Humans and canines have a long history of working together, with the use of hunting dogs stretching back to perhaps 20,000 years ago. And in some cultures, it seems ancient shamanic practices related to hunting success have extended to their four-legged partners: according to a new paper in the Journal of Ethnopharmacology, at least 43 difference species of psychedelic plants have been used in cultures around the world to allegedly improve the performance of hunting dogs.
The researchers focused on the Ecuadorian Shuar and Quichua people - who use at least 22 species "for ethnoveterinary purposes" - trying to determine the possible pharmacological basis for the use of these plants with hunting dogs:
The use of psychoactive substances to improve a dog׳s hunting ability seems counterintuitive, yet its prevalence suggests that it is both adaptive and that it has an underlying pharmacological explanation. We hypothesize that hallucinogenic plants alter perception in hunting dogs by diminishing extraneous signals and by enhancing sensory perception (most likely olfaction) that is directly involved in the detection and capture of game. If this is true, plant substances also might enhance the ability of dogs to detect explosives, drugs, human remains, or other targets for which they are valued.
