First bred in 19th-century England, the Bull Terrier is the clown of dogs. Robust and spirited, this playful, fun-loving breed is always ready for a frolic. He loves children, but obedience training is necessary and care must be taken that he does not get overstimulated around younger children. Friendly and affectionate, Bull Terriers thrive on human companionship. This active, well-muscled breed needs daily exercise and has a low-maintenance coat.
