Degenerative Mitral Valve Disease
Degenerative Mitral Valve Disease (DMVD) is a common age-related heart condition in small breeds, characterized by degeneration of the mitral valve leading to heart murmur and potential heart failure.
Detailed Description
DMVD involves thickening and deformity of the mitral valve, causing blood to leak backward into the left atrium. Over time, this can lead to congestive heart failure. It is most common in older small breed dogs and can be managed with medication.
Common Symptoms
- Heart murmur
- Coughing
- Exercise intolerance
- Labored breathing
