If it were me, I'd leave the puppy on this food for the first couple of weeks you have it home. Then, I'd be looking to try a kibble that has it primary protein coming from named meat sources. With IAMS Smart Puppy: once the moisture is cooked out of the chicken (#1 ingredient) it makes the #2 listed ingredient of cornmeal the first ingredient by weight. Meat proteins are more highly digestible than corn protein. Once you do some researching, you'll find there are quite a few reasonably priced brands to try.
