Hi my name is Julie and I have a raw fed 10 year old English Springer Spaniel that has awful environmental allergies. He is Itchy itchy itchy with gooey eyes and ears. Ugh! The allergies are sort of seasonal but really year round. I have not found anything that really helps him for any significant amount of time. I want to try an OTC anti histamine. Benedryl 25 mg was not helpful. Has anyone used other OTC medicine with any success?
