I have a picky eater who also happens to be allergic to all poultry. I was hesitant to order him the beef and salmon flavor since I was told by several vets if it is not a prescription hypoallergenic food the ingredients are not guaranteed to be accurate. He has been eating hypoallergenic food for a year, but I don't like the idea of him eating the same food day in and day out.  So I ordered the beef and salmon flavor and figured I would try it. So far he's been eating it without any allergic reaction ( skin issues).  He also loves it. Hopefully this will be a reliable formula to alternate with the prescription food
