What Should I Do If I’m Allergic to Pet Hairballs?

The best allergy defense is to avoid them. However, if you can’t move far from your allergy or, more particularly, if you can’t stand giving up your dog, cat, or gerbil,  and your symptoms aren’t relieved by over-the-counter drugs, consult an allergist. A custom-made allergen medication can be produced to acclimatize you to the four-legged allergen companions for some patients.
