The American Cocker is the smallest dog in the AKC Sporting Group. Its spaniel ancestors flushed woodcock for English hunters, and the American version became a smaller dog with a domed head, large dark eyes, a short square muzzle and a long, silky coat in black, solid colors or parti-colors. In the US, "Cocker Spaniel" means this American type, not the taller English Cocker.
Most Cockers are cheerful, gentle and eager to be near their people, and they respond best to soft, patient training. They adapt well to different homes but not to skipped upkeep: the coat needs regular brushing and a trim every six to eight weeks, the long ears need weekly checks, and eye and ear problems are common in the breed. Dogs vary, so a Cocker's own personality matters more than the breed description.
