It depends on if the allergy is food, or environmentally related. I had one that had seasonal allergies. The only good thing is I have the same allergies. So as soon as I would start to get stuffy, I would start her on Zyrtec. Before I knew this, we would be at the dermatologist to get it under control.
You could always give Benadryl to help with the itching, and bathe with a gentle shampoo. I like MiconaHex+Triz shampoo, because it’s anti microbial and moisturizing. You can also rub some coconut oil in your hands, and then rub on the areas that are the most inflamed. None of the things are going to get rid of the allergy. Just helps keep him comfortable until you get to the vet.
