French Bulldog Health Issues: What Every Owner Should Know
Updated: 5 days ago
By Nick, co-founder of Doggy Styles Inc and owner of Bruno, a rescued French Bulldog. Last updated 11 October 2026.
Quick Answer
French Bulldogs are prone to more health problems than most breeds, mainly because of their flat faces. The big ones are breathing problems (BOAS), overheating, skin and ear problems, back problems and difficult births. In the largest UK study, Frenchies had a higher risk than other dogs for 20 of 43 common conditions. Most of the risk can be reduced: choose carefully, keep them lean and cool, and learn the warning signs.
Key takeaways
Breathing is the biggest issue. Snoring and snorting are signs of a narrowed airway, not just personality.
Skin, ears and allergies are the everyday problems. Diet can make a real difference.
Heat and back injuries are the emergencies to know. Learn the signs before you need them.

Are French Bulldogs unhealthy? The common misconception
There are two myths. One says Frenchies are basically healthy and the snoring is just character. The other says they're so unhealthy nobody should own one. Neither helps. The truth is that the breed has real, well-documented health risks, and that owners who understand them can do a great deal to protect their dog.
The first sign
He's a few months old, and he snores. Loudly. Everyone thinks it's hilarious: the little old man noises, the snuffling, the grunts when he settles. You film it for your family. Months later, a vet listens to his chest, watches him breathe, and asks how loud he is at night. That's the first time you wonder whether the soundtrack means something.
Common French Bulldog health problems at a glance
Condition | What you might notice | How serious |
Heatstroke or a breathing crisis | Heavy panting that won't settle, noisy laboured breathing, blue or grey gums, collapse | Emergency: cool down and get to a vet now |
Back problems (IVDD) | Yelping, reluctance to move or jump, wobbly back legs, dragging feet | Urgent: same-day vet |
Breathing problems (BOAS) | Snoring, snorting, struggling on walks, noisy breathing at rest | Lifelong: needs vet monitoring |
Skin fold infections and allergies | Itching, redness, smell, licking paws, flaky or greasy skin | Common: manageable with care and diet |
Ear problems | Head shaking, scratching, discharge, smell | Common: treat early |
Eye problems (cherry eye, ulcers) | Red lump in the eye corner, squinting, weeping | See a vet promptly |
Digestive problems | Regurgitation, vomiting, wind | Often linked to breathing; worth raising with your vet |
Why do French Bulldogs have so many health problems?
The flat face
Almost everything comes back to the shape of the head. A short skull leaves less room for the soft tissue of the nose and throat, so the airway is narrow. That makes breathing harder work, makes cooling down harder (dogs cool themselves by panting), and puts strain on the whole body.
What the research says
In 2021, Royal Veterinary College researchers compared vet records for 2,781 French Bulldogs with 21,850 other dogs (O'Neill and colleagues, 2021). Frenchies had a higher risk for 20 of 43 common conditions. The biggest differences were narrowed nostrils (42 times the odds), BOAS (31 times), ear discharge (14 times), skin fold infections (11 times) and difficult births (9 times). The authors called these "ultra-predispositions". The Frenchies in the study were young, too, so problems that appear with age may be under-counted.
Owners often don't see it
This is the part that worries vets most. In an RVC study, 58% of owners whose dogs had BOAS said their dog had no breathing problem (dvm360, reporting Packer and colleagues). When you live with the snoring every day, it starts to sound normal.
How these problems add up over a lifetime is covered here.
👉 HOW LONG DO FRENCH BULLDOGS LIVE? — What the Studies Actually Say
Every Frenchie owner knows the worry that comes with the love. The snoring you listen to at night. The extra care on warm days. The vet bills you'd pay ten times over. It's part of the deal, and most owners wouldn't change a thing.
That's the dog Doggy Styles Inc is built around: real dogs, and the people who look after them.

