Collie

**Semantic type:** Mammal

**Definition:** An active and agile, long-coated sheepdog. It has a lean, blunted, wedge-shaped head that is flat on top. The trim, but muscular, body is slightly longer than it is tall. In the Rough variety, an abundant double coat forms a mane around the neck and chest. The Smooth variety has a one-inch coat that needs very little grooming. Coats may be sable and white, tri-color (black, white and tan), blue merle, or predominantly white with sable, tri-color, or blue merle markings. The average height range is 22-26 inches and the average weight range is 56-75 pounds.
