Not ALL vets recieve kickbacks from any of the food companies. We carry several name brands including Purina, and Royal Canin in addition to the Hills. Our hospital only sells prescription diets, not regular foods. Head vet says he's running a vet hospital not a pet food store. To my knowledge, and the lady that does the ordering, the hospital recieves no incentives or kickbacks from any of the sales of the prescription foods.

I do agree with the statement; feed whatever works best for your pet. No one food does great for every single animal. I've seen dogs get horrible diarrhea and vomiting from Canidia (sp?) and do great on plan old Purina dog/cat chow.

If the dog is doing fine on Hills then leave well enough alone. If there's a problem, only then consider switching. Hills is not a bad food by itself, just some animals do good on it, some don't.
