It's not to fool the dog, it's about fooling the cop. Hide it very well in with some hamburger meat or mcdonalds scraps! The dog goes for it and the cop thinks he's just going for the food. I've heard the coffee container one doesn't work. Also, if you put it in a air tight cooler and DO NOT open it, it will keep the scent in and away from a cop/dog. Just hope the cop doesn't open it. The Spike TV show Manswers is great for these questions! It would also be smart to clean the bowl so it doesn't have any resin and it's just a 'tobacco pipe' not paraphenellia. Good luck! :thumbsup:
