Understanding Heart Health in the Wire Fox Terrier

Quick answer

The Wire Fox Terrier has a recognised tendency toward Myxomatous Mitral Valve Disease. While this is a common concern in the breed, proactive monitoring of your dog's breathing, energy levels, and gum color allows you to detect changes early. Regular checkups with your veterinarian ensure that any necessary management begins as soon as a heart murmur or other clinical sign is identified.

Myxomatous Mitral Valve Disease

Myxomatous Mitral Valve Disease is a recognised tendency in the Wire Fox Terrier. This condition involves the heart valves, which normally act as one-way doors to keep blood flowing in the correct direction. When these valves begin to degenerate, they may fail to close tightly, allowing blood to leak backward into the heart chamber. Over time, this places extra strain on the heart muscle.

At home, you may not notice anything during the early stages of the disease. As the condition progresses, you might observe your dog tiring more easily during walks or showing less interest in play. Because this is a recognised tendency rather than a proven one, regular physical examinations are essential. Your veterinarian will listen to your dog's chest with a stethoscope to detect a heart murmur, which is often the first clinical sign of valve changes. If a murmur is detected, your vet may recommend an echocardiogram, which is an ultrasound of the heart, to visualize the valves and assess the severity of the condition.
