The Border Collie comes in two coat varieties: rough or smooth. Both varieties are double coat and weather resistant and are close fitting and thick. The outer coat is either wavy or straight and coarse in texture. The under coat is dense, short, and soft. The rough coat variety has fur of medium length.
According to American Kennel Club standards, the border collie's height ranges between 18 and 22 inches at the shoulder, while the Labrador retriever's height ranges between 21.5 to 24.5 inches. The Lab's weight runs between 55 and 75 pounds, while the border collie ranges between 30 and 45 pounds. In both breeds, males are larger than females. Your borador should fall somewhere in the middle of the two parent breeds, almost as tall as but thinner than the Lab.
