The Miniature Bull Terrier is a strongly built, square-proportioned dog, big-boned but not coarse. It should reflect those attributes that made the standard-sized bull terrier a formidable foe in the fighting ring with its sturdy bone and muscle and strong jaws. Its gait is free and easy. Its skin is tight and its coat is short, flat and harsh. It wears a keen and determined expression on its characteristic clown face.

Very much like the larger bull terrier, the mini is comical, lively, playful and mischievous. Despite its smaller size, it is not a lap dog. It is every bit as tough as the larger version and apt to want to prove itself even more. It is a sweet clown, devoted but not fawning. It is stubborn and independent and needs to be trained with a firm yet gentle hand — and a good sense of humor. It likes to play and investigate. It likes to dig, and it needs ample exercise.
