Dog Allerigies? 30% of People are Only Allergic to Male Dogs

I know so many dog lovers that suffer from dog allergies. Good news! Research says about 30% of those people are actually only allergic to male dogs!

An allergist at one of Harvard's teaching hospitals in Boston says about 30% of people with dog allergies are really just allergic to one specific protein made in the prostate of male dogs.

The protein is called "Can f 5." And there's a test now to see if you're sensitive to it.
