Have you noticed why defense personnel keep sniffer dogs? No? The purpose of the sniffer dogs is to sniff items around and detect for any illegal items present in those items. You might wonder how a dog decides which one is illegal and which one is legal, and even if it does that, how can it inform the humans about the validity of the item.
