I have a dog with horrible allergies, inhaled and food. My problem was with performance foods, they are mostly chicken based, not usally a good choice with food allergies.After many, many foods, I have found eukanuba k/o ( kangaroo and oats) is a really good food, at least for my guy. Try looking at this sight it gives all the info on almost any dog food out there. www.doberdogs.com. Good Luck, it's not easy to find the right food.
