Now on view in the museum library: "Search and Rescue Dogs from the AKC Library and Archives!" Featured in this exhibit is Lt. Col. Edwin Hautenville Richardson, who began training dogs for the military in 1900. His techniques were extremely progressive for the time: he practiced reward-based training and positive reinforcement. He vowed to never treat the dogs he trained with cruelty, and above all prioritized trust between dogs and handlers. He believed dogs had souls and were sentient beings. This all sounds standard now, but in 1900? Pretty revolutionary!
