im no expert but we originally started our first boxer on iams and it was a no go, we finally got him on a grain free food and now both are on it and they are doing wonderful. its a quality food that matters. not to be rude but iams is not a good quality food. you can google food reviews and it will come up with all sorts of information and i am sure there are many threads on this site about food. also raw feeding is an option, we have not gone there bc my fiance is not a fan but he is not informed but we use Earthborn Holistic grain free meadowfeast.
