Not a true miniature, this breed was developed in the 1930s – going against type in a period when breeding consistently larger Bull Terriers was the norm. It was initially defined by a lower weight, but is now defined by its height, which allows the dog to keep the same sturdy build characteristic as the Bull Terrier. The Miniature Bull Terrier shows more typical terrier temperament than the larger version, being aggressive towards other dogs and inclined to snap if teased. It settles into urban life well and will make an effective watchdog and humorous companion.
