On the weekend I had experience with a friendly labrador up close at a Sydney rave.
I will give you a tiop on how to beat sniffer dogs: You won't. You show no fear and make sure the drugs are well hidden, and you wish that you are not one of the randomly or selectively chosen based on either numbers (one in every 50 picked up or whatever) and do not show any fear towards the dog or the dog handler.
I had 3 known MDMA tablets that do not contain speed, and when you smell them in a bag in any quantity, there is no smell at all. I also had a capsule of 2C-B (which i lost with my wallet later on unfortunately). This is how I packaged them. I did it all a couple of days before the rave to avoid any contact with my fingers. But I also used glad wrap over my hands the whole time out of paranoia and over-carefullness. I placed the pills side by side in their own little CLEAN baggie, de-aired it, then seal;ed it tigghly, I did the same with the capsule, but gave it it's own baggie (all baggies used were brand new and clean). De-aired the baggie and sealed, rolled up both baggies and placed them inside a bigger baggie, de-aired it then sealed tightly, I placed that baggie inside yet another baggie, same process. Then I went crazy with the glad wrap, wrapped around it abnout four or more times, which i taped closed, then put it inside a condom, which was tied shut with about five different knotes, then glad wrapped yet again a few times, then taped up[ with sticky tape.
I wore underpants underneath my boxers for the event, so I could tape the package to the front of my underpants, then ditch the underpants when I got my goodies out (which took a while because it was so well packaged, or so I thought). Anyway back to the entry. Just before ID Check rthere was a nice looking labrador on quite a long leash sitting next to a policeman, not really bothering anyone. I saw it sniff a few hands but not go after anyone, everyone must of dropped before hand. Anyway I walk past and the dog seems to like me. It walks along side me sniffing me, then runs back to the owner. I think PHEW. Two seconds later its beside me again, sniffing, it is called back. Then about five seconds after, it runs back to me, at the full extent of its leash basically sniffing my crotch like crazy. I show the dog no fear, but I look down to it and give it a "I wonder why the dog is sniffing me" look, I did not look at the police at all. It is called back with "Here boy". Then as if it tried to run towards me again I hear it running just behind me and the cop yells "Sit boy"...
I looked through this forum and collected as much ideas I thought would work as possible, and the dog still knew I had drugs on me. Why wasn't I searched? Maybe because the dog was sniffing right at my dick, and not my pocket so they couldn't be bothered strip searching me, just incase the dog was wrong. Maybe I was only number 23 sniffed out of 50, and they only seartch every fifty, or whatever number, maybe becauise I didn't look at the cop and just shrugged the dog off. Who knows. But a dog will smell throufgh anything is the lesson I learned.
