The Boston Terrier is charming and full of personality, but that flat face isn't just cosmetic. Breathing problems, spinal disease, and skin issues are practically guaranteed. This is one of the most expensive breeds to own.
No breed-specific studies yet - unranked. Missing data is not low risk.
Measured risks
How often they happen is backed by published studies.
What is this?Hide
All dogs 12.58% one-year period prevalence of any skin disorder, all UK dogs (O'Neill et al. 2021, BMC Veterinary Research)
Chronic skin inflammation causing persistent itching. No Boston Terrier-specific figure was confirmed - and unlike English Bulldog, French Bulldog and Pug, Boston Terrier wasn't named in the dedicated skin-fold dermatitis study, suggesting its folds are less pronounced. Full profile →
What is this?Hide
All dogs 12.52% one-year recorded-diagnosis prevalence, all UK dogs (O'Neill et al. 2021, JSAP); prospective exams find 44-64%
Bacteria from infected teeth and gums can affect more than just the mouth. This is an all-dogs baseline, not a Boston Terrier-specific study. Full profile →
What is this?Hide
All dogs 7.30% one-year period prevalence, all UK dogs (O'Neill et al. 2021, Canine Medicine and Genetics)
Recurring bacterial or yeast infections in the ear canal. No Boston Terrier-specific figure was confirmed. Full profile →
What is this?Hide
All dogs 7.07% one-year recorded-diagnosis prevalence, all UK dogs (O'Neill et al. 2021, BMC Vet Res); when actually weighed, about 59% are overweight or obese
Excess body weight straining joints and organs. No Boston Terrier-specific figure was confirmed - this is the all-dogs baseline. Full profile →
What is this?Hide
Body type Brachycephalic breeds as a group: odds ratio 11.18 (8.72-14.32), prevalence 3.76% (3.30-4.25) vs non-brachycephalic dogs; Boston Terrier didn't have enough individual cases to be broken out separately (O'Neill et al. 2017, Canine Genetics and Epidemiology)
Prominent eyes on a flat face scratch and ulcerate easily. Boston Terrier wasn't broken out individually in the largest study of this condition, but the grouped brachycephalic-breed rate is well above average. Full profile →
Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
Not measured No confirmed Boston Terrier-specific prevalence found; OFA screening database: 12.5% of 598 submitted hip x-rays graded abnormal. Voluntary submissions - true population rate may differ.
A malformed hip joint. No Boston Terrier-specific study was found - health screening in this breed tends to focus on eyes, patella and airway rather than hips. Full profile →
What is this?Hide
Not measured Boston Terrier does not appear in the breed table or multivariable model of the primary VetCompass patellar luxation study (O'Neill et al. 2016, Canine Genetics and Epidemiology) - all-dogs baseline is 1.30%; OFA screening database: 4.9% of 5,410 submitted patella exams graded abnormal. Voluntary submissions - true population rate may differ.
The kneecap slips out of place. Despite this being a small breed, the largest population study of this condition doesn't list Boston Terrier among the significantly affected breeds. Full profile →

Breed study 37.5% of Boston Terriers graded as unaffected (Grade 0) vs only 10% of French Bulldogs in a direct breed comparison (p<0.001) - meaning roughly 62.5% show at least some grade of airway obstruction, though typically milder than French Bulldog/Pug/Bulldog (Tomlinson et al. 2024, PLoS ONE)
Brachycephalic obstructive airway syndrome - the flat face narrows the airway. Boston Terrier shows a milder pattern than French Bulldog or Pug, but a majority still show some grade of obstruction. Full profile →
What is this?Hide
Not measured Named only as historically suspected in the introduction of the largest VetCompass study of this condition (O'Neill et al. 2022, PLoS ONE) - didn't meet the case-count threshold for its own breed-specific odds ratio
The third eyelid gland prolapses into a red, swollen mass. Boston Terrier is historically listed as a suspected breed, but the largest population study of this condition didn't have enough confirmed Boston Terrier cases to calculate a real breed-specific rate. Full profile →
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.
