Hitler, Goring, Himmler...the three architects of the Final Solution. But these three men, like many other high ranking Nazis, shared another obsession: a fascination with the animal world. In the last days of the Nazi regime, Hitler risked his life every day, leaving the safety of the bunker to walk his beloved dog, Blondi. But the Nazis’ interest in creatures went beyond love of their pets or the animal welfare laws they introduced.

Whether it was experiments to create the purest bred of horse, transforming German Shepherds into tools of terror or trying to resurrect the long extinct wild auroch, they sought to control and purify the animal kingdom - practising the principles of eugenics they would later apply to humans.

This documentary investigates the secret programmes to control the animal kingdom. A fascinating journey into the world of Hitler’s creatures.
