Have you had your dog allergy tested? It could be food allergy but it could also be a storage mite allergy. My dog has storage mite and dust mite allergy. All dry dog food has storage mites so unless you switch to wet, raw or home cooked food he may still have symptoms. Mine had the watery eyes, chronic ear infections and itching. I started cooking his food which helped tremendously. He is on apoquel too which takes care of his dust mite allergy so he stopped the constant paw licking. Also consider using a novel protein. I found after many months that my dog is also allergic to both chicken and beef, but that wasn’t obvious until I addressed his other issues. Allergy testing at least pointed me in the right direction so I could focus on the environmental allergies first and then the food allergies. Good luck!
