The classic Bull Terrier is probably best recognized from its Bud Light and Target ads. The Bull Terrier is notable for its classic wedge/egg head shape, also shared to some degree with the Khowaty Bull Terrier of Pakistan, believed to have been developed using Bull Terrier as part of its foundation stock.
This breed comes in both a standard and miniature variety. This breed is known for its stubborn personality and thus is not typically encouraged for new dog owners.
Due to the primary white coloration of many specimens, the Bull Terrier may also be more prone to deafness and some types of cancer and allergies.
The Bull Terrier was developed based on the Old English Bulldog and White Terrier, which are now extinct, as well as the Old English and Black and Tan Terrier. In the early 1800s, before the classic egg shape head was developed, the breed was divided between its ancestors, the Bull Terrier and Staffordshire Bull Terrier.
Later in its history, additional breeds of Dalmatian, Greyhound, Spanish Pointer, Foxhound, and Whippet were reported to have been used to increase elegance and agility; and Borzoi and Collie to reduce what is known as the "stop", the area where the muzzle meets the forehead. The first modern Bull Terrier is now recognized as "Lord Gladiator", from 1917, being the first dog with no “stop” at all.
