In truth, no dog is completely hypoallergenic. All dogs produce dander (microscopic skin flakes that can be inhaled and potentially irritate the nose and eyes or cause sneezing) and of course saliva. Dander and saliva are the main causes of allergic reactions in some people. However, because the breeds in this list are low shedding it's thought they may also produce less dander and are better for people with allergies to dander. If you have allergies you should spend some time around the breed you are considering, before you buy, to see if the breed causes you to have an allergic reaction.
