> “There’s really, truly no completely, 100 percent hypoallergenic dog. Even hairless dogs can make the allergen,” says John James, a spokesperson for the Asthma and Allergy Foundation of America. “It’s really a marketing term,” says David Stukus, an allergist at Nationwide Children's Hospital and a member of AAFA’s Medical Scientific Council. When I asked several allergists around the country if perplexed owners ever come in allergic to their expensive, supposedly hypoallergenic dog, their answers were unequivocal: “All the time.”

> …although breeds that shed less fur or hair are commonly considered hypoallergenic, the fur or hair itself is not what causes allergies. Rather, it is proteins present in the dander, or small flakes of skin, or saliva. All dogs make these proteins, and all dogs have skin and saliva.
