There’s really no such thing as a hypoallergenic dog. So-called hypoallergenic dogs don't shed or shed very little. A dog with a hairless, low-shedding or non-shedding coat passes on less dander. If there’s less fur, then there’s less dander. And it’s protein in the dander from the skin that causes allergic reactions, not the fur. But, according to scientists, you can’t breed away the protein in dogs that causes allergic reactions. And so ... hypoallergenic dogs do not exist.
