About the Miniature Bull Terrier

The Miniature Bull Terrier is the same dog as its larger relative in every respect except height, which the standard caps at 35.5 cm, and it has been registered as a breed in its own right since 1939. The two are not interbred, so a Miniature litter comes from Miniature parents on both sides.

Everything about the type should read as a scaled version of the larger dog: the egg-shaped, down-faced head with no stop, the small triangular eye, the erect ear and the muscular, well-filled body. Colour may be white or coloured, brindle preferred among the coloureds. A stud should be balanced and free-moving rather than merely small, and an undersized dog with a poor head is not the same thing as a good miniature.

Primary lens luxation is the single most important test in this breed, it has a reliable DNA test, and no responsible owner will be surprised to be asked. Kidney disease matters here as well, so ask for a urine protein-to-creatinine ratio result and for a cardiac examination. Hearing should be checked by BAER, particularly in white dogs. A patella assessment and an annual eye examination round the list off.

Health & breeding

We check every hip, elbow, eye and DNA result you give us against the Royal Kennel Club’s public records by hand, and we record who checked it and when. The Royal Kennel Club’s public records may not include all the screening a dog has had, so a dog with no Royal Kennel Club record showing is not necessarily untested.

Health tests for the Miniature Bull Terrier

This panel is Breed Right’s summary of the testing that matters for the breed under The Royal Kennel Club Health Standard. The Health Standard is the Royal Kennel Club’s guidance for breeders, not a registration rule. It describes tests to ask about — it is not a report on any individual dog. The Royal Kennel Club’s public records may not include all the screening a dog has had, so a dog with no Royal Kennel Club record showing is not necessarily untested.

Best Practice — further tests it recommends

Completing these as well as the Good Practice tests is what the Royal Kennel Club calls Best Practice.
