The Miniature Bull Terrier typically weighs 8-15 kg, stands 25-35 cm, and lives 11-14 years.

Consider this breed if…

you want a playful, clownish terrier with a big personality in a small dog,
you can give it firm, fun, consistent training and daily exercise,
you have experience with strong-willed, terrier-type dogs,
you will buy from a breeder who tests for lens luxation, deafness and kidneys.

Do not consider this breed if…

this is your first dog and you want an easy, biddable one,
you have small pets or dog-reactive dogs it must live beside,
you cannot commit to daily exercise and mental work,
you want a calm couch companion rather than a busy terrier.

Frequently asked questions

How much does a Miniature Bull Terrier cost?
Puppies from health-testing breeders in the US commonly run about $1,500-$3,500, and this is an uncommon breed, so expect waitlists. The purchase price is the small part: across an 11-14 year life, food, training and routine vet care typically add $12,000-$18,000 or more, and treating a problem like lens luxation or kidney disease can add thousands on top.
Are Miniature Bull Terriers good with other dogs?
Not reliably. Many are pushy or scrappy with other dogs, and same-sex aggression is a known issue in the bull terrier family. Early socialization helps, but expect to manage introductions and never assume off-leash dog parks are safe.
Are they easy to train?
They are clever but stubborn and easily bored. Short, upbeat, reward-based sessions work; repetition and harsh corrections do not. Think of training as an ongoing game rather than a course you finish, and start early.
What health tests should the breeder have done?
Ask specifically about the DNA test for primary lens luxation, BAER hearing testing, kidney screening (UPC ratio) and a cardiac and patella check. A responsible breeder will share these results without being pushed.
