Thanks, cowlovr9797. I didn't realize they are! I haven't given up my pets yet. My son is on medications and we have hepa filters throughout the house. I've asked my big doggies to live outside for now on (they're the hairiest). I'm going to try everything under the sun before I give up my beloved animals. It's good to know that there's a doggy out there that is practically hypoallergenic just in case.
