My youngest son and I, both have allergies, mine are environmental allergies, my son's is to animals, but he has not have any problems with Max, at first I kept Max from my son's room, or his bed, he would wash his hands after playing with Max, but little by little we realized that he was fine, besides, who is going to get a boy to wash his hands that often?
One thing thou, he (Max) gets a bath every week, and we vacuum everyday, not only helps with the allergies, but with the fleas as well.
