Most French Bulldogs cannot breathe, cool themselves, or give birth the way a normal dog can — the flat face that defines the breed causes lifelong airway restriction, and real-world veterinary data puts their median lifespan noticeably below the typical dog's.
9.8years, median
2.7 years below the all-dog median of 12.5.
Measured, not estimated: the middle age at death across 584,734 UK dogs, 284,734 of them deceased. Based on 14,316 dogs of this breed. 95% confidence interval 9.4 to 10.1 years. Half lived longer than this, half did not. UK dogs, so treat it as the best available figure rather than a promise about yours.
In the same study, small breeds as a group had a median of 12.7 years and flat-faced breeds 11.2. This breed is small and flat-faced.
McMillan et al. 2024, Scientific Reports 14:531 — open access · CC BY 4.072.4% of French Bulldogs had at least one disorder recorded in 2013.
From the clinical records of 2,228 French Bulldogs under veterinary care in the UK that year, read by the Royal Veterinary College’s VetCompass programme.

|---|---|---|
| Ear infection (otitis externa) | 14% | 12.6–15.5 |

| Conjunctivitis | 3.2% | 2.5–4.0 |

| Skin fold dermatitis | 3% | 2.3–3.8 |
| Anal sac impaction | 2.9% | 2.2–3.7 |
| Upper airway infection | 2.7% | 2.1–3.5 |
| Skin infection (pyoderma) | 2.7% | 2.1–3.5 |
| Cherry eye | 2.6% | 1.9–3.3 |
| Inflamed paws (pododermatitis) | 2.5% | 1.9–3.2 |
| Obstructed breathing (BOAS) | 2.4% | 1.8–3.2 |
Compared with other dogs, 2016
2,781 French Bulldogs against 21,850 other dogs. The odds of having at least one disorder that year were 0.89 times those of other dogs (95% CI 0.82 to 0.97), a young-population effect explained below. Of 43 disorders tested, 20 were more common in the breed and 11 less common.

Age at death in this sample
Median 3.6 years (middle half 1.8 to 6.1), 2013 data. Of the 84 deaths with a recorded cause: Brain disorder 11.9%, Spinal cord disorder 9.5%, Lower airway disorder 7.1%, Lump (mass) 7.1%, Upper airway disorder 7.1%. Not a lifespan. In 2013 the breed was booming and most French Bulldogs were puppies, so the dogs that died that year were mostly young. The measured-lifespan figure above is the one to use. Different sample and year from the measured lifespan above, which is why the two numbers differ.
The slightly lower odds of any disorder at all (0.89) is a young-population effect: the 2016 French Bulldogs had a median age of 1.5 years against 4.5 for the other dogs. The list of what they get more of is the useful part.
“French Bulldogs should, in many respects, no longer be considered as an 'average' or 'typical' dog.”— the authors, O'Neill et al. 2021, Canine Medicine and Genetics 8:13
Health tests to ask the breeder for
French Bull Dog Club of America sets the tests a French Bulldog needs for a CHIC number in the OFA's open database. A CHIC number means the tests were done and the results are public. It does not mean the dog passed them: ask for the results for both parents, or look them up yourself on ofa.org.
- Hip Dysplasia (OFA Evaluation, OVC Evaluation or PennHIP Evaluation)
- Eye Examination by a boarded ACVO Ophthalmologist (annual recertification recommended)
- Patellar Luxation (OFA Evaluation)
- Congenital Cardiac (OFA Evaluation; echocardiogram recommended but not required)
When to spay or neuter: the guidelines split at 45 pounds grown, five to six months under it and after growth is complete over it, and the UC Davis study gives a guideline by breed for 35 breeds. The spay and neuter page has both, and the two weeks after.
Eye ulcers: flat-faced breeds as a group had over 11 times the risk of crossbred dogs in a study of more than 100,000 dogs in England. A squint or a half-closed eye is a same-day call to the vet. The eye ulcer page has the signs, and the eye drops that make an ulcer worse.
- Autoimmune Thyroiditis (OFA evaluation)
- Juvenile Cataracts (HSF4) DNA test

Living with a French Bulldog
Frenchies are affectionate, low-exercise companions that do well in apartments, but that's largely a side effect of a body that overheats and struggles for air rather than genuine laziness — heat and strenuous exercise are both real risks, air travel is restricted by many airlines, and prospective owners should budget for a real chance of airway surgery and a planned C-section delivery if breeding. Snoring and snorting are constant, not occasional.
Health you should know about
- Brachycephalic Obstructive Airway Syndrome (BOAS) — narrowed nostrils, an elongated soft palate and a narrow windpipe together restrict airflow; RVC research lists breathing problems among the breed's top health conditions, and many affected dogs eventually need corrective surgery.
- Shortened lifespan — a large UK veterinary-records study found French and English Bulldogs had a median lifespan of around 9.8 years, versus about 12.5 years for dogs generally.
- Very high Caesarean-section rate — a peer-reviewed study of UK litters found the C-section rate in French Bulldogs exceeded 80%, among the highest of any breed, largely because puppy head width often exceeds what the mother can deliver naturally.
- Skin-fold dermatitis, cherry eye and corneal ulcers — recurring conditions tied to the breed's facial and skin conformation, all flagged as common in RVC's health surveys of the breed.
