This sounds like a good plan Joanne.
Maybe the vet will have some answers for you.
If you find a brand that works, it might be good to check into other similar brands and keep a stock of that bland diet in the freezer if possible because dog food companies seem to like changing and screwing with formulas, and if this happens it’s nice to have an immediate back up until you come up with a solid long term plan.
(I had a friend years ago feed California Natural for his Bulldogs ear and skin issues, his dog was doing SO well and when the company went kaput, he was so upset.)
