i am new to this forum. My cavalier Grace has had a murmur for a couple of years but was recently dx with CHF. We have gone throu a month and a half of vet and specialist visits and medication adjustments. She was given enalapril and furosemide and then added to spironolactone. These could not keep away fluid buildup and yesterday she was put on vetmedin. Today she is showing much imProvement. I am hoping this will keep her stable for some time. Has anyone had a similar experience or any advice? VHF came on quickly and seemed to be resistant to diuretics and ace inhibitor alone. I worry this means she doesn't have much time left.
