There is some evidence that feeding grain-free exclusively can lead to cardiac issues with some dogs. My own vet has had several clients that apparently experienced this. At her urging, I switched from TOTW to Purina Pro Plan. My younger dog is on a ProPlan weight management kibble and my senior dog is on Proplan Senior. I tried Victor, but it is performance kibble (at least the one I got) and way too rich for my two dogs.
TOTW has a grain inclusive variety which I've bought at Petco, though I'm sure it's available elsewhere.
BTW, that same vet advises against All Life Stages food. She insists there isn't a single kibble that's equally appropriate for puppies, adult dogs and seniors. Your vet may have different opinions and some here will say that a vet isn't an expert on canine nutrition.
