The Bull Terrier is tough, spirited, and full of energy. But terrier breeds face their own health challenges - knee problems, skin allergies, and dental disease can add up fast.
Measured risks
How often they happen is backed by published studies.

Breed study [1] 65% (66/101) had heart disease on echocardiogram - mitral valve abnormalities 47%, aortic stenosis 29% (Chompoosan et al. 2022, JSAP). This is a referral/echo-screened cohort (likely dogs already suspected of cardiac issues) - flag selection bias; do not present as general-population risk. An older necropsy study found ~93% with valve/outflow abnormalities.
Bull Terrier has one of the highest documented rates of cardiac valve disease of any breed studied. Full profile →

All dogs General canine obesity prevalence; no Bull Terrier-specific breed effect confirmed.
Up to 40% of adult dogs are overweight. Obesity accelerates joint deterioration, increases cardiac load, and shortens life expectancy by 1-2 years. Full profile →

All dogs All-dogs baseline diagnosed dental disease rate; no Bull Terrier-specific breed effect confirmed.
Periodontal disease requiring professional cleaning or extractions. Full profile →

Breed study 10.19% overall prevalence (8.21% unilateral, 1.98% bilateral), n=1,060 BAER-tested dogs; white-coated dogs 19.29% affected, 96.29% of all deaf puppies were white-coated (Veterinary Journal study, PMC4957289).
Bull Terrier has an elevated deafness rate, especially in white-coated dogs, linked to pigmentation genetics. Full profile →
Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
Breed study ADAMTS17 mutation confirmed causative in Bull Terrier (Gould et al. 2011, Vet Ophthalmology). Heterozygous carriers have an estimated 5-10% lifetime risk; homozygous dogs are high-risk. No population carrier-frequency percentage specific to standard Bull Terrier was found (more detailed data exists for Miniature Bull Terrier).
A hereditary eye disease (ADAMTS17 gene, shared with Basset Hound's glaucoma mutation family) causing the lens to detach. Full profile →

Not measured No Bull Terrier-specific allergy study found; baseline rates should apply.
Chronic skin inflammation causing persistent itching and repeated infections. Full profile →

Breed study [4] Autosomal dominant hereditary nephritis, average onset age ~3.5 years (Hood et al. 1990, Vet Record). Real and genetically confirmed as a breed-defining condition, but no population prevalence percentage was found in the literature.
An inherited kidney disease, a canine model for human Alport syndrome, with onset typically in young to middle-aged dogs. Full profile →

Breed study [3] Abnormal EEG found in 7/7 affected Bull Terriers vs 0 controls; phenobarbital effective in 5/7 (Dodman et al. 1996, JAVMA). Heritable risk factors confirmed via pedigree analysis (Moon-Fanelli et al. 2011, JAVMA). No population prevalence percentage exists for how many Bull Terriers develop this.
Real, peer-reviewed research links this breed's characteristic compulsive tail-chasing to abnormal brain activity, not simple boredom. Full profile →

Not measured No confirmed Bull Terrier-specific epilepsy prevalence found.

How we know these numbers
- Confirmed = measured or gene-confirmed specifically in this breed
- Breed study = scientists counted it in this exact breed
- Body type = comes from the dog's build - size, skull, skin
- Genetic risk = the gene is proven, the odds are not
- All dogs = an average for all dogs, not this breed
- Not measured = nobody has counted it yet

My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
