The Miniature Bull Terrier is a breed which originated from a cross among the English White Terrier, the Bulldog, and the Dalmatian. This cross was first documented sometime in 1872. Since then, the Miniature breed has gone a long way into being accepted in the AKC since 1991.

Looking back, it was quite popular for Bulldogs and Terriers to be crossed in the 1800’s. It created the new Bull Terriers which were combated versus Bulldogs for sport. These initial crosses were further refined to include the Spanish Pointer whose blood resulted in the bigger Standard Bull Terrier.

When England first created in the Standard breed of Bull Terriers in the 19th century, they were almost the same size as the Miniatures now. It was a cross breeding with Pointers which increased them to their standard fighting form. Soon, the white-coated variety became popular among nobles as a fashion pet. Meanwhile, crossing with The Staffordshire produce the colored variety.

More manageable in size than the Standard variety, the Miniature Bull Terrier still retains its most basic qualities. Depending on how you see it, the Standard and the Miniature can be treated as two separate breeds (AKC) or two different varieties of one and the same breed (UKC).

Miniature Bull Terriers are so little and fine-featured, they look more like Chihuahuas than Terriers. Small yet symmetrical in built, they are strong, muscular, and active.

Full of fire, the Miniature variety is possessed with a lot of will and determination. When confronted with a bigger dog, it tends to forget that it is a much smaller dog. They will be ready to pick up a fight, revealing their past, inherent nature as a gladiator and combatant.

With ears erect, they are smart and intelligent creatures full of play and energy. They can be stubborn and willful to a fault, but these can be corrected by proper training and firm leadership. All in all, they can be tamed into gentleness.


The average lifespan of the Miniature Bull Terrier is 10 to 14 years.

While the Miniature Bull Terrier is generally a healthy dog, it is susceptable to certain health problems. These problems include:

  • Hereditary Nephritis - A severe kidney disease associated with Bull Terriers. This disease is often found at an early age and is caused by small, under-developed kidneys or by a malfunction of the kidney'#8217;s filters, resulting in high levels of protein in the urine. Bull Terriers with this disease usually die within three years, but some dogs live to be 6 to 8 years old before succumbing to kidney failure. This can be diagnosed using a urine protein/urine creatinine (UP:UC) test, which shold be performed annually. If your dog is diagnosed with a high protein level in her urine, do not breed her, since this is a hereditary disease.
  • Polycystic Kidney Disease (PKD) - A disorder in which large portions of the functional tissue of the kidneys are displaced by multiple cysts. Although polycystic kidney disease is usually not immediately life-threatening, it should be treated as early as possible to prevent cyst progression and development of secondary bacterial infection.
  • Lens Luxation - The dislocation of the lens of the eye from its normal location. Depending on where the lens dislocates to, this could result in glaucoma.
  • Patellar Luxation - Sometimes called a trick knee, this condition causes the kneecap to pop out of place. This can be caused by obesity, but is typically a congenital defect that can be inherited.
  • Aortic Valve Stenosis - A form of heart disease where the aortic valve opening is narrowed. The aortic valve supplies blood from the left ventricle to the aorta, which carries the entire output of blood to the systemic circulation.


Devoted and affectionate, well-trained Miniature Bull Terriers make great family companions. They feed on little and are easy to maintain, but they hate being left alone for long. They thrive much on structure and supervision at home.

To nurture them as pets, keep them occupied and far from being idle. A sufficient amount of physical and mental exercise combined with play outdoors should do the trick! Otherwise, you’ll be faced with destructive behavior and obsessive licking.
