It depends. Some dogs with appropriately managed congestive heart failure can live for years. Other dogs may only live days. Lasix is good for removing fluid from the lungs, but it is rarely used alone in treatment of congestive heart failure. Medications like enalapril and Vetmedin are commonly used alongside Lasix. I would recommend discussing these additional medications with your vet. https://www.petcoach.co/dog/condition/congestive-heart-failure/
