Are the English Cocker Spaniel and Jack Russell Terrier large dog breeds?
English Cocker Spaniel 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 English Springer Spaniel.
American Staffordshire Terrier The American Staffordshire Terrier, also known as "Amstaff" (in the United States) or simply "Stafford", is a medium-sized, short-coated American dog breed. It is one of several breeds commonly known as pit bulls. In the early part of the twentieth century the breed gained social stature and was accepted by the American Kennel Club in 1936. The name was changed to reflect difference from the Staffordshire Bull Terrier of England.
