The American Bulldog is a loyal and capable dog breed, popular for good reason. But size brings risk - joint problems, ligament tears, and chronic conditions are part of the package. Budget accordingly.
Measured risks
How often they happen is backed by published studies.

Breed study [1] 34.3% of clinically healthy dogs tested were heterozygous carriers of a NIPAL4 gene mutation, out of roughly 800 American Bulldogs screened across North America, Australia and Europe (Casal, Wang, Mauldin, Lin & Henthorn 2017, PLoS One). Carrier frequency, not the rate of clinically affected (homozygous) dogs, which is much smaller.

Not measured Commonly-cited figures (~36% hip, ~20% elbow) trace only to unsourced blog claims attributed vaguely to "OFA" with no evaluation count or date range - no verified OFA figure exists. OFA screening database: 34.7% of 2,503 submitted hip x-rays graded abnormal. Voluntary submissions - true population rate may differ.

Breed study A CTSD gene mutation causes this variant NCL form, clinical onset 1-3 years old with progressive ataxia/paraparesis, first described in a case series of 9 related dogs (JVIM 2005). A DNA test exists commercially, but no published carrier-frequency or population prevalence percentage exists.

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.
