If the Standard Bull Terrier appears to be a ferocious gladiator dog and a gentle companion, the Miniature Bull Terrier is exactly the same only smaller. The Standard Bull Terrier was originally used as a fighter dog in the notorious bull baiting past time of 1800s England but when this act was prohibited, breeders started to take care of this breed for companionship purposes only. Soon after, the Miniature Bull Terrier was born in the purpose of owning the same Bull Terrier appearance and characteristics but only in a more portable size.

Once known as a gladiator in the bull baiting pit, the Standard Bull Terrier has come a long way and is now being enjoyed as a family pet. After the bull baiting was banned, breeders found a way to somehow lessen the aggressiveness of this breed and this quest was successful. Down the line, however, breeders came up with the idea of having the same Bull Terrier only smaller in size thus the Miniature Bull Terrier came to be.
