I currently feed my chihuahuas Natures Variety Instinct. It's a great food for my two, but I just moved and I can't get it where I live now. I used to feed Wellness, and have decided to go back, but don't know what to try. I originally put them on grainless because my girl, Venus, is allergic to corn, but I'm starting to wonder if they really need a grainless food. I know Core is good, I've tried it before, but I'm really considering their Super5Mix Small Breed. They're not highly active dogs, but not lazy either. I just don't know if they're really benefiting from a high protein diet either, if they really don't need it. Does anyone have any input either way?
