I don't personally like Iams at ALL
I'm glad you're researching and taking the time to find a new food!
I personally prefer grain-free, higher-ish protein, low card dog kibbles. My favorite (or Jackson's favorite) by far is Orijen and Acana (both made by Champion Pet Foods). Really great foods!
I also like Fromm, Go! Endurance, Nature's Variety Instinct, Wellness CORE, etc.
Remember when you switch to do it slowly. I believe it's 75% of old food, 25% of new food to start with, then gradually switch 100% over. When switching from a food like Iams to a high quality food, sometimes it can take their tummies a bit to adjust. Also remember not to over-feed! With higher quality foods, you often feed a lot less.
