Hi Elaine. Welcome to you and Lucy. I sure there will be many responses with experiences soon. I have not had a dog with MVD at this point...knock on wood as I have 5 cavaliers but I am a nurse. In people with heart disease we do a lot of the same things that they are doing with the cavaliers. Furosemide or Lasix as it is more commonly called to decrease the fluid overload...there are other diuretics when this one is no longer effective at least in humans. Then the other meds to help the heart beat more efficiently and to decrease the workload on the heart. The one thing that people can utilize that would help greatly but would not be possible in dogs is oxygen. My best guess is Lucy is not in pain. What I see ( in humans) is fatigue. If your heart does not work well then everything you do takes more effort.
I hope Lucy's meds are helpful and her condition stabilizes for a long time.
