Go on, try to resist that face. We double dog dare you. Those big, dreamy eyes, that sweetie-pie expression, those long, lush ears that practically demand to be touched—no wonder the Cocker has been America’s most popular breed many times during its long history. The Cocker is the AKC’s smallest sporting spaniel, standing about 14 to 15 inches at the shoulder. The coat comes in enough colors and patterns to please any taste. The body is strong and solid, with smooth, easy movement.
