A friend’s golden lost his life to a cardiac event after several years on a grain free diet, confirmed by necropsy that he had a heart attack. The problem with grain-free diets is the substitution of legumes as fillers – this seems to be the contributing factor for dietary DCM. Did you have a necropsy done to verify it was the heart?

I’m so very sorry. Assuming your dog had dietary DCM, DCM is the absolute worst. We lost our Doberman in the same way, to sudden death, but in her case it’s endemic in the breed and she was diagnosed a little over a year prior. If it’s any consolation, the arrhythmic form of DCM – also called sudden death – does not allow the dog to suffer. It’s over like someone flipped a light switch. I know that’s the form I preferred for my dog – it SUCKED for us, but it was an easy departure for her, and that’s what matters most.

I would start researching raw, if you have a dog in need of a very restrictive diet that cannot easily be satisfied by mass produced options. Do a L O T of research into raw, as it’s more complicated than feeding a kibble diet.
