Heart Health and the Dachshund

Quick answer

Dachshunds are known to have a recognised tendency toward specific heart valve issues, particularly those affecting the mitral valve. While these conditions can be serious, proactive monitoring of your dog's breathing, energy levels, and gum color at home allows you to catch changes early. By maintaining a consistent health journal and working closely with your vet on regular auscultation and imaging, you can manage these concerns effectively.

Myxomatous Mitral Valve Disease

This is a recognised tendency in the breed. Myxomatous Mitral Valve Disease involves the degeneration of the valve that separates the left atrium from the left ventricle. Over time, this valve may fail to close tightly, leading to blood flowing backward into the atrium. Male Dachshunds are noted for a specific vulnerability where this process can lead to atrial wall rupture. This is a recognised tendency rather than a proven one, but it requires diligent observation by owners of male dogs.

At home, you might first notice your dog becoming tired more quickly during walks or showing a reluctance to climb stairs. Some owners notice a soft cough, particularly at night or when the dog is resting. Your vet will use a stethoscope to listen for a heart murmur, which is often the first clinical sign of this condition. An echocardiogram, or heart ultrasound, is the standard test used to confirm the diagnosis and assess the severity of the valve leakage.

Mitral Valve Dysplasia

Mitral Valve Dysplasia is a recognised tendency in the breed. Unlike degenerative disease, dysplasia refers to a malformation of the valve structure that is present from a young age. This condition can also cause blood to flow in the wrong direction, putting extra pressure on the heart chambers. How this passes down is not settled, but it remains a known consideration for Dachshund owners.

Owners may notice that a young or middle-aged Dachshund seems to lack the stamina of their peers. Because the heart is working harder than it should, the dog may appear lethargic or exhibit rapid, shallow breathing even when not exerting themselves. A veterinarian will investigate this by listening for heart murmurs and often recommending an echocardiogram to visualize the structure of the valve. If the dysplasia is significant, the heart may show signs of enlargement, which the vet will track over time.
