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.
