How long do American Bulldogs live?
In a 2022 study of UK vet records, American Bulldogs had a life expectancy at birth of 7.79 years. The Tailmates longevity score starts an American Bulldog from the large-breed curve: typically 10.3–12.7 years. Always a range, never a date.
The first figure is the study’s own (Teng et al. 2022). The range comes from the large-breed curve, where the Tailmates longevity score starts. Senior is the AAHA guideline that a dog enters its senior years in the last quarter of its typical lifespan, a size-band guide your vet tailors to your dog.
What studies found for American Bulldogs
Each figure is the study’s own, as published. Studies count lifespan in different ways, so their figures differ from each other and from the large-breed range above.

Already 2+ years old? The outlook is better than subtraction.
These numbers are conditional on the age your dog has already reached. A dog who’s made it to midlife has cleared the early risks that pull the breed average down. So the honest answer is more than “lifespan minus age.”

How much should you walk an American Bulldog?
Around 60–120 minutes a day, ideally with some brisk, purposeful stretches.
Band-level guidance, not a prescription. Age, health, and your vet’s advice come first.
What daily walks do to the longevity math
In the Tailmates model, a 28-day rolling window of active minutes feeds a saturating curve, the first minutes matter most, and it moves the estimate up by at most +0.5 years, never down. Bounded on purpose: activity has no published year-delta, sick dogs simply move less, and a walk you forgot to log looks exactly like a walk you never took. For a steady daily habit:
The bigger walking payoff is indirect: lean body condition, the strongest modifiable lever in the model. For a large breed like the American Bulldog, ideal body condition reads +0.5 yr (capped at the +1.8-year effect from the Kealy lean-feeding trial), while carrying extra weight reads -0.7 yr and obesity -1.3 yr. Daily walks are how most dogs stay on the right side of that line.
