Quite frankly, I don’t.
I’ve had vets (whom I found to be otherwise perfectly competent) preach about Purina Dog Chow and Royal Canin which, based on the ingredient list, can range from mediocre to pure junk food filler. Their claims that “these companies have been around for decades and employ lots of scientists and who run lots of studies” doesn’t mean a thing to me. I read enough and have seen firsthand what quality nutrition looks like in canines to know that they’re either pushing a product that they carry or their student loans were financed by one of the big manufacturers.
My current vet does carry some condition related food but by and large, they tend to stay out of that part of the business. I’m lucky in that I have a dear friend who is a vet tech at the office who can tell me the difference between what is clinically necessary and what is a sales pitch.
