Er… no, you won’t trip any chem sniffers with your pheros. I just travelled with a bunch of mine in my purse. My purse was pulled for hand inspection and the tech ran a chemical reactive strip over everything and nothing twigged. As far as the dogs, I don’t think they will hump you, and they are trained to show a positive sign only in the presence of explosives and drugs, so I wouldn’t worry.
