My dog has pea, oatmeal, n sweet potato allergy. I tested it with (DNA allergy tested kit). We’ve been pretty lucky with natural balance potato n duck formula and lamb meal n brown rice formula. Both has no three ingredients that my dog allergic to. Also, purina beyond (if u dont mind purina) simply 9 the chicken barley or lamb barley has none of those 3 ingredients that my dog allergic to as well. So hope this help. I know how hard it is to find food for dog that allergic to thos le ‘good’ ingredients. But it is what it is. Good luck!
