Tracking dogs follow a person’s path from a starting point to where the person is. These dogs are able to seek people because they are trained to discriminate human scents. In other words, they don’t seek for any human scent, but for one particular scent. There are two main types of tracking tasks: wilderness search and urban search.  Since these dogs discriminate odors, they need an uncontaminated odor sample (from something the person has touched or wore). They need a starting point (location the person was last seen or known to be) and the tracking process can begin.

This is a highly successful way of finding answers should there be a criminal case. It also allows you to monitor your own area, find out your weaknesses in terms of perimeter security and anticipate any criminal actions that may occur.
