Letter from the renowned dog trainers Lt. Colonel Edwin Hautenville Richardson to the Royal Society of Arts, confirming that he would give a lecture for them on the subject of dogs in peace and war. He also makes suggestions about other talks he gave. Richardson was well known for providing guard, sentry and police dogs and lobbied for dogs to be used more widely at the front during the First World War in line with other countries. Eventually, he was asked to set up the British War Dog School at Shoeburyness (later it moved to Lyndhurst in the New Forest) where hundreds of dogs were trained to act as ambulance, sentry and, in particular, messenger dogs with great success.
