The remarkable stories of the 71 heroic animals who have received the pet equivalent of the Victoria Cross are told in a new book.
They include a dog who dragged his drowning handler to safety in a torrent of shells and machine gun fire and a carrier pigeon which flew 120 miles to raise the alarm for a bomber crew who had crashed into the sea.
