Hi all. Just trying to find some positives after hearing from the vet that my 9 year old border collie has a heart murmur grade 3. He was being examined for a stomach issue but while there the vet noticed it. I know Google is always a worst case scenario, so I'm hoping someone can give some better news of their own experience. I realise it's not good news of course but I am feeling really quite upset by it all. Thanks.
