Miniature Bull Terrier History

The Miniature Bull Terrier originated in England and is a direct descendant of the larger Bull Terrier. Breeders crossed Bulldogs, Old English Terriers, and Spanish Pointers to create the Bull Terrier, which was then used to produce a miniaturized version.

These dogs were originally bred for various purposes, including guarding people or property. By 1939, the Kennel Club in the United Kingdom recognized the Miniature Bull Terrier, separating the breed from its larger predecessor. And the American Kennel Club approved the Miniature Bull Terrier as a Terrier group breed in May of 1991.

Miniature Bull Terrier Traits

General Appearance

Miniature Bull Terriers have square-shaped, muscular bodies and are very strong for their relatively small size.

Coat and Coloring

The Miniature Bull Terrier’s close, short-haired coat can be solid white or colored. Colors include brindle (black and brown stripes), black and tan, fawn, or red with varying amounts of white. Some dogs have pink skin around the muzzle and nose.

Distinctive Physical Traits

You can identify Mini Bull Terriers by their large, egg-shaped heads and dark, triangular eyes. Their ears point upward, and their tails taper to a fine point.

Miniature Bull Terrier Temperament

Bright and friendly, Miniature Bull Terriers are people-loving and courageous dogs. They are very loyal to their family, and usually good with children—though they need careful supervision when they’re around kids. Mini Bull Terriers can sometimes be unpredictable with dogs or other pets.

Miniature Bull Terriers have an even personality and often become very attached to their people—qualities that make them great for family life. They’re smart dogs that are eager to please, like to keep busy, and are always up for a challenge. But they have a silly side, too. The breed is known for being mischievous, playful, and even a little bit comical.

Miniature Bull Terrier Care


Miniature Bull Terriers require a high-quality dog food that is age-appropriate—whether it’s commercially produced or homemade (with approval and guidance from a veterinarian).

Some Miniature Bull Terriers are prone to obesity, so it’s important to monitor the amount of food you give them and keep track of their weight. If your pup gains weight, reduce their meal portions, or cut back on treats.


Grooming requirements for a Miniature Bull Terrier are pretty minimal. Regular baths and weekly brushing with a hound glove or soft brush are all that’s needed to keep this no-fuss breed looking its best.

A Mini Bull Terrier’s tough nails grow quickly. Since overgrown nails can cause pain or lead to issues walking, trim them regularly. And check their ears often for wax buildup and debris, which can lead to an infection.

Establish a routine of regular at-home teeth brushing in addition to professional dental cleanings.


Miniature Bull Terriers are a high-energy breed and need sufficient exercise to stay in decent shape (and maintain that good muscle tone they’re known for). But be careful with growing puppies—jumping up and down from high places or sudden stops at high speeds aren’t good for their developing joints.

Adult Mini Bull Terriers are typically very energetic and playful. They enjoy dog sports such as agility, flyball, rally, and competitive obedience.


To bring out the Miniature Bull Terrier’s best qualities, socialize them early and often.

When training a Mini Bull Terrier, use a firm hand and a gentle voice. This breed is inclined to guard, so dedicated training is needed to temper this tendency and maintain a safe household.

Miniature Bull Terriers respond well to reward-based training. Use this approach to reduce any stubbornness or to teach them to drop retrieved items.
