Mary, I'm sorry to hear this. Hopefully Specs has only a very mild one and won't require any medication for it. I'll keep him in my thoughts and prayers.

I recently learned that both Sunny and Sky have heart murmurs. Sunny will be 8 in late August and Sky just turned 6 in June. Sunny had his annual exam in April and was fine. He was later having some behavioral issues so I brought him to my holistic vet and she noticed that he had a heart murmur. He's now on a calming herbal pill which is also good for his heart. She checked him out again and said that it's very slight and that he has a very strong heart so
both my regular vet and she don't think that I need to do anything more at this time.

When Sky had his annual exam in June,my regular vet noticed that he had a
slight heart murmur and he had been seeing my holistic vet several times and she never noticed one. He then had another appointment with my holistic vet and she also noticed that he had one but it's also very minor so at this time I don't have to anything more about it.

Many years ago one of my doctor's noticed that I had a slight heart murmur and she did some tests but everything was normal. Since then no other doctor has ever detected a heart murmur on me. My dad has one and all he has to do is to be sure to take some pills before and after he goes to the dentist.
