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, which is also shared to some degree with the Khowaty Bull Terrier of Pakistan, which is believed to have been developed using Bull Terrier 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 this breed may also be more prone to deafness and some types of cancer and allergies.
This breed 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 1800's before the classic egg shape head was developed the breed divided between its ancestors the Bull Terrier and Staffordshire Bull Terrier.
Later in its history additional breeds of the Dalmatian, Greyhound, Spanish Pointer, Foxhound and Whippet were reportedly used to increase elegance and agility; and Borzoi and Collie to reduce the stop. The first modern Bull Terrier is now recognized as "Lord Gladiator", from 1917, being the first dog with no stop at all.
