I just got back from Petco to purchase new food for Carter.  He was always fed Science Diet's Nature's Best and I've been wanting to switch to something with more protein and less corn.
 
I was all set to purchase Nature's Balance which is one of the recommended brands from the Whole Dog Journal's list.  In talking with the girl working at Petco, I decided to look at the Nutro Max to compare with the Nature's Balance.  (I had heard many people in this forum speaking well of NM)  It still had corn products in it so I looked at the Nutra Natural Choice Ultra Puppy and decided to purchase it.  It has no corn products at all! 
I opened the bag in the car and Carter was ready to attack!  He has never taken such an interest in his Science Diet as what he did with the Nutro Ultra!  I'm hoping it will agree with his belly . . . we'll be making the switch for the next 5 days. 
Here's the website if you'd like to check it out.
