When a bomb-sniffing dog sits down on the job, it means there may be explosives nearby. But to the dog, it only means one thing: a treat is on its way. Bomb-sniffing dogs have saved many lives doing the dangerous work that, to them, is just a game. See these super smellers in action in this fascinating book for growing readers.
