Many people these days, our nation's president included, are interested in having a hypoallergenic dog. That is, a dog that supposedly will cause less allergy problems for an allergic person.

It sounds great - many of us have suffered from allergies our whole life. And many of us love dogs.

But unfortunately, that's about where the good news stops.

A recent test from the Henry Ford Hospital has shown that there is basically no difference between purebred or mixed breed hypoallergenic dogs, and non-hypoallergenic dogs. Almost all of them tested positive for levels of Canis Familiaris 1, which is the protein that causes most people to have an allergic reaction.

So, don't go out and spend a fortune on that "Portuguese Water Dog" - he's not going to help the allergies.
