A. For itchy older dogs that have never had allergies in the past I would be concerned that there could be underlying illness causing his skin issues. Yes Bendaryl can be tried at the recommended dose of 1mg/lb; however it may not solve the issue.
If your pet's itching does not improve within 24 hrs of Benadryl and there are obvious crusts/scales/redness of the skin, then I highly recommend you take him into your vet for further testing of his skin and possible bloodwork to look for underlying issues or causes here that would need to be addressed if we are going to have any success dealing with his skin.
