The only thing I can suggest is to get samples of different foods to see if they like it. You can get them at pet food stores, or online from the companies.
My dogs are not picky eaters. I feed them Horizon Legacy, Horizon Amicus, Fromm Duck and Sweet Potato (not grain free, but low grain and contains no corn, wheat, or soy), and currently feeding Evangers Chicken and Sweet Potato grain free. They like them all. Evangers also has a grain free called Meat Medley, which my dogs also have eaten and like. You might also try the Fromm grain free formulas. Another food the are trying to get me to try is Nature's Logic, but I haven't tried it yet.
I'm sure others will chime in with other ideas. The best and most economical way to try foods is to get samples though.
