To separate this breed from the Border Collie and the Smooth Collie, they are referred to as Rough Collies or Long-Haired Collies. They can stand up to two feet at the shoulder and weigh up to 75 pounds.
They are double-coated, with an outer coat of long, dense fur and a downy undercoat. The fur on the face is short, and they have a long, wedge-shaped snout.
There are many recognized coat colorations, but the most common is “sable” with white on the chest, underside and neck, and brown on the back and face. The brown may range from a light tan to a dark mahogany.
