The protein then either flakes off on its own or comes off when that bit of hair or skin is shed. When the allergic person breathes this bit of protein their body doesn’t recognize it as dog protein, it thinks it is a germ.

It is the histamine that makes you cough and wheeze. So, you must deactivate or denature that protein. For starters, don’t let the dog lick you…in the face or anywhere else.
