5 Common Dogues De Bordeaux Health Concerns

The Dogue de Bordeaux, sometimes called the French Mastiff, is a loyal, protective, and affectionate giant. These dogs make wonderful watchdogs but need early socialization and training to avoid becoming overly territorial. With the right care, they are loving family companions and often do exceptionally well with children.

Before welcoming one of these gentle giants into your home, it’s important to be aware of the most common Dogue de Bordeaux health concerns. Like many large breeds, they are prone to specific conditions that owners should closely monitor. Below, we’ll explore five of the most common Dogue de Bordeaux health problems and what you can do to support your dog’s well-being.

Aortic Stenosis in Dogues De Bordeaux

Heart problems are unfortunately not uncommon in the breed, and aortic stenosis is one of the biggest concerns. This condition narrows the heart’s aortic valve, forcing the heart to work harder. 

The tricky part? Most dogs show no obvious symptoms at home. Owners usually only learn about it when the vet hears a heart murmur during a routine exam, around 6 to 12 months of age.

• Mild cases are often managed through lifestyle changes, such as avoiding excessive exercise.
• Severe cases usually require long-term medications to keep the heart rate under control.

That’s why wellness visits are so important. Early detection means your pup may only need a few lifestyle adjustments, such as avoiding overexertion. 

Dilated Cardiomyopathy

Another issue to keep on your radar is dilated cardiomyopathy (DCM), a condition in which the heart muscle weakens and can’t pump blood as efficiently. Owners often notice subtle changes first—maybe their dog is more tired than usual, seems short of breath after mild activity, or develops a soft cough at night.

Because these signs can look like “just slowing down,” it’s easy to miss. Diagnosis usually involves various tests, including X-rays and ECGs, and while treatment varies, medications can help manage the condition. Dogs may be prescribed antiarrhythmic drugs, vasodilators, bronchodilators, or other medications to help cope with the associated symptoms.

Bloat in French Mastiff

If there’s one health concern every large-dog owner should know about, it’s bloat. Also known as gastric torsion, this occurs when the stomach fills with gas and twists upon itself. It can be fatal if not treated immediately.

Signs of bloat in a Dogue de Bordeaux often include: 

• Distended or swollen stomach
• Restlessness or pacing
• Retching without bringing anything up
• Excessive drooling or salivation

Owners sometimes describe it as their dog “trying to throw up, but nothing comes out.” If you ever see these signs, don’t wait—head straight to the emergency vet.

Prevention isn’t foolproof, but feeding smaller meals, slowing down fast eaters with puzzle bowls, and avoiding strenuous exercise right after eating can reduce risk.

Hip Dysplasia: A Common Large-Breed Struggle

Big dogs often struggle with joint problems, and for the Dogue de Bordeaux, hip dysplasia is at the top of the list. This happens when the hip joint doesn’t fit quite right, leading to pain and stiffness over time. Owners might first notice their pup hesitating on stairs, limping after play, or being less eager to jump up on the couch.

Because hip dysplasia is mainly genetic, it can’t always be prevented. However, weight management, proper exercise, and joint supplements can make a world of difference. In severe cases, surgery may be an option.

This is also where new developments in regenerative medicine may hold promise. At Gallant, we’re actively researching how stem cell therapies may help support dogs with joint conditions like osteoarthritis. These therapies are designed to work with the body’s own cells to reduce inflammation and encourage tissue repair.

Lymphoma in Dogues De Bordeaux

Finally, the Dogue de Bordeaux is also at risk for lymphoma, a cancer of the lymphatic system. It’s often detected when owners notice an unusual lump, which turns out to be an enlarged lymph node. Other symptoms may include weight loss, lethargy, or decreased appetite.

While lymphoma is not curable, chemotherapy is the most common treatment and may improve quality of life and extend survival.

As a preventative step, it’s worth asking your breeder about family history, since genetics may play a role. 

Living with a Dogue de Bordeaux

Every breed has its challenges, and the Dogue de Bordeaux is no exception. Conditions like aortic stenosis, DCM, bloat, hip dysplasia, and lymphoma can sound overwhelming, but knowledge is your best tool. With awareness, preventive care, and regular check-ups, you can help your gentle giant live a long, fulfilling life.

These dogs return every ounce of care with love, loyalty, and devotion—making them well worth the effort.
