The Bull Terrier took shape in mid-nineteenth-century England, when James Hinks refined bull-and-terrier crosses into a sleek, white companion. Colored Bull Terriers came later and are judged as a separate variety. The egg-shaped head with no stop and small, triangular eyes is unmistakable, and the short, harsh coat covers a compact, heavily muscled body of about 50 to 70 pounds.
Many Bull Terriers are affectionate, mischievous and stubborn in equal measure. They tend to crave company, play boisterously, chew hard and react poorly to unfamiliar dogs, which matters in busy Fort Worth parks. Steady, positive training and daily activity go a long way. Dogs vary, so spend time with the one you're considering.
