TL;DR
The typical French Bulldog lifespan is about 9 to 10 years, one of the shortest of any popular breed. In a 2024 UK study of 584,734 dogs, French Bulldogs had a median lifespan of 9.8 years, against 12.0 years for mixed breeds. Their flat faces drive most of their health problems: compared with other dogs, French Bulldogs had 42 times the odds of narrowed nostrils and 31 times the odds of brachycephalic obstructive airway syndrome (BOAS), and in US data they had 21 times the odds of owner-reported disc disease. Ear infections (14.0%) were the most common problem in a single year. A French Bulldog is a senior from about 7.4 years.
How long do French Bulldogs live?
| Measure | French Bulldog | Mixed breed |
|---|---|---|
| Median lifespan, 2024 UK study (2,495 deaths) | 9.8 years | 12.0 years |
| 95% confidence interval | 9.4 to 10.1 years | 12.0 to 12.1 years |
| Life expectancy at birth, UK life tables | 4.53 years | 11.82 years |
| Senior from about (last 25% of lifespan) | 7.4 years | 9 years |
The very low life expectancy at birth in UK life tables (the lowest of 18 common breeds) partly reflects how young the breed's population is: the share of UK puppies that were French Bulldogs rose from 0.02% in 2003 to 1.46% in 2013, and in 2013 the median French Bulldog was just 1.3 years old, so many deaths recorded were of young dogs. The 2024 median of 9.8 years is a better guide to how long a French Bulldog that reaches adulthood can expect to live.
French Bulldog age in human years
| Dog's age | Life stage | Roughly like a person aged |
|---|---|---|
| 4 years | Mature adult | 32 |
| 5 years | Mature adult | 40 |
| 6 years | Mature adult | 48 |
| 7 years | Mature adult | 56 |
| 8 years | Senior | 64 |
| 9 years | Senior | 73 |
| 10 years | Senior, past the median | 81 |
| 11 years | Senior, past the median | 89 |
| 12 years | Senior, past the median | 97 |
| 13 years | Senior, past the median | 105 |
This uses the share of the breed's typical lifespan a dog has lived, compared with US human life expectancy of 79 years. For puppies and young dogs, the DNA-based method in the calculator below is more accurate. Try any age:

Your dog has lived about 67% of the typical 12.0-year lifespan for this group. The same share of a 79.0-year US life expectancy is age 53.
Life stage
Mature adult
AAHA: from maturity until the last 25% of expected lifespan, about 9.0 years for this group.
Mixed breed (crossbreed): median lifespan 12.0 years (95% CI 12.0 to 12.1), senior from about 9.0 years.

French Bulldog health problems
Breathing (BOAS)
In a UK study comparing 2,781 French Bulldogs with 21,850 other dogs, French Bulldogs had higher odds of 20 of 43 common disorders. The strongest were:
| Disorder | Odds compared with other dogs |
|---|---|
| Narrowed nostrils (stenotic nares) | 42.14 times |
| Brachycephalic obstructive airway syndrome | 30.89 times |
| Ear discharge | 14.40 times |
| Skin fold dermatitis | 11.18 times |
| Difficult birth (dystocia) | 9.13 times |
BOAS causes noisy breathing, snoring, poor exercise tolerance and a high risk of overheating. Surgery to widen the nostrils and shorten the soft palate can help many dogs.
What our founder learned from seven pugs
Pugs share the same flat-faced build, and our founder Morty has raised seven of them.
- Snoring is normal life. Almost every night, nearly 100% of the time. Morty got so used to it that the sound became a comfort.
- Heat is the real danger. On one daytime walk a pug stopped, panting hard, close to heatstroke. Rest in the shade and a drink of water brought it round. Since then: short summer walks in the cool of the day, and never running together.
- Cold matters too. In winter Morty's pugs wore coats, and each change of season brought a run of colds.
If a flat-faced dog is still panting hard after resting in the shade, or wobbles, vomits or collapses, treat it as heatstroke and go to a vet straight away.
Back problems
French Bulldogs are prone to intervertebral disc disease. In the US Dog Aging Project study of 43,517 dogs, French Bulldogs had 21.1 times the odds of owner-reported disc disease, the highest of any purebred. Sudden back pain or weak back legs is an emergency. See dog wheelchairs for back legs.
Ears, skin, eyes and gut
In the 2013 UK study of 2,228 French Bulldogs, the most common problems were ear infections (14.0%), diarrhea (7.5%), conjunctivitis (3.2%), overlong nails (3.1%) and skin fold dermatitis (3.0%). By group, skin (17.9%), gut (16.7%), ear (16.3%), upper airway (12.7%) and eye problems (10.5%) were most common.
How to help a French Bulldog live longer
- Keep it lean. Extra weight makes breathing, heat tolerance and the spine all worse. See senior dog food for weight loss.
- Avoid heat: walk in the cool of the day, never leave it in a car, and watch for heavy panting or collapse.
- Use a harness, not a collar, to keep pressure off the airway.
- Ask your vet about BOAS surgery if your dog snores loudly, struggles on walks or overheats easily.
- Protect the back: ramps instead of jumping, and act fast on back pain. Keeping muscles strong helps; our Muscle Strength & Recovery Soft Chews provide 150 mg calcium HMB and 160 mg L-leucine per serving.
- Clean ears and skin folds regularly. See senior dog grooming.
- Twice-yearly vet checks from about 7.4 years.
FAQ
How long do French Bulldogs live?
Most French Bulldogs live about 9 to 10 years. A 2024 UK study of 584,734 dogs found a median lifespan of 9.8 years, one of the shortest of the breeds studied.
Why do French Bulldogs have a short lifespan?
Mainly because of their flat-faced build. They have about 31 times the odds of brachycephalic obstructive airway syndrome and very high odds of narrowed nostrils, skin fold infections and disc disease compared with other dogs.
Is 8 old for a French Bulldog?
Yes. A French Bulldog is a senior from about 7.4 years, and at 8 it has lived about 82% of the breed's median lifespan, roughly like a person aged 64.
What health problems do French Bulldogs have?
Breathing problems (BOAS and narrowed nostrils), ear infections, skin fold infections, eye problems, diarrhea and disc disease are the most common.
How can I help my French Bulldog live longer?
Keep it lean, protect it from heat, use a harness, ask about BOAS surgery if it struggles to breathe, and protect its back.