French Bulldog breathing problems (BOAS)
Brachycephalic obstructive airway syndrome, or BOAS, is the narrowing of the airway caused by the flat face: pinched nostrils, a long soft palate and a narrow windpipe. The University of Cambridge's BOAS research group says that "respiratory noises such as snoring and snorting are indicators of airway obstruction", and that dogs with moderate to severe nostril narrowing are about 20 times more likely to develop BOAS (University of Cambridge).
Signs include loud snoring, snorting, noisy breathing when awake, struggling on walks, collapsing after exercise and difficulty eating. Battersea notes that "surgery can help some dogs breathe more comfortably, but BOAS cannot be cured" (Battersea). Keeping your Frenchie lean helps: Cambridge research found obesity was a risk factor.
Breathing also sets the limit on how much exercise a Frenchie can do.

Heat: the hidden danger
Because they can't pant efficiently, Frenchies overheat quickly. An RVC study found French Bulldogs were six times as likely as Labradors to suffer heat-related illness (RVC VetCompass). Most cases follow exercise, not hot cars. On warm days: short walks, early or late, shade, water, and a cool floor to lie on.
French Bulldog skin problems and allergies
Skin is where most owners notice trouble day to day: itchy paws, red skin folds, ear infections, a yeasty smell. Skin folds trap moisture, and many Frenchies have allergies.
Our Frenchie, Bruno, is a case in point. Before we rescued him, he'd been kept in a wire cage about three and a half feet by two, with a tray underneath that he had to use as a toilet. When we got him he was pretty much without hair and full of infections, bacterial and yeast. Skin has been the main battle ever since. Our vet has been brilliant, but it took round after round of antibiotics. Then we started looking carefully at his diet. Within a few weeks we could see the difference, and there was no turning back. He now has diet and skin supplements, and his coat has come back.
Every dog is different, and diet won't fix everything. But if your Frenchie is constantly itching, ask your vet about allergies and diet before you assume it's just the breed.
How Bruno's personality came out as his health recovered is part of a post of its own.

The turning point
You've been back to the vet three times in two months. Another course of antibiotics, another cone, another week of him scratching at night. Then the vet suggests trying a new diet, properly, with nothing else on the side. You weigh every portion and say no to every pleading look at the dinner table. Four weeks later you notice he hasn't scratched all evening. Six weeks later, there's soft new fur where the bald patches were.
Clean skin folds gently and keep them dry, check ears weekly, and keep an eye on paws. PDSA advises keeping folds "clean and dry" (PDSA).
French Bulldog back problems (IVDD)
Frenchies have short, curved spines, and Battersea describes them as "at high risk" of intervertebral disc disease (IVDD), where a disc in the spine bulges or ruptures. One study found Frenchies with spinal curvature (kyphosis) had about twice the odds of disc extrusion (Inglez de Souza and colleagues, 2018). Signs include sudden pain, yelping, a hunched back, reluctance to jump or climb stairs, wobbliness and dragging back legs. Treat any of these as urgent.
Sudden refusals to walk or jump are sometimes mistaken for stubbornness. They're worth checking.

Eyes, ears and other common problems
Eyes: cherry eye (a red swelling in the corner of the eye), corneal ulcers, dry eye and cataracts.
Ears: narrow ear canals make ear discharge and infections common. Watch for head shaking and smell.
Digestion: regurgitation and vomiting are often linked to breathing problems in flat-faced dogs.
Births: most Frenchie litters are delivered by caesarean. In one study, 81% were.
The PDSA also lists luxating kneecaps, crowded teeth and urinary stones among the breed's problems.
How to keep a French Bulldog healthy
Choose carefully. If you're buying a puppy, ask whether the parents have been breathing-tested under the Kennel Club's Respiratory Function Grading scheme, and look for open nostrils.
Keep them lean. Extra weight makes breathing, backs and joints worse.
Keep them cool. Short walks, early or late, in warm weather.
Look after skin and ears. Clean folds gently and dry them, check ears weekly, and take itching seriously.
Insure early. PDSA estimates the lifetime cost of a Frenchie at "over £12,000", before vet bills.
Listen to the breathing. Mention snoring and noisy breathing at every vet visit.
When to see a vet: get help immediately for heavy panting that won't settle, noisy or laboured breathing, blue or grey gums, collapse, or sudden back pain, wobbliness or loss of use of the legs. See your vet promptly for eye problems, persistent itching, ear discharge, repeated vomiting or regurgitation. This post isn't veterinary advice.
French Bulldog health compared with other breeds
Frenchies share most of their problems with the other flat-faced breeds. English Bulldogs have similar breathing issues and were 14 times as likely as Labradors to suffer heat-related illness in the same RVC study. Pugs have similar breathing and eye problems. Breeds with longer noses, such as Labradors, have different issues (joints, weight) but far fewer breathing problems. If good health is your top priority, a flat-faced breed asks more of you.
Health is a big part of whether a Frenchie suits your household.

