Allergic to dog? I get these small hives after touching my dog. Will allergy medicine treat this?

This is not the sort of question to ask strangers. You should seek professional advice. Go to google.com and type "allergic to dog" and consider the links you get from qualified people. For instance it's hard to tell if you are allergic to the dog or to something in the grass where the dog plays. Since it's so cheap to test, try getting a wash and trim from a professional groomer, and ask about your reactions while you are there. Check with a vet before you pay for allergy tests for yourself.
