One of the more dramatic uses of dogs is in searches for human remains. Today On the Dogwatch we have the great pleasure of speaking with Cat Warren, who has experiences in both training cadaver dogs and also in writing about the field of human remains detection using dogs. We discuss aspects of the research that Cat did for her book What the Dog Knows, the process of using dogs to detect remains, the sensitivity of dog noses, and how they are being used currently for archeological purposes.
