Miniature bull terrier is a small, muscular dog. Except for its smaller size, it is identical to the bull terrier. Breeders in England developed the miniature bull terrier by mating small bull terriers to one another.
The miniature bull terrier stands about 10 to 14 inches (25 to 36 centimeters) high and usually weighs 15 to 30 pounds (7 to 14 kilograms). It has a long, wide head; small eyes; pointed ears; a short, glossy coat; and a short, straight tail. Miniature bull terriers most commonly are white. They also may be gray, brown, tan, red, or other colors, usually with white markings.
Miniature bull terriers are regarded as intelligent, alert, and friendly. They make good show dogs and pets.
