Been researching this for a couple of days now…… finally narrowed it down to Nature’s Variety Limited Ingredient (single protein source) OR Zignature (single protein source, going to go w/ the Duck). Neither one of these has potato in it and in all the reading I have done if your dog has allergies you must stay away from potato.

One of the employees at the pet food store recommended Merrick Limited Ingredient, Duck, and Izzie loved it BUT then I found the information about the potato so returned it.
