American Bulldog Health Screening: What Owners and Puppy Buyers Should Know

Key takeaways

Ask for verifiable health-test results, not only a statement that the parents are “vet checked.”
Hip and elbow evaluations matter in a large, powerful breed that puts significant load through its joints.
DNA testing can identify specific inherited variants, but a DNA panel is not a substitute for orthopedic and cardiac evaluation.
Use screening results as one part of a broader decision that also includes temperament, structure, living conditions and veterinary history.

Why health screening matters for this breed

American Bulldogs are strong working-type dogs. Their build can hide early orthopedic discomfort because many dogs remain enthusiastic and active even when a joint is not moving normally. A responsible screening plan tries to identify inherited or developmental risk before breeding and gives owners a baseline to discuss with their veterinarian.

The Orthopedic Foundation for Animals (OFA) maintains public databases for many canine health evaluations, including hips, elbows, cardiac examinations and DNA-based tests. When a breeder says a dog has been health tested, ask which tests were performed, at what age, by whom, and whether the results can be independently verified.

The core areas to discuss

Hips and elbows. Hip and elbow dysplasia are among the orthopedic concerns commonly discussed for American Bulldogs. Formal imaging-based screening is different from a routine wellness exam because the images are positioned and evaluated specifically for joint conformation.Cardiac evaluation. A heart exam can help identify murmurs or other findings that deserve further workup. OFA maintains basic and advanced cardiac databases; an advanced exam includes echocardiography.Breed-relevant DNA tests. OFA lists a DNA test for neuronal ceroid lipofuscinosis, American Bulldog type (NCL 10), and also accepts results for ichthyosis. Ask a veterinarian or genetics professional how a particular result should influence breeding or health decisions.

How to read a breeder’s paperwork

Do not rely on screenshots with no registration information. Match the registered name or number to the dog you are considering, confirm the test date, and check whether the result is preliminary or final. A result on one parent does not automatically tell you the status of the other parent.

A long list of genetic panel results can look impressive, but relevance matters more than volume. Ask why each test was chosen and which breed-specific conditions the breeder is trying to reduce. The goal is thoughtful selection, not collecting the largest number of certificates.

Questions worth asking before you commit

Can I see the registered names and health-test results for both parents?
Were hips and elbows evaluated after the appropriate age for the registry?
Was a cardiac exam performed, and what type?
Which inherited conditions are known in your lines?
Have close relatives had orthopedic, skin, neurologic or cardiac problems?
What support will you provide if a health issue appears later?

What screening cannot tell you

Health testing reduces uncertainty; it does not eliminate it. Joint disease is influenced by genetics, growth, body condition, activity and injury. Skin disease can have multiple causes. A dog with clear DNA results can still develop unrelated medical problems.

Treat screening as a better starting point, then continue with routine veterinary care, sensible conditioning, weight management and prompt evaluation of new symptoms.

When to call your veterinarian

This guide is general education. New pain, collapse, breathing difficulty, neurologic signs, persistent lameness, rapid weight change or worsening skin disease should be assessed by a veterinarian rather than managed from an article.
