The Bull Terrier is a breed of dog in the terrier family. There is also a miniature version of this breed, the Miniature Bull Terrier. This breed originates in England, where the bull and terrier breeds were originally bred for vermin control and bloodsports. In the mid-19th century, James Hinks began breeding the bull and terriers with English White Terriers, eventually resulting in the modern breed. The Bull Terrier has a distinctive 'egg-shaped' head, triangular eyes, and a robust body.
Bull Terriers have a slightly below average lifespan. White bull terriers have a strong tendency towards deafness, and may also inherit lethal acrodermatitis.
