The Dogue de Bordeaux — also known as the French Mastiff — is a loyal, loving giant with a heart as big as its powerful frame. Weighing up to 160 pounds, these dogs are gentle with their families and deeply devoted companions.
But here’s the hard truth every owner needs to face: the Dogue de Bordeaux has a relatively short lifespan, typically 6 to 8 years. And like many large breeds, they are prone to specific genetic and disease-related health challenges.
The good news? Forewarned is forearmed. By understanding the most common causes of mortality in this breed, you can take proactive steps to help your Dogue live a longer, healthier, and happier life.
In this post, we’ll walk through the top five health concerns for the Dogue de Bordeaux — and exactly what you can do about each one.
At a Glance: Top 5 Health Risks for Dogue de Bordeaux
| Health Issue | Approx. Risk Level | Key Prevention |
|---|---|---|
| Cancer | ~30% of deaths | Regular vet checks, antioxidants |
| Heart Disease | ~4.7% diagnosed | Screenings, low-sodium diet |
| Hip Dysplasia | 25–47% prevalence | OFA-certified parents, joint supplements |
| Bloat (GDV) | High (deep-chested) | Slow feeders, gastropexy surgery |
| Brachycephalic Syndrome | Common | Weight control, avoid heat |
1. Cancer: The Silent Threat (Responsible for ~30% of Deaths)
What you need to know:
Cancer is the leading cause of death in the Dogue de Bordeaux, accounting for approximately 30% of mortality in the breed. The most common types include lymphoma and mast cell tumors.
These cancers can develop quickly, but early detection makes a real difference.

How to Reduce Cancer Risk in Your Dogue de Bordeaux
- Routine veterinary check-ups – Schedule exams every 6–12 months to catch lumps, bumps, or behavioral changes early.
- High-quality, antioxidant-rich diet – Support immune function with fresh, balanced nutrition.
- Limit toxin exposure – Reduce contact with pesticides, herbicides, and household chemicals.
- Discuss spay/neuter timing – Work with your vet to choose the best age to lower hormone-related cancer risks.
2. Heart Disease: When a Big Heart Has Big Problems (≈4.7% of Cases)
What you need to know:
The Dogue de Bordeaux is prone to subaortic stenosis (SAS) and dilated cardiomyopathy (DCM) — two serious heart conditions that can shorten their lifespan. According to an online health survey, about 4.7% of Dogues are diagnosed with some form of cardiac disease.
The scary part? Many dogs show no symptoms until the disease is advanced.

How to Protect Your Dogue’s Heart
- Routine heart screenings – Ask your vet for a cardiac evaluation, especially as your dog ages.
- Maintain a healthy weight – Extra pounds put unnecessary strain on the heart.
- Low-sodium diet – Consult your vet about heart-friendly nutrition.
- Avoid overexertion – Limit intense exercise, especially in hot or humid weather.
3. Hip Dysplasia: A Painful Joint Problem (25–47% Prevalence)
What you need to know:
Hip dysplasia occurs when the hip joint develops abnormally, leading to arthritis, pain, and reduced mobility. Prevalence varies by country:
- United States: ~25.5%
- France: ~32.2%
- Finland: ~47%
This condition is often inherited, but lifestyle plays a huge role in how severely it affects your dog.

How to Prevent and Manage Hip Dysplasia
- Choose a responsible breeder – Insist on OFA or PennHIP certification for both parents.
- Start joint supplements early – Glucosamine and chondroitin can support long-term joint health.
- Provide controlled exercise – Avoid high-impact activities like jumping or intense running on hard surfaces.
- Keep your dog lean – Obesity dramatically increases pressure on the hips.
4. Bloat (Gastric Dilatation-Volvulus): A Sudden, Life-Threatening Emergency
What you need to know:
Bloat occurs when the stomach fills with gas and twists on itself (volvulus). This cuts off blood flow and can kill a dog within hours — even with emergency surgery.
Because the Dogue de Bordeaux is a deep-chested breed, they are at significantly higher risk than average dogs.
Warning signs: Distended abdomen, unproductive vomiting, restlessness, drooling, pale gums.
⚠️ If you suspect bloat, get to an emergency vet immediately. This is not something to “wait and see” about.
How to Minimize Bloat Risk
- Feed smaller, more frequent meals – Two or three small meals per day instead of one large one.
- Use a slow-feeder bowl – Prevents gulping air while eating.
- No vigorous exercise after meals – Wait at least 1 hour after eating before running or playing hard.
- Consider preventive surgery – A prophylactic gastropexy (“stomach tacking”) can be done during spay/neuter to prevent stomach twisting.
5. Brachycephalic Syndrome: Breathing Problems Due to a Flat Face
What you need to know:
The Dogue de Bordeaux has a short nose and flat face — a trait called brachycephaly. While adorable, this anatomy can cause brachycephalic obstructive airway syndrome (BOAS) .
Symptoms include noisy breathing, snorting, exercise intolerance, and blue gums in severe cases (a sign of oxygen deprivation). Heat and stress make it worse.

How to Help Your Dogue Breathe Easier
- Keep them cool – Never exercise your Dogue in peak heat or humidity.
- Maintain an ideal weight – Extra fat around the throat makes breathing harder.
- Reduce stress and excitement – Panting from anxiety worsens airway issues.
- Ask your vet about surgery – In severe cases, procedures like nares resection or soft palate trimming can dramatically improve quality of life.
Summary: 5 Genetic or Disease-Related Causes of Mortality in Dogue de Bordeaux
| Cause | Key Takeaway |
|---|---|
| Cancer | Regular vet checks save lives |
| Heart Disease | Screen early, manage weight |
| Hip Dysplasia | Breed responsibly, control exercise |
| Bloat | Slow feeders + consider gastropexy |
| Brachycephalic Syndrome | Avoid heat, watch for breathing sounds |
The Dogue de Bordeaux’s 6–8 year lifespan is shorter than many breeds, but you have real power to influence their health and happiness. By understanding these five risks — and taking proactive steps — you can give your gentle giant the longest, most comfortable life possible.

What is the most common cause of death in French Mastiffs?
Cancer is the leading cause, accounting for approximately 30% of deaths — particularly lymphoma and mast cell tumors.
Are Dogue de Bordeaux prone to hip dysplasia?
Yes. Depending on the country, 25–47% of Dogues de Bordeaux are affected by hip dysplasia. The United States has a lower rate (~25.5%), while Finland has the highest reported prevalence (~47%).
How can I prevent bloat in my Dogue de Bordeaux?
You can reduce risk by:
Considering prophylactic gastropexy surgery during spay/neuter
Feeding smaller, more frequent meals
Using a slow-feeder bowl
Avoiding exercise for 1 hour after meals
Do all Dogue de Bordeaux have breathing problems?
Not all, but many experience some degree of brachycephalic syndrome due to their flat faces. Symptoms range from mild snorting to severe exercise intolerance. Keeping them lean and cool helps tremendously.
Is the Dogue de Bordeaux a healthy breed overall?
They are generally healthy for their size, but they are considered a high-risk breed for several serious conditions (cancer, heart disease, hip dysplasia, bloat). Working with a reputable breeder who performs OFA health testing is essential.
What health tests should a Dogue de Bordeaux breeder perform?
Responsible breeders should provide OFA or PennHIP for hips, cardiac evaluation for heart disease, and thyroid testing. Ask to see results before buying a puppy.
