Dogs to the Rescue: Bomb-Sniffing Dogs

People began to train dogs to be bomb sniffers in the 1970s. Dogs have an excellent sense of smell and can cover a large area in a short amount of time. Trained dogs can smell and find explosives much faster than people. Bomb-sniffing dogs learn to identify different explosives, weapons, and materials used to make bombs. These include dynamite, gunpowder, and plastic explosives.
