I hate to say it, but even if you bring ZP info with you to your vet clinic, it sounds like they will likely not approve of it anyway. I was scared to mention that Odie eats some ZP to the vet tech we saw, but she not only knew what it was, but has fed her dog raw before! She stopped feeding raw since because her dog had some issues but she recognized that ZP was a great food. She did suggest that I stick to Acana when I told her Odie was experiencing some diarrhea on the ZP, but I really liked her logic--the proof is in the dog. Honestly, I think that it's the same with humans and nutrition. Our governments tell us what to eat, and some (most) of the info is terrible.
