ABSTRACT
Historical dog training methods reveal that dog training then and now might not have been that different. While some methods that would be considered unacceptable today have vanished over time, much of what we do today has been practiced historically for a long time. Albertus Magnus' De animalibus and Petrus de Crescentiis' Ruralia commodia deliver us historical evidence on how dogs were perceived, kept and trained by our ancestors. Not only were they already kept as pets, but they were also used in a wide range of professions. Dogs were utilized as guard and watchdogs, for hunting and for herding and livestock protection. Dogs are still trained in many of those professions today. From these historical records, we can learn how the perception and use of dogs has been similar or very different from our view on dogs today. We see how certain training methods have persisted over time, giving us an opportunity to ponder on new training and handling methods for man's best friend.
ABSTRACT
The extraordinary capabilities of the canine nose are increasingly being used by law enforcement agencies in many countries to solve and reconstruct crimes. As a result, this type of forensic evidence can be and is still being challenged in the courts. So far, only a few publications have addressed the jurisprudence concerning mantrailing. We provide an overview of the jurisprudence in Germany and the USA, as well as insights from France. Relevant databases were searched, and 201 verdicts from Germany and 801 verdicts from the USA were analyzed. As a result, 16 published verdicts on the topic of mantrailing were found for Germany, and 44 verdicts since 2010 were found for the USA. The use of mantrailers and human scent discrimination dogs is employed in the investigative process in all three countries. The results derived from these methods are admissible as evidence in court, albeit not as sole evidence.
