearded Collie is extremely smart, cheerful, playful, and always active. Full of enthusiasm and energy, the dog is obedient in nature and prefers to spend time with people. It can have an independent attitude at times, but loves playing with children; and although it can become too boisterous with children, it is never intentionally aggressive. Otherwise, the Bearded Collie is pleasant to live with. The Bearded Collie has a sturdy medium-sized body. Its long, lean body provides it both power and agility, essential qualities in a sheep herding dog. Besides its ability to make smooth, quick movements, the Bearded Collie possesses a double coat, which is soft and furry underneath with a straight, flat, and coarse outer coat. This outer coat comes in either black, blue, brown, or fawn, with or without white markings. Its facial expression is both bright and keen.
