Breed Overview

Origin: 1800’s. Original function: Companion. Today, Companion.

Around 1835, a cross between the Bulldog and the old English Terrier produced a particularly adept dog known as the Bull and Terrier which was suppose to be the great “fighting dog.”. Around 1860, crosses of the Bull and Terrier with the White English Terrier were made in an attempt at getting an all-white specimen. They produced an all-white strain they called Bull Terriers. A new all-white strain immediately succeeded and caught the attention of the public. The was a very strong fighting dog that provided plenty of entertainment. Around the same time, a smaller version of the same dog was bred to be a companion pet and household protector. The smaller version, the Miniature Bull Terrier was recognized by the AKC in 1991 and has seen modest popularity in the States.

Not easy to train. She is a bit sensitive so positive training is a must. Use clicker training, positive reinforcement with lots of praise. Make training lots of fun for her. Have patience. She can learn in time.

Crate Training

Want to crate train your Miniature Bull Terrier? It's easy and if you're interested, take a look and you'll see what to do. Crate training your Mini Bull Terrier puppy will save many headaches and problems.

Potty Training

Most Miniature Bull Terriers are fairly easy to house train, potty train, toilet train, housebreak or whatever you want to call it. If you have a puppy, decide if you want to crate or paper potty train it. For the best results, we have a page at Crate vs Paper Potty Training which will help you decide and from there you can get all the information you need to get the job done. Always praise the pup profusely when she goes potty in the RIGHT PLACE so she knows she has done a good thing. Either method will work for this breed.

If you have an older dog, take the dog outside every two hours until she gets the idea which door leads to her potty area. Older dogs catch on to the potty or housebreaking pretty fast once they are shown what to do.


The Miniature Bull Terrier is quite similar to the full size Bull Terrier. Active, lively, comical and tough for it’s size. While this is a friendly, sometimes silly dog, it is not one for the first time dog owner. She can be independent and stubborn, especially when it comes to training and mingling with strange dogs and people. The breed needs firm, strong training and socialization from early puppyhood onward. She is a bit sensitive so positive training is a must. A basic terrier, she likes to dig, run, play and investigate new places and smells. This breed must never be allowed to dominate the household, as they will tend to try to do.

If you happen to get a Mini Bull with a separation anxiety problem, that can be dealt with by investing a few hours of work on your part and some "tough love."

Friendly Toward Other Dogs

No, not thrilled with dogs. Picks and chooses her dog friends. Can be a little aggressive and lack trust with other dogs.

Friendly Toward Other Pets

May get along with some pets. Best if raised with them. Introduce other dogs on common ground and introduce cats slowly. Small animals like hamsters not a good idea.

Friendly Toward Strangers

Wary of people. Can warm up quickly once she know there is no threat but there is always some lack of trust.


Yes, Very playful little dog. Loves games where she can run and romp around.


Not as affectionate as one might think. She is devoted to family but is slow to roll over for tummy rubs and a bit short on kisses.

Good with children?

Older, well mannered children, okay, although this dog is not as affectionate as some kids would like.

Good with Seniors over 65?

No, not my first choice. Needs too much exercise, is not affectionate enough and too wary of other people to be a close companion.

Living environment

Sunburn sensitive. Must be kept out of the sun. Do not leave this dog outdoors for extended periods. The Bull Terrier has sensitive skin.

Apartment, house with small fenced yard and doggie door is ideal, farm, ranch all okay. She needs to be indoors with her family. The Miniature Bull Terrier is a social breed.


Energy level

Quite Energetic. I’d give her 8 bars out of 10 for energy.

Exercise Needs, Daily

Moderate. One or two good walks a day, some fetch or other vigorous play time in the yard or park and maybe some training sessions will take care of it. She might enjoy jogging on leash.


Excellent watchdog. She’ll give warning of anything unusual, at home, in the car or wherever.

Guard dog

Fairly good guardian. Good at guarding the family and house.


Very little.


Brush once a week. Your dog will thank you for the extra attention.

Dog Health Issues For The Miniature Bull Terrier
Below are the dog illness / illnesses or medical problems listed for the Cairn by various vets.

This is basically a healthy breed. Don’t let the list below scare you! Your own dog will probably never have ANY of these problems. These are dog illness and medical issues this breed is prone to that have been listed by various veterinarians at different times over the past decade or so and some pertain to puppies and very young dogs that a breeder would deal with.

The information contained herein has been gathered from numerous books by veterinarians and is intended as general information only. Every dog and situation is different. You must see your vet. Our information is for general interest only and not intended to replace the advice provided by your own veterinarian.

  • Sunburn - This breed is highly sensitive to the sun. Sunburn is a problem due to sensitive skin when it is exposed to the sun's rays for a prolonged amount of time. Keep the dog INDOORS except for short walks and a little play time.

  • Deafness—(mainly in the all white dogs) Hereditary or caused by: Excessive loud noise, Intolerance to anesthesia, drug toxicity, and Otitis (middle ear infection), In some cases, one ear can have no hearing from birth and the other ear can be losing the ability to hear over time, undetected, then suddenly one morning the hearing is totally gone. There is no reversing once that happens.

  • Mast Cell Tumors—Mast cells are found throughout the body and help maintain the dog’s normal immune response, health and body functions. The tumors in question are CANCEROUS and spread through the body. There is no known cause for mast cell cancer and no cure, other than surgery for early-detected, low degree tumors that haven't spread too far. The best formula is to keep the Miniature Bull Terrier as healthy as possible and be aware of any signs of tumors or poor health. Whether the dog survives or not depends on how advanced and fast moving the malignant tumor is.

  • Glaucoma—Painful pressure builds in the eyes causing blindness.

  • Entropion—Eye irritation caused by the eyelids and lashes rolling inward. The problem is usually inherited and found in young, adult dogs. It can come from an eyelid spasm. Affected eyes will be held partially shut and tear excessively. Both eyes will usually be affected the same. Treatment for the condition requires eye surgery.

  • Lens luxation—Hereditary. Weak fibers holding the lens of the eye allow the lens to dislocate. The eye can not focus. This leads to painful, red eyes that tear a lot and can lead to Uveitis or Glaucoma if not treated right away. If detected early, surgery and medication might solve the problem.

  • Tail spinning - the Miniature Bull Terrier, with no warning, starts spinning around, or chases her tail and won't seem to quit. It's an abnormal behavior problem with no known cause.

  • Polycystic kidney disease—Chronic renal (kidney) failure. Caused by a number of thins such as parasites like kidney worms, infections, and toxins like vehicle anti-freeze. Symptoms are depression, vomiting, loss of appetite and less (or more) urinating than usual. Because the symptoms are so common, many Miniature Bull Terrier owners tend to overlook the problem and let the illness go too long before seeing the vet when it’s too late to save the dog. Depending on the cause, it may be treatable with medication, liquid therapy, diet, and possibly dialysis. In very rare cases, some vet clinics have done kidney transplants.

    Miniature Bull Terriers and Bull Terriers are known for kidney problems so have yours check regularly.

Other health problems could occur with your Miniature Bull Terrier. If you notice any problems with your dog, take it to the vet immediately. This website is for general information only and is not intended to, in any way, be a medical guide.
