We use only oatmeal shampoo and put a vet salve on her hot spots. Her ears get irritated & infected and our vet says she's the worst allergy case he's ever seen. She can only have venison. She gets Natural Balance Venison & sweet potato since potato is low on her allergy chart plus canned pure venison. I don't know what else we can do to keep her comfortable. She's had shots, takes benidryl and had skin tests. ??????????
