Not to put a damper on the Obama family’s canine quest, but allergists have a news flash: There’s no such thing as a hypoallergenic dog.

      More women opting for preventive mastectomy - but should they be?

      Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

Doctors who specialize in children’s allergies say kids who are truly allergic to dogs probably shouldn’t get one.

So Malia and Sasha, how about a fish instead?

President-elect Barack Obama has said his young daughters have been promised a dog with their move to the White House. And in his first post-election news conference last week, he announced that Malia “is allergic, so it has to be hypoallergenic.”

It’s a common misconception. In response, the American Academy of Allergy, Asthma & Immunology issued a statement Wednesday saying, “There is no truly ’hypoallergenic’ dog.”

Another misconception is “that people are allergic to a dog’s hair, and it is falsely believed that a dog that sheds less will not cause a reaction,” the academy said.

Obama’s transition team declined to comment.

Breed makes little difference
While some people with dog allergies say some breeds cause them more problems than others, there isn’t any scientific proof to back that up, said the academy’s Dr. Clifford Bassett, a New York City allergy specialist. All dogs produce proteins that can cause allergies. These proteins are found in dogs’ dander — which is dead skin cells, not fur — and saliva and urine, explained Dr. Elizabeth Matsui, a children’s allergy expert at Johns Hopkins Children’s Center.

Learn how allergic reactions occurGrooming and bathing can remove much of the dander and cause fewer allergic symptoms, and some breeds tend to be groomed and bathed more often. But it’s that treatment rather than the breed that makes the difference, doctors say.

People with general allergies but not a specific allergy to dogs will probably do fine with a dog, said Dr. Robert Naclerio, a University of Chicago allergy specialist.

But for those with a true dog allergy, diagnosed by a skin test, “then I wouldn’t recommend bringing it in,” he said, “because you are going to have symptoms.”

Those include a runny nose, teary eyes, sneezing and coughing.

Naclerio said people with pet allergies can “outgrow” them, though it takes years.

That said, the allergy academy offers tips for minimizing the problem. (White House cleaning staff, take note):

  • Clean the house often with vacuums equipped with special filters and double bags.
  • Keep the dog out of the allergic child’s bedroom.
  • Remove carpeting, where dander also can build up.
  • Bathe the animal weekly.
