NCI: The Collie is 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. They both come in sable and white, tri-color (black, white and tan), blue merle or predominantly white with sable, tri-color or blue merle markings. Height: 22-26 inches (56-66 cm.) Weight: 56-75 pounds (27-34 kg.) (dogbreedinfo.com)
