A new study found that while hypoallergenic dogs are believed to produce less dander and saliva and shed less fur, they're just as likely to aggravate allergies as other dogs. "We found no scientific basis to the claim hypoallergenic dogs have less allergen," said lead author Dr. Christine Cole Johnson, chair of Henry Ford's Department of Public Health Sciences. Researchers say the best way to prevent kids from developing a dog allergy is to expose them to dogs earlier in life. Johnson adds, "The idea that you can buy a certain breed of dog and think it will cause less allergy problems for a person already dog-allergic is not borne out by our study."

Your move, Obamas.
