English Cocker Spaniel

Dog

The English Cocker Spaniel is a breed of gun dog. The English Cocker Spaniel is an active, good-natured, sporting dog, standing well up at the withers and compactly built. There are "field" or "working" cockers and "show" cockers. It is one of several varieties of spaniel and somewhat resembles its American cousin, the American Cocker Spaniel, although it is closer to the working-dog form of the Field Spaniel and the Springer Spaniel.
