The Bull Terrier is a compact, heavily muscled dog of about 50 to 70 pounds, best known for its egg-shaped head with no stop and small, triangular eyes. James Hinks developed the breed in mid-nineteenth-century England as a sleek companion, and the white and colored varieties are judged separately. The short, harsh coat sheds moderately and needs little more than weekly brushing.
Personality is the main draw. Many Bull Terriers are comical, affectionate and devoted, with a mischievous streak and a stubborn one. They tend to chew hard, play roughly and dislike being left alone, and some react poorly to unfamiliar dogs. Steady, reward-based training and daily exercise go a long way, though each dog's history and personality still vary.
