Norwich terrier is a breed of dog that developed in England about 1880. Norwich terriers are alert, quick, sturdy, and instinctively good at hunting mice, rats, and other small animal pests. They make good pets as long as they get plenty of exercise and attention.
Norwich terriers are very similar to Norfolk terriers. But the ears of Norwich terriers stand erect, and those of Norfolk terriers drop forward. The Kennel Club in England recognized the dogs as separate breeds in 1964. The American Kennel Club recognized them as different breeds in 1979.
Norwich terriers may be any shade of red, or black and tan. They have a straight, wiry outer coat and a harsh undercoat. The dogs have short, sturdy legs, and sometimes their tail is docked (cut) to 3 to 4 inches (8 to 10 centimeters) in length. Full-grown Norwich terriers stand about 10 inches (25 centimeters) high at the shoulder and weigh from 10 to 12 pounds (4.5 to 5.4 kilograms).
