Suspect that is wishful thinking. I thought I developed allergies to tree nuts after I ate a box of pecan cookies but probably what happened is that I finally recognized the reaction. My first dog was itchy her whole life mostly because of fleas but when I started cooking for her the mild anal sac issues mostly stopped. Itching did not. Anal sac irritation can be due to allergy. Her itching did get worse as she aged and after going through the usual antihistamines one by one for weeks at a time ended up putting her on as low a dose of steroids as I could.
Of course it could still be environmental allergies. Molds, mites and so on. Those are present year round. I'm sure you have already thought about cleansers, detergents and all that? I hope it is food allergy, that is much easier to deal with!