What owners learn
Most owners learn to watch their Frenchie the way you'd watch anyone you love: the breathing at night, the scratching, the way they move on the stairs. It becomes second nature. And they learn that a lot of good health is in their hands: the weight, the walks, the food, the early vet visit.
The settled routine
Two years on. He's lean, his coat is thick, and his skin is calm. He has two short walks a day, never in the afternoon heat, and his food is measured to the gram. You still listen to him snore at night. But now you know what normal sounds like for him, and you'd know straight away if it changed.
The verdict
What health issues do French Bulldogs have? More than most breeds: breathing problems, heat sensitivity, skin and ear problems, back problems and difficult births lead the list. But knowing them is most of the battle. Choose carefully, keep them lean and cool, take the snoring seriously, and act fast on the warning signs. Do that, and you give them the best chance of a long, comfortable, very snory life.

FAQs
What are the most common French Bulldog health problems?
Breathing problems (BOAS), overheating, skin fold infections and allergies, ear problems, eye problems such as cherry eye, back problems (IVDD) and difficult births. A UK study found Frenchies at higher risk than other dogs for 20 of 43 common conditions.
Are French Bulldogs unhealthy dogs?
They have more inherited health risks than most breeds, mostly because of their flat faces. Many Frenchies live comfortable lives, but they need careful buying, weight control, heat care and regular vet checks.
How can I tell if my French Bulldog has breathing problems?
Loud snoring, snorting, noisy breathing when awake, struggling on short walks, needing long recovery after exercise and difficulty eating are all signs. Ask your vet to assess your dog's breathing, even if it seems normal to you.
Can BOAS be fixed with surgery?
Surgery to widen the nostrils or shorten the soft palate can help many dogs breathe more comfortably, but BOAS can't be cured. Keeping your dog lean and cool still matters after surgery.
Why does my French Bulldog keep scratching?
Allergies, skin fold infections, yeast and parasites are common causes. Persistent itching needs a vet visit. Ask about diet and allergies too: for some Frenchies, a change of food makes a big difference.
Are French Bulldogs prone to back problems?
Yes. Battersea describes them as at high risk of intervertebral disc disease (IVDD). Sudden pain, reluctance to move, wobbliness or weak back legs should be treated as urgent.
Why do French Bulldogs get ear infections?
Their narrow ear canals trap wax and moisture. An RVC study found Frenchies had about 14 times the odds of ear discharge compared with other dogs. Check and clean ears gently, and see a vet if they smell or your dog shakes their head.
What is cherry eye in French Bulldogs?
A red, swollen lump in the inner corner of the eye, caused by the tear gland slipping out of place. It's common in flat-faced breeds and usually needs a vet's treatment, often surgery.
How much do French Bulldog vet bills cost?
It varies widely, but health problems can be expensive. The PDSA estimates a Frenchie's lifetime cost at over £12,000 before vet treatment. Insuring from puppyhood is strongly recommended.
How do I choose a healthy French Bulldog puppy?
Look for visibly open nostrils, a moderate build and a breeder who has had the parents breathing-tested under the Kennel Club's Respiratory Function Grading scheme. Avoid "rare" colours and extreme looks, and ask about the parents' health history.
