Ways to mislead/stop police dogs 2?

Here's the archive file, Ways to mislead/stop police dogs - Archive file (http://www.roguesci.org/theforum/showthread.php?t=2306)

I want to know more about this subject, so (after googeling for 5 seconds) i found this page. FM 32-10 Chapter 8 Tracking/Countertracking (http://www.globalsecurity.org/military/library/policy/army/fm/23-10/Ch8.htm) Not that it's good or anything, i just thought i'd add it.

Anyways. So if you know that police dogs will come, how would you throw them off? If you have some time before they come, speed up. Try to get as far ahead as possible, since you move faster than them. Eventually it will loose your scent.
However, apart from backtracking and running in circles to throw them off, would physically leaving the ground - say, running for a while then getting up and riding a bike, or into a car - eliminate the trace somehow?

Say, you knew police dogs would arrive in [Single digit] minutes, what would be the BEST way to mislead or stop them?

Change your scent dramatically. Pepper, scent deadners, chilli, air freshener, whatever. You have two options, one is to change your scent on your body, the other is the change the scent on whatever they are going to use to scent the dogs for tracking you. Obviously, changing the scent of your jail blanket, etc. is going to be far faster and easier, and won't wear out so fast. You'll need to pass over some other scents first, a shared area, or whatever, else the dogs will eventually pick up the only scent around anyway.

Scent is fairly airbourne. There are two types of dog, general dogs and human scent dogs. See http://www.dog-training-specialist.com/mantracking.htm

When the soil warms during the day, the scents will rise, letting the dogs track faster. At night as the temperature drops, the scent will too, and slow the search. I've heard there are two types of tracker dog, air and ground. Air dogs can follow a scent that is in the air, and ground dogs can follow either. However, I'm fairly sure this is more concerned with the length of time since you passed by.

The use of water may help mask scent, but I don't know how effective it is. Don't forget that there are smart (or at least trained) people with the dogs, who will know that you have to leave the river/stream eventually. Likewise, running in a circle will mean they have a 50/50 chance of getting to you right away, and even if they go around the circle once, the handlers will prevent it happening again.

Best advice I can give is to do the scent thing first, then try to go to places the dogs can't, like scale a cliff or ladder or something, so they waste time taking the dogs around. Get to a vehicle, preferably an enclosed one. Use a car, a bus, etc. to evade, and add range. Most importantly, it will keep your scent from falling to the ground.

The last trick would be to set up something to physically stop those following you. A tripwire and a handgrenade will stop the handlers, if not the dogs, and then the system is broken.

Mutts don't like the smell of ammonia. Even a little bit around the immediate
area fucks with their sense of smell. I'm sure there are other compounds that
can achieve this effect.

Thanks for the suggestions.

So, do you know of any other irritant smell that one could use to distract a dog?
A grenade might be a little bit extreme. Is there anything that i could use as a substitute? Something that will not kill or maim, and preferably not harm, but stop them dead in their tracks? Some kind of booby trap with pepper spray or other irritant?

Completely filling the air around the scene with different smells which will make it hard for the dog to pick up the one it's supposed to?

Any other ideas are appreciated. Thank you.

I forgot:

Would houshold ammonia, found in cleaners such as maybe Windex or something similar do the trick? Emptying an entire bottle at the scene or something similar?

I worked with search dogs for a while. There is nothing you can do in a "single digit" when running on foot short of physical violence against the dog and handler. Leaving the ground, climbing a tree, etc. is futile against a properly trained dog & handler. As noted, cold weather and also DRYNESS make a track harder to follow, but warmth and humidity can bring back your trail for up to several days. Diesel exhaust will drastically reduce a dog's ability to scent, when working disaster scenes such as avalanches you must keep the heavy equipment away from the working dogs until they have indicated where to dig...

I have read an account of a blood hound who successfully followed an abducted child's scent down a freeway for several miles from the air blown out the car's ventilator. The dog got to the correct off ramp before collapsing from heat stroke, and a physical search found the kid's body.

What about a couple of pill bottles filled with chloropicrin dropped behind you so that they smash along your trail. A dog would come to it, sniff, dog down.
Next dog/handler team will bypass this, then hit another trap in a well chosen location.
A couple of these, a good couple of dog teams down. How many dogs are the police willing to waste on you. They dogs might either just not like the smell, become incapacitated, or die from the chemical, depending on what concentration they sniff.
