Mitral Valve Disease & Heart Murmurs in Dogs
Mitral Valve Disease (MVD) is the most common cause of heart murmurs in dogs, particularly in older and small-breed dogs. While hearing the words “heart murmur” can be concerning, not every dog progresses at the same rate, and many continue to enjoy a good quality of life for years with appropriate monitoring and veterinary care.
In this series, we explored:
• What the mitral valve does
• How Mitral Valve Disease develops
• Why murmurs occur
• Common signs to watch for
• Diagnostic testing used to assess heart function
• The importance of ongoing monitoring
Understanding the condition is the first step toward making informed decisions about your dog’s health and wellbeing.
