Those big, dark eyes; that sweet expression; those long, lush ears that practically demand to be touched—no wonder the Cocker spent years as America’s most popular breed. The Cocker is the AKC’s smallest sporting spaniel, standing about 14 to 15 inches. The coat comes in enough colors and patterns to please any taste. Cockers are eager playmates for kids and are easily trained as companions and athletes. They are big enough to be sporty, but compact enough to be portable.
