The Smooth Collie is a breed of dog developed originally for herding. It is a short-coated version of the Rough Collie of Lassie fame. Some breed organisations consider the smooth-coat and rough-coat dogs to be variations of the same breed.
Originally developed in Scotland for herding livestock in rugged terrain.
The Smooth Collie is a herding dog known for its intelligence and agility. It is closely related to the Rough Collie and is distinguished by its short coat. Smooth Collies are excellent family pets due to their gentle nature and loyalty. They excel in dog sports and enjoy active lifestyles.
