According to the Achoo! blog:
"Michelle and Barack Obama's daughter Malia suffers from asthma, and they do everything they can to keep their house dust-free and dander-free.
When the Obama family decided to enter the Presidential race, they made a deal that their daughters could get a dog. After some research, the parents opted for a hypoallergenic dog - a soft-coated, Wheaten terrier - that does not trigger Malia's asthma."
Update 2013: They actually received as a gift a Portuguese water hound. Also, as he signed the "epineprine in school" act, Barack Obama announced that Malia has peanut allergy.

wheezemdPlease STOP! There is no such thing as a hypoallergenic dog. I don't know where our President is getting his advise on allergy.
wheezemdSee this 1997 NYT article. It is still valid today on hypoallergenic dogs. http://is.gd/s54w
wheezemdThe bottomline is that each dog, not breed, may produce different levels of allergen. Who knows Bo's level.
