Dynamic canine tracking method for hazardous and illicit substances

A method of implementing vapor wake detection in a defined location to be monitored, comprising:

• positioning a canine in the defined location;
• sampling the air with the canine for a plurality of vapor wakes simultaneously generated by a plurality of people, wherein the plurality of people are moving, and further wherein the plurality of vapor wakes are thermal and aerodynamic plumes of the plurality of people that come off of the plurality of people as they move through the defined location;
• detecting a target odor in one of the plurality of vapor-wakes from one of the plurality of people with the canine, wherein the detected vapor-wake includes the target odor;
• and
• recognizing by the handler a change of a pattern of behavior of the canine when the target odor is detected by the canine
• wherein when the plurality of moving people are moving, and moving generally in the same direction, the canine is navigated utilizing leash manipulation prior to the detecting in a side-to-side manner behind the plurality of people while the canine moves within the plurality of vapor wakes in the same direction as the plurality of people in order to detect the target odor,
• wherein when each of the plurality of moving people are moving, and moving generally in different directions, the canine is positioned and navigated utilizing leash manipulation prior to the detecting in order to take advantage of any available air currents while the canine is moved in and out of the plurality of moving people.
