I can't believe that someone is serious about thier breath scent. Deer don't know or care what your breath smells like. they won't know what it was if they smelled it. If your that worried about them smelling you, you had better just stay home because they can smell you anyway and I don't care what you do or how hard you try to cover up, they still smell you before the truck door slams. plus they can tell you what brand of scent blocking gum you are chewing..
