Can you give benadryl to your dog while using hydrocortisone cream?

I have heard mixed things from vets about giving Benadryl to canines. From what I have been told, a lot of it has to do with the size of your dog. Their systems are totally different than ours, so dosing per weight would not be the same either. It really is best to go to the vet and find out what is causing the problem. They may even be able to hook you up with meds that will work better on your dogs symptoms than anything you may able to self medicate him/her with.
