I have five dogs and the two with the best noses just sniff the air and relax. The two with the worst noses are OK most of the time unless I give off a big thick cloud in which case they back away slowly. One dog, Oliver, tries to eat the vapor as fast as he can snap his jaws. And that's not the most fun you can have while vaping. No sir, snapping dog jaws out of thin air close to your mouth. -Magnus
