Smooth Collie
The Smooth Collie is a medium to large dog, ranging in size from 20-26 inches at the shoulder and weighing 40-75 pounds. Standard size for the breed is on the larger end of the range in the United States and Canada, smaller elsewhere; for example, for the AKC, the range is 22 to 26 inches (56-66 cm) and 50 to 75 pounds (22.5-34 kg). In all standards, females should be significantly smaller than males. The Smooth Collie is slightly longer than it is tall, with a level back and a deep chest. The features of the head, particularly the "sweet" expression, are considered very important in the show ring. The breed has a long muzzle, flat skull, and semi-erect ears.
