My 8 year old Bentley has just been diagnosed with a grade 3 murmur. I'm just devastated and so sad. He also has symptoms of Cushings, altho no actual diagnosis yet (he has all the symtoms however, as well as a nasty skin infection, on meds for the skin issue), we will be going back to the vet for tests.

Can anyone provide me with some good advice/information for treatment/supportive care for a heart murmur? Does Lasix (furosemide) help at all?
