If you are willing to cook for him, try going to dogaware dot com. They have some recipes for homemade food. Just substitute any foods he can’t have.

When I had an idea what my dog was reacting to, I went to chewy dot com and looked at the ingredient lists for every food they sell and made a list of possibles for my dog. It took a few hours to complete my list. Then I ordered small bags of a few different ones to try. So far I have 20 foods that he can have. Some I won’t feed because of quality control issues with the company or other reasons, but I know which foods he can eat in a pinch.
Good luck in your hunt for the right foods for your dog.
