Boston Terrier or Boston Bull is a breed of nonsporting dog, originated by crossing an English bulldog with a white English terrier. The Boston terriers, recognized by the American Kennel Club as a distinct breed in 1893, are descended from a dog owned about 1884 by a native of Boston. The Boston terrier is a small dog, weighing about 7 to 11 kg (about 15 to 25 lb). It has a square, flat skull; large, round, dark eyes that are alert and intelligent; a smooth coat, usually brindle in color with white markings, or black with white markings; a short, square muzzle; small, thin ears; a wide chest; and a short, tapering tail. The Boston terrier is lively, strong, intelligent and gentle—an ideal pet.
