I used Dr. Schulze's Heart formula liquid, dosing three times a day, along with large doses of coQ10 and other supplements for my dog that was diagnosed February of 2022. I did that Heart formula for about a solid month, but do still give her a capsule of Now cayenne daily. (She had been prescribed the Furosemide and Enalapril but I stopped after a couple of days because it made her like a zombie.) She'll be 16 years old in November. The Vet had said she'd be dead in several months of her diagnosis, but now said she won't be dying from it.
