Write a reviewHeartRx™ contains pimobendan, a clinically proven medication used to support dogs with heart disease, especially those with congestive heart failure (CHF) caused by mitral valve disease (MVD) or dilated cardiomyopathy (DCM).
About HeartRx
Pimobendan works by improving the strength of heart muscle contractions while also widening blood vessels, helping the heart pump more efficiently and reducing strain on the cardiovascular system. This dual action helps improve circulation, slow disease progression, and support a better quality of life for dogs with heart conditions.
When used under veterinary guidance, HeartRx™ plays an important role in long-term cardiac management and supportive care for affected dogs.
