My only recommendation is stay away from anything with dyes in it, particularly reds, yellows and greens. I've seen SOOO many animals come in at work with awful allergies, ear infections, and skin problems that get traced back to the dyes in the foods.

Dyes are there to look good to humans so we'll buy it. Pets don't really look in their bowls and go 'oh wow reds and greens, this must be good'. LOL
