There are 6 'grades' of heart murmurs. they are expressed as 1/6, up to 6/6 the worse. Most dogs just cough from the condition, but as it progresses they can start to retain fluid in their abdomens, along with other symptoms.
Emmie's blood tests came back, and the vet told me about them. good news! The really high 'inflammation' test CK came way down. Liver functions the same or better. The only thing she wants to recheck is a blood sugar that was low. She thinks it is an error from the blood sitting too long before being 'spun down' to separate the blood from the serum. I am to take her in thursday for another test to make sure.
