Among the most comical and mischievous citizens of dogdom, the Bull Terrier is playful and endearing, sometimes stubborn, but always devoted. These unique 'eggheads' are exuberant, muscular companions who thrive on affection and exercise. Bull Terriers are robust, big-boned terriers who move with a jaunty stride suggesting agility and power. The breed's hallmark is a long, egg-shaped head with erect and pointed ears, and small, triangular eyes that glisten with good humor. Coats come in two types: white; and any other color (including an attractive brindle striping), either solid or with white markings. A well-made BT is the picture of muscular determination and balance. There are four keys to BT happiness: early socialization with dogs and people; firm but loving training; ample exercise; and lots of quality time with his adored humans. If these requirements are met, there is no more loyal, lovable, and entertaining companion. This is the ultimate 'personality breed.'
