Vets say “maybe, but why take that chance”.
Vets get their training in nutrition from Purina and Hills (Science Diet) and that is why they sell their foods in their offices. Next time the vet tells someone to feed the K/D look at the ingredients? It’s pure crap. It was 15 years ago I had a dog with kidney failure and the vet tried to push k/d that sent me into learning all about animal nutrition... it as a puppy that died the day after her vaccines that made me research those, none of us are too old to learn before it’s too late.
