About the Miniature Bull Terrier Dog Breed

The Miniature Bull Terrier is a strong, sturdy, active dog, similar in every way to its larger cousin: the standard Bull Terrier. It has a determined expression and is full of spirit, though amenable to discipline. 

Miniature Bull Terrier Physical Characteristics

Moving with an easy and free gait, the Miniature Bull Terrier is a big-boned, square-proportioned and strongly-built dog. It shares many physical characteristics with its standard cousin, such as its strong jaws, muscles and bones.

To go with its comical behavior, the “Mini” has a clownish face and a determined, keen expression.


The breed can be solid white or colored.


The Miniature Bull Terrier has a harsh, short, and flat coat, with tightly-fitted skin.

Miniature Bull Terrier Personality and Temperament

Activity Level

Low to moderate


Just like the Bull Terrier, the Miniature is mischievous, playful, comical, and lively. It is also sweetly devoted but not flattering.

Things to Consider

The breed’s small size does not make it a lap dog – it is curious, independent, stubborn and in need of a firm yet gentle master.

Ideal Living Conditions

The Miniature Bull Terrier is not meant for outdoor living, but it does prefer access to the yard or garden. City-dwellers love this dog, as it can live in well-sized apartment or condominium.

Special Requirements

The Mini’s exercise regimen, consisting of a playful romp or a moderate walk, should be fulfilled every day, but not overdone. Coat care for the dog, meanwhile, is minimal, requiring little more than the occasional brushing.

Miniature Bull Terrier Health

The Miniature Bull Terrier, which has an average lifespan of 11 to 14 years, may occasionally suffer minor health concerns such as glaucoma and lens luxation, and major issues like deafness. The breed is also susceptible to kidney disease. To identify some of these issues, a veterinarian may recommend regular hearing and eye exams for the dog.

Miniature Bull Terrier History and Background

Descending directly from the Bull Terrier, the Miniature Bull Terrier shares much of the former’s background. Initially, the earliest specimens of the Bull Terrier came in a wide range of sizes, a direct result of the variations of sizes of the Bull’s ancestors: the White English Terrier, Bulldog, and Black and Tan Terrier.

The smallest of the white Bull Terriers were known as Coverwood Terriers, named after the kennel in which they were produced. There are also records that show small Bull Terriers of other colors existing, these weighing in at about four pounds. And though the tiny toy dogs were of a poorer variety – quickly losing the interest of the population – slightly larger dogs (or miniatures) were considered of better stock.

The English Kennel Club recognized the Miniature Bull Terrier by 1939, but recognizing it as a distinct breed posed a problem. The Miniature could not be crossed with the standard Bull Terriers, as it was a separate breed. However, with just a few Miniatures present, there were several instances of interbreeding.

The Miniature Bull Terrier breed became popular gradually, and the American Kennel Club eventually recognized it in 1991. Even though it remains an uncommon breed, this miniature form of the Bull Terrier is sure to see a rise of popularity.
