Understanding Heart Health in the Dogue de Bordeaux

Quick answer

The Dogue de Bordeaux has a recognised tendency toward a heart condition known as Subaortic Stenosis. While this is a recognised tendency rather than a proven one, it is important for owners to monitor their dog for changes in energy levels, breathing patterns, and gum color. Early detection through routine veterinary examinations is the best way to manage your dog's long-term health.

Subaortic Stenosis

Subaortic Stenosis is a heart condition that involves the narrowing of the area below the aortic valve. In the Dogue de Bordeaux, this is a recognised tendency rather than a proven one. The condition often presents with abnormal tissue proliferation and hypoplasia of the aortic annulus and root. Because this condition affects how blood flows from the heart to the rest of the body, it can place additional strain on the heart muscle over time.

At home, you may notice your dog tiring more easily than usual during exercise or appearing lethargic. You might also observe your dog struggling to catch their breath or panting excessively when they have not been active. A veterinarian will typically listen for a heart murmur during a physical examination. If a murmur is detected, the vet will likely recommend an echocardiogram, which is an ultrasound of the heart, to visualize the structure of the aortic valve and the surrounding tissue. This test is the gold standard for confirming the presence and severity of the condition.

Maintaining a Healthy Baseline

Because heart conditions can develop gradually, the most effective tool an owner has is a solid understanding of what is normal for their specific dog. The common mistake many owners make is waiting until a dog shows obvious signs of distress before seeking help. By the time a dog is visibly struggling, the condition may be quite advanced. Instead, focus on daily observations that allow you to spot subtle changes early.

Body Condition Score

Maintaining an ideal weight is vital for heart health. Excess weight forces the heart to work harder to circulate blood throughout the body. You should be able to feel your dog's ribs easily without a thick layer of fat covering them. If you are unsure about your dog's weight, ask your vet to show you how to assess their body condition score.

Gum Color

Healthy gums should be a vibrant pink. If you notice the gums becoming pale, white, or a bluish-grey color, this indicates that the tissues are not receiving enough oxygenated blood. This is a significant finding that warrants a prompt visit to the clinic.

Breathing at Rest

One of the most reliable indicators of heart health is the resting respiratory rate. When your dog is sound asleep, count how many times their chest rises and falls in one minute. Most dogs should have a resting rate below a certain threshold. If you notice this number consistently climbing over several days or weeks, it is time to have your dog evaluated.

Mobility and Behavior

Changes in mobility are often overlooked as simple signs of aging, but they can be linked to heart function. If your dog suddenly stops wanting to climb stairs or lags behind on walks, consider whether this could be related to fatigue. Similarly, keep an eye on their behavior. A dog that is usually eager to greet you at the door but suddenly seems uninterested or lethargic may be signaling that they are not feeling well.
