Can you Combine benadryl and Chlorpheniramine for dog allergies?

Most medications you cannot mix, ask your doctor for best answer dude :P me, I'm more of the answering how to get a buzz sorta thing xD but this can really mess your system up because benadryl as diphenahydramine in it, about 25mgs most prescription ones are anywhere from 25-50 at most because 75-100 can kill your liver, (if taken often) so its given only when having sever allergic attacks or bronchial issues due to Allergies, but i really recommend asking a doctor not the internet :P
