Science now tells us there's close to a 1 in 3 chance you're 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.

If you are, then there's a possibility you might not be allergic to female dogs, as well as some male dogs, especially if they were neutered at a young age.

When male dogs get snipped as puppies, their prostate gland doesn't fully develop.  So they can't produce the protein you're allergic to.
