Max (15weeks old) has a heart murmur that the vet says could be grade 3 or 4. The vet wants to do an ekg and echo to diagnose. Is this worth the money? Is there anything I can do to help my puppy if there is something wrong with his heart?? He plays well, very active, eats, and drinks plenty of water. I'm super worried about him. All advice/help is much apprecaited.
