My Westie has bad allergies and the benadryl did not help him either. Zyrtech seemed to help him better; along with a soothing cortisone shampoo that my Vet prescribed. If things are really bad; we go with a step-down dose of prednisone - but we don't often have to go there.
I hope that you can find the cause of these problems.
