The American Bulldog is a large, athletic, muscular dog descended from the working bulldogs of colonial America. It is mostly white, often with patches of brindle, red, brown or fawn, and has a short, harsh coat. Two broad types are seen: the leaner, longer-muzzled 'Standard' or Scott type and the heavier 'Bully' or Johnson type. It is a separate breed from the American Bully.

Lifespan

0Senior ≈ 720 yrs

Most American Bulldogs live 10–15 years. Like other large dogs, they're usually considered senior from about 7, when twice-yearly vet checks help catch problems early. Keeping them lean is one of the most effective things you can do for a long life. How old is that in human years?

Temperament

American Bulldogs are usually confident, loyal and very attached to their families, with a natural protective streak. Some can be wary of strangers or intolerant of other dogs, especially of the same sex, so early socialisation and steady handling are important.

  • Most adults do well on two measured meals a day rather than one large one.
  • Puppies of large breeds need a diet made for large-breed growth, so they grow steadily rather than fast.
  • Choose a complete food for their life stage, and ask your vet before changing diet if they have a health condition.

Starting points only — age, activity and the food itself change the numbers. Work out portions for your dog · Foods to avoid

Exercise

90–120 min a day

A strong, energetic dog that needs at least an hour of exercise a day, ideally mixing walks with play, tug games or structured activities. Take care in hot weather, particularly with shorter-muzzled dogs.

Grooming & shedding

The short coat needs only a weekly brush. Check the skin regularly, as the breed is prone to skin problems.

Health

Its size, power and guarding instinct make reward-based training from puppyhood essential. Check local rules before getting one, as bulldog and bully types can be subject to restrictions in some places. See a vet for persistent itching, skin sores or lameness.

The breed can be prone to

  • Neuronal ceroid lipofuscinosis (NCL)
  • Ichthyosis
  • Allergic skin disease
  • Juvenile-onset demodicosis
  • Hip and elbow dysplasia
  • Cranial cruciate ligament rupture

Health tests to ask a breeder about

  • Hip and elbow scoring
  • NCL DNA test
  • Ichthyosis DNA test

Not every American Bulldog is affected, and this isn't a diagnosis. See common conditions and the symptom checker.

History

Bulldog-type dogs came to the American colonies with British settlers and worked on farms as guards, stock dogs and catch dogs for cattle and hogs. After the Second World War they were close to disappearing, but John D. Johnson and Alan Scott gathered surviving dogs from Southern farms and rebuilt the breed, giving rise to the two main types. The UKC recognised the breed in 1999, and the AKC added it to its Foundation Stock Service in 2019.
