Lucky The Doberman.
One of the Doberman Pinchers used by the Marines in the Pacific in WWII was “Lucky”. He was used, like many of the other Dobermans, to locate Japanese snipers using the dogs’ smell, hearing and vision. During one successful mission where multiple snipers were located, Lucky’s handler was wounded. Lucky stayed beside him until he was found. But when the medic started to render first aid Lucky growled, but then relented when he understood that his handler was being helped. But when the handler died and the medic left, Lucky wouldn’t let anyone else approach. To retrieve the body the Marines had to throw a noose from a distance over Lucky’s head to pull him away. That kind of loyalty was typical with war dogs, which were closely bonded to their handlers.
