The sense of smell is the primary sense used by Explosive Detection Dogs, but they are also trained to use other cues such as changes in behavior, or body language of handlers, indicating an explosive hidden.

EDD's are extensively trained to locate a wide range of explosives including dynamite, TNT, C4, and other plastic explosives, and homemade explosives, etc. They are also trained to detect illegal drugs and firearms.

The training process for Explosive Detection Dogs can take several months to a year or more. They start with basic obedience training and then move on to more advanced training, such as learning to detect specific odors. This process requires a lot of patience and consistency, as the dogs are gradually introduced to the scents they will be expected to detect in real-world situations.

Explosive detection dogs work in a variety of settings, including airports, ports, train stations, and other transportation hubs, as well as in government buildings, sports stadiums, and other public places. They are also used by law enforcement agencies during investigations and to search for explosive materials during raids.

It is a very important task and Explosive Detection Dogs play a key role in ensuring public safety, as well as supporting law enforcement agencies in preventing the use of explosives for illegal activities.
