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.
Working terrier A working terrier is a small type of dog which pursues its quarry into the earth. According to the "Oxford English Dictionary", the name dates back to at least 1440, derived from French "chien terrier" 'digging dog', from Medieval Latin "terrarius", ultimately from Latin "terra" (earth).
