The single biggest decision you will make as a puppy buyer has nothing to do with color, size, or bloodline. It is choosing the right breeder. Everything -- genetics, temperament, health, and the support you get for the life of that dog -- starts with the person who planned the breeding.

Why the Breeder Matters More Than Anything

American Bulldogs are powerful, athletic dogs with strong drives and deep loyalty. In the right hands, they are incredible companions. But when bred carelessly, the results can be devastating -- structural problems, unstable temperament, and heartbreaking health issues that cost thousands of dollars and end lives too soon.

A responsible breeder is not just selling puppies. They are preserving the breed. They know the history of their lines, they test for genetic conditions, and they stand behind every dog they produce. The breeder you choose determines the foundation your dog is built on.

Green Flags: The Breeder Checklist

When evaluating an American Bulldog breeder, look for all of the following. A serious breeder will check every box on this list.

Check the Pedigree Database

One of the easiest ways to verify a breeder's claims is to search for their dogs. The American Bulldog Pedigree Database is the most comprehensive archive of American Bulldog bloodlines in existence. You can search by dog name, kennel name, or registration number.

Look at the pedigree. Are the parents, grandparents, and great-grandparents documented? Can you trace the bloodline back several generations? A breeder who knows their dogs' ancestry and has them recorded in the database is one who takes the breed seriously.

If a breeder's dogs are not in the database, that is a question worth asking. There may be a simple explanation, or it may reveal a lack of transparency.

Ask About COI

COI stands for Coefficient of Inbreeding -- a percentage that measures how closely related a dog's parents are. A lower COI means more genetic diversity, which generally translates to better immune function, fewer inherited diseases, and a longer, healthier life.

Responsible breeders know their dogs' COI and plan breedings to keep it as low as practical. You can check COI values for free using the COI calculator on the pedigree database. If a breeder does not know what COI is or dismisses it, that tells you something important.

Visit the Kennel If Possible

Nothing replaces seeing things in person. When you visit a breeder, pay attention to the details.

A good breeder has nothing to hide. They want you to see their dogs, their setup, and their process. If a breeder will not allow visits or makes excuses, walk away.

Beware the "Just a Pet" Breeder

You will hear this one a lot: "I am not a show breeder -- I just breed pets." That phrase should stop you in your tracks. Every breeding should be intentional. Every pairing should involve health-tested, registered parents with known temperaments and documented pedigrees.

There is no such thing as "just a pet" when it comes to breeding. A puppy from untested parents is a gamble -- and the dog is the one who pays the price when things go wrong. Pet buyers deserve the same quality and care that any buyer does. Your family companion should come from a planned, health-tested breeding. Period.

Red Flags -- Know What to Avoid

  • No health testing or refusal to share results
  • No contract or health guarantee
  • Always has puppies available with no waitlist
  • Will not let you meet the parents or visit
  • Pressures you to buy quickly or offers "discounts" to close the deal
  • Cannot tell you about the dogs' lineage or registration

Frequently Asked Questions

What health tests should an American Bulldog breeder do?

At minimum, both parents should have OFA hip and elbow evaluations, an eye exam (CAER), NCL (Neuronal Ceroid Lipofuscinosis) testing, and ICH (Ichthyosis) testing. A responsible breeder will have documentation for every test and be happy to share results.

Should I worry about the COI of a puppy?

Yes. COI measures how closely related the parents are. A lower COI generally means more genetic diversity and better overall health. Responsible breeders know their dogs' COI and plan breedings accordingly. You can check COI values for free at the American Bulldog Pedigree Database.

Is it a red flag if a breeder has no waitlist?

Not always, but it can be. Good breeders tend to have demand that exceeds supply, which often means a waitlist. If puppies are always available with no wait, it may signal overbreeding or a lack of buyer screening.

What should be in a puppy contract?

A solid contract should include a health guarantee (typically 1 to 2 years), spay/neuter requirements for pet puppies, a return clause requiring the dog be returned to the breeder if the buyer can no longer keep it, and clear terms on registration papers and breeding rights.

Can I verify a breeder's dogs in the pedigree database?

Absolutely. Visit pedigreedatabase.ca and search the breeder's kennel name or individual dogs. You can view pedigrees, verify ancestry, and check COI. If a breeder's dogs are not in the database, that is worth asking about.
