ABSTRACT
Adapting these inherent canine skills involves long periods of training, and this requires that police take advantage of the high level of interspecies communication unique between humans and canines.2 Even species closer to humans from an evolutionary perspective, such as chimpanzees, are of considerably less use to us (and we to them, admittedly). The canine sense of smell explains the majority of their police functions, and their association with us in shared environments explains the rest. It is appropriate to survey aspects of canine biology that are relevant in understanding how their adaptation to us has been transformed in police work.
