Has this been proven..........?

When we talk about stuff that border on super-natural proven is hard. You either believe or don't believe. For me I believe dogs do have that ability as I saw that in my own army camp while doing night guard prowling duty many many years ago. Theirs is not really barking it sounds different at a direction me and buddy look see nothing just darkness but we feel some strange cold-ness and very fragrant flower smell.
