French Bulldogs are extraordinary companions, but understanding the health considerations associated with the breed is an important part of responsible ownership—and responsible breeding.

At Blue Buddha Frenchies, we believe families deserve straightforward information. Health testing can help breeders make more informed decisions and reduce certain risks, but no breeder or genetic test can guarantee that a dog will never experience a health problem.

Here are some of the areas we believe every prospective French Bulldog family should understand.

BOAS and French Bulldog Breathing

BOAS stands for Brachycephalic Obstructive Airway Syndrome, a condition associated with the shortened head and airway anatomy seen in flat-faced breeds such as the French Bulldog.

Not every French Bulldog is affected to the same degree. Breathing function can vary significantly from dog to dog, which is why respiratory assessment is an important consideration when evaluating breeding dogs.

At Blue Buddha Frenchies, BOAS assessment is part of the health information we consider when making breeding decisions.

Families should also understand that noisy breathing should not automatically be dismissed as “normal for a Frenchie.” Changes in breathing, exercise tolerance, heat tolerance, or sleep should always be discussed with a veterinarian.

Why DNA Testing Matters

DNA screening allows breeders to identify genetic variants associated with certain inherited conditions.

Our breeding dogs are screened for conditions including:

Cystinuria Types 2 & 3 — inherited conditions that can contribute to the formation of urinary cystine stones.

HUU — Hyperuricosuria, a genetic condition associated with elevated uric acid in the urine and an increased risk of certain urinary stones.

JHC — Juvenile Hereditary Cataracts, an inherited eye condition that can cause cataracts at a young age.

CMR1 — Canine Multifocal Retinopathy 1, an inherited retinal condition that can cause changes within the eye.

The value of DNA testing is not simply receiving a sheet that says “clear.” The information helps breeders understand the genetic status of individual dogs and make more informed pairing decisions.

Health Testing Is More Than a DNA Panel

Targeted DNA screening is useful, but responsible health evaluation should not be viewed as a single test or checklist.

At Blue Buddha Frenchies, every breeding parent also receives a veterinarian-performed physical evaluation of the hips and patellas and a BOAS assessment. Breeding decisions consider the whole dog, including respiratory function, physical structure, temperament, pedigree, veterinary history, and available health information.

That broader picture matters because many health conditions are influenced by more than a single identifiable gene.

Structure Matters

French Bulldogs have a distinctive build, and thoughtful structure is about much more than appearance.

Breeders should consider balance, movement, overall physical soundness, and whether a dog's structure supports comfortable everyday life.

At Blue Buddha, structure is considered alongside health and temperament when evaluating our dogs and planning future generations.

Temperament Is Part of Health, Too

A beautiful dog should also be capable of becoming a wonderful companion.

We place significant value on temperament because our puppies ultimately live as members of families. Confidence, adaptability, sociability, and the ability to comfortably interact with people and normal household life all matter.

Those qualities are influenced by both genetics and the environment puppies experience during their earliest weeks.

The Importance of Early Puppy Raising

Health does not stop with genetics.

From birth through go-home day, puppies benefit from attentive care, proper nutrition, veterinary oversight, cleanliness, early socialization, and gradual exposure to the sights, sounds, handling, and routines of everyday family life.

At Blue Buddha Frenchies, our puppies are raised in our home and introduced to litter box training before leaving for their new families.

What Puppy Families Should Ask a Breeder

When speaking with a French Bulldog breeder, families should feel comfortable asking questions.

Ask what health testing is performed on the parents. Ask why a particular pairing was chosen. Ask about breathing, temperament, veterinary care, how the puppies are raised, and what support is available after the puppy goes home.

A responsible breeder should be willing to discuss both the wonderful qualities of the French Bulldog and the health considerations that come with the breed.

Health Testing Reduces Risk—It Does Not Eliminate It

This may be the most important point.

Health testing gives breeders information. Careful selection gives breeders information. Pedigree history gives breeders information.

Together, those tools help us make more thoughtful decisions, but biology never comes with an absolute guarantee.

Our responsibility at Blue Buddha Frenchies is to use the information available to us, continue learning, make breeding decisions thoughtfully, and be transparent with the families who trust us.

The Blue Buddha Approach

Our program is built around veterinarian-performed physical evaluations of the hips and patellas, BOAS assessment, targeted DNA screening, thoughtful pairings, family raising, and generations of firsthand experience with our own Blue Buddha bloodlines.

We believe responsible breeding is a process—not a slogan.

For families considering a French Bulldog, we encourage you to learn about the breed, ask questions, meet the dogs behind a breeding program, and choose a breeder whose philosophy aligns with the kind of lifelong companion you hope to welcome into your family.
