This beautiful Spaniel has very long hanging ears, a rounded, refined and cleanly chiseled head with an abrupt stop, and a profuse, silky, feathered, medium-length coat. The muzzle is wide, deep and broad with a square jaw. The nose is always black on black dogs, but may be brown on other dogs.
The American Cocker Spaniel has a compact, body with a short back. The front legs are straight, with good bone. Dewclaws on front and rear legs should be removed. Their coat is much thicker than the English Cocker Spaniel has, it comes in buff, black, and other solid colors, black-and-tan (like a Rottweiler or Doberman Pinscher), parti-color (white with black, white with buff or red, white with black and tan points).
Some requirements for correct markings are specified in the relevant standard. Field lines generally have shorter coats which are better suited to work in brush. They also have better hunting instincts. Both types make good pets. This breed is known as the Merry Cocker, their charming personality makes them the world's most popular household pet. The American Cocker Spaniel is an excellent bird and small-game hunter, great companion, good with children and all around friendly, lively guy.
Black, jet black, shading of brown or liver in sheen of coat undesirable; black and tan and brown and tan, with definite tan markings on jet black or brown body; particolors and tricolors.
Short and fine on head, medium length on body, with enough undercoat to give protection.
