Dogs detect scent from a source that is carried to them in a plume
by the wind. The most important tool for a detector dog handler to
have on searches is a knowledge of scent plume movement or "scent
dynamics" (the science of scent movement). Such knowledge resides
primarily in scientific journals that are largely inaccessible to
detector dog handlers and written in language that is difficult to
understand. Detector Dogs and the Science of Scent Movement: A
Handler's Guide to Environments and Procedures retrieves, reviews,
and interprets the results of pertinent scientific research on
scent dynamics and presents these results in terms that are easier
for handlers to understand. Information on the physiology of the
dog's nose, their sense of smell, and the properties of scent
provide the essential information on the process of scenting. The
composition of training aids for explosives, narcotics, human
remains and other sources is discussed. Recommendations are made on
the use of training aids, their placement during training, and the
resulting availability of scent. Potential problems and handler
errors in the use of training aids are also examined. The
characteristics of scent plumes and how wind influences their
movement are a key focus of the book. The primary task for the
handler is to get the dog into the scent plume so that the dog can
detect the scent and follow it to the source the handler seeks. As
such, a knowledge of scent and scent plume movement will vastly
improve the ability of the handler to accomplish this task. The
influence of weather and physical settings such as terrain,
vegetation, ground cover, soil and water on scent movement are
examined in detail. Strategies for searching, detecting, and
locating sources in all physical settings are presented. Specific
effects associated with hills and mountains, fields and forests,
bare soils and soils covered by vegetation, different soil types,
and lakes and rivers are examined in detail. This includes specific
recommendations are made about weather and physical settings that
result in higher probability of success on searches. Detector Dogs
and the Science of Scent Movement will be a vital resource for K9
handles in the private and public sectors-including in Homeland
Security, law enforcement, and military settings-as well as a
useful guide for lawyers, forensic, and investigative professionals
who need to better understand K9 operations.
