In World War 2 dolphins were trained to place explosives on the hulls of ships, dogs were used as antitank operatives, and pigeons were trained to guide missiles − although the birds’ skills ultimately were never called upon. Examples abound throughout history of animals doing weird and wonderful things that we would never expect or imagine. Ancient Egyptian paintings show hyenas (which we know from Lion King are not easily submissive) on their backs, being hand fed by humans. Animals as unexpected as guinea pigs and geese have been used as guards to warn of intruders. Dogs working with anti-terrorism forces are sent case samples to be scrutinised for their expert opinion.
