For what ever reason you may want to evade dogs or if your being chased by the police then this article is for you. This article is for educational purposes only or for if you are a POW.

[edit] Steps

Learn that when you are being chased the searchers will be looking for footprints, old campsites, survival shelters, discarded equipment, human waste and other signs. Also if you're in the countryside farmers will be able to spot tracks or other disturbances and will contact local authorities.
Know that the night time is the safest time to move. This has the advantage of allowing you to move when its is cold(so you don't perspire) and to sleep when it is slightly warmer. However this may not be possible in difficult terrain such as mountains, jungles or swamps. Other obstacles like slopes, cliffs, tree roots or branches can cause serious injury as well as create unnecessary noise. If doing this use a long thick stick to probe in front of you.
Learn that your route should skirt around heavily populated area like cities, towns, and suburbs. If someone does see you you should:
Put on a bold front, don't appear "furtive," this arouses suspicion.
Get some "normal clothing" nothing flashy or expensive.
Keep clean.
Beware of children and dogs(they are the first to notice strangers).
Never move on roads. If crossing a road, and if necessary use a diversion. At night, use the noise and light of a passing vehicle to make the crossing.
When resting you should only rest for 5-10 minutes every hour and jog. When resting choose naturally cover like a big , dense bush. For overnight stops fallen trees, large bushes or fallen pine boughs will provide concealment.
Blood Hounds.These dogs are most likely blood hounds and as a result are mush harder to evade. The vulnerability of these dogs and the team is that the dog and the handlers are connected by a long leash and the stamina of the animal must be match with that of the man. Your main defence is to make evasive movements to destroy the handlers confidence in his dog as well as to move faster than the team.
Attack dog. This dog is released to attack and detain the you. Its main weakness is that it must work apart from its handler and in its overconfidence; in training it is always allowed to win. When being attacked by it you could use a stick to club it at the neck or try and breaking one of its legs. Alternatively if you're still standing you can surprise it by falling on it and taking the opportunity to break its leg.
