I have a lap puppy, a chihuahua, she was terrified of lighters and when smoking she would dart from my lap any time I reached for my lighter, slowly she would ease her way back but would always sneeze and run away again when the smoke rolled. Since I started vaping, she never gets off my lap, and actually sticks her nose up in the air to try to smell the vapors. I usually have two different juices going at the same time, so her interest is always intrigued. My larger German Shepherd is also curious and constantly wants to sniff the PV's.
