Developing reliable Historical Human Remains Detection (HHRD) dogs requires more than simply burying training aids in freshly dug holes.
Historical burial environments are complex systems where odor interacts with soil chemistry, moisture, microbial activity, vegetation, and time. To prepare dogs for these challenges, training must extend beyond basic burial exercises and incorporate scenarios that more accurately reflect real-world conditions.
In addition to training in historical cemeteries, Cairn Canine Detection is incorporating elements of Paul Bunker’s burial protocols to provide controlled opportunities for training aids to interact with soil over time. This approach helps expose dogs to more realistic odor presentations and supports the development of the low-threshold odor recognition skills required for historical and archaeological applications and old cold cases.
As with any detection discipline, realism in training is essential. The closer training conditions mirror operational environments, the more meaningful the resulting canine performance becomes.
Our goal is not to teach dogs to find a buried training aid. Our goal is to develop dogs capable of recognizing and responding to the complex and often subtle odor signatures associated with historical human remains in real-world environments.
We remain committed to advancing evidence-informed training practices and improving the reliability of HHRD canine teams working in support of historical, archaeological, and culturally sensitive investigations.
