Detection dogs

The chemical composition of C. sativa is very complex and about 500 compounds in this plant are known. A complete list can be found in [81] with some additional supplementations [2,82]. The complex mixture of about 120 mono- and sesquiterpenes is responsible for the characteristic smell of C. sativa. One of these terpenoic compounds, carophyllene oxide, is used as leading substance for hashish detection dogs to find C. sativa material [83]. It is a widespread error that dogs that are addicted to drugs are employed for drug detection. A9-THC is an odorless substance and cannot be sniffed by dogs. 

Despite recent increased interest in canine olfactory and applied EDD research, we stiU lack a complete and robust scientific model of the way dogs actually detect substances however, considerable progress has been made [5]. In particular, it has proved helpful to apply similar concepts to the detection dog and handler system as would be apphed to an instrumental detection system. For example ... 

Presently, US explosives detection dogs tend to be German or Belgian Shepherds, Malinois or Labradors, but there is more variation within a breed than between breeds [22]. Selecting a dog or breeding a dog with optimal olfactory capabilities has only recently been emphasized. Yet, for centuries animals have been bred to perform select tasks. Perhaps olfactory detection has lagged behind in this... 

Canines are a proven operational tool for substance detection, but as a practice, canine detection remains more of a craft than a technology. The quasi-technological state of detector dog technology fosters variabiHty in detection capability and reliabiHty, resulting in varying degrees of skepticism. Nevertheless, canine detection is used as the basehne capability to which instmmental devices are compared. Furthermore, despite aU the unknowns and uncertainties, there are stiU many situations where detection dogs remain the best or, indeed, the only available option.

At a large workshop of about 150 dog people in Ljubljana, Slovenia, some years ago, the case for mine detection dogs (MDDs) was debated. No consensus was reached. There were just too many opinions, stresses, and uncertainties. The work group at the GICHD started basically with the same problems but through the persistence of Havard Bach and others the problems became less.

Once a landmine is deployed, a complex process begins in which the environment near the mine becomes contaminated with explosives and explosive-related compounds (ERCs) derived from the charge contained in the mine. It has been known for decades that mine detection dogs can detect the chemical vapour signature of explosives emanating from landmines [1]. More recently, detection of landmines by vapour-phase sensing of key... 

Because of the use of TATP by terrorists, a rehable and fast detection of this material is desirable. In addition to conventional analytical methods such as mass spectrometry and UV (ultra violet) spectroscopy specially trained explosive detection dogs (FDD) play an important role in the detection of organic peroxides. Although the high vapor pressure helps the dogs to detect the material, it is also a disadvantage because of the limited time-span in which the dog is able to find it (traces may sublime and disappear forever). Matrices in which the compounds can...
