Quick answer
Mitral Valve Disease (MVD) is a high-severity condition documented in the American Water Spaniel. It has a hereditary component, so ask breeders for health-screening documentation. Estimated treatment cost is £1,500-£5,000/year.
Mitral Valve Disease (MVD) is one of the most frequently diagnosed conditions in the breed within the American Water Spaniel. Common indicators include heart murmur detected on examination, coughing especially at night, and exercise intolerance. MVD is the most common heart disease in dogs, characterised by progressive degeneration of the mitral valve leaflets causing regurgitation of blood back into the left atrium. It leads to cardiac enlargement and eventually congestive heart failure. It typically becomes apparent at 5-10 years. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £1,500-£5,000/year, making comprehensive pet insurance a practical consideration.
If your American Water Spaniel is showing any of these signs, consult your veterinarian promptly.
The EPIC and PROTECT trials established that Pimobendan delays onset of heart failure in preclinical stages. Once failure develops, diuretics, ACE inhibitors, and Pimobendan are combined.
