Q. I am fostering a 4 yo Chihuaha and he has recently been diagnosed with a heart murmur graded 5 of 6. What treatment do you recomend? Is it fatal?
A. It depends if the dog is in heart failure or not. There is no clear benefit of treating dog with heart murmur which is not in heart failure yet. Pimobendan is one of the medications which may be helpful. If the dog is already in heart failure which means he has fluid build up in his lungs then there is a list of medications that should be used e.g. furusemide, ACE inhibitor, Pimobendan, Spironolactone
