I also just found a post on another forum that some people may find useful:
In reply to the question of beating sniffer dogs, it really comes down to whether your expecting to encounter dogs or not,
If your not expecting to get sniffed, theres not much you can do to avoid or beat it, but if your carrying lots of drugs around often, a little sonic speaker is probably a good investment.
When entering a festival theres a good chance that you will get sniffed, so take precaution, put your drugs into balloons, tie them off, and wash your hands and the balloons in the sink, partly for drugs and hygiene
if doing this just before the festival, be careful about what you were carrying them in before you ballooned them, those jeans that had the pills in the pocket will smell!
its a bit more effort to open them in the festival, but it beats a conviction.
Wear the drugs up high, either a folded bandana on the head or a hat, or even in your mouth.
The whistles and speakers can be effective, but come with their own risks of getting caught.
One of the smartest and funniest things I have seen done is rubbing your shins with citronella oil (the orange insect repellent for tiki torches). Dogs really dislike the smell of citronella, and it is used in barking training collars.
I was waiting for the gates to open of a festival here in Australia, and a guy started passing around a spray-pump pack of citronella, I reckon the first 200 people through the gates must have annoyed the shit out of the dogs
And I would expect they would find it hard to smell anything else through the scent, so if you dont mind smelling a bit like a tiki torch, you could try that trick!
And last but not least, avoid being sniffed!, work on your side stepping skills, and pay attention when your running the gauntlet!
