Detection Dog

A detection dog or sniffer dog is a dog that is trained to and works at using its senses (almost always the sense of smell) to detect substances such as explosives, illegal drugs, or blood. Hunting dogs that search for game and search dogs that search for missing humans are generally not considered detection dogs.

There is some overlap, as in the case of human remains detection dogs (sometimes called cadaver dogs), trained to detect human remains. They are also used for drug raids to find where the drugs are. In the state of California, dogs are trained to detect the Quagga Mussel on boats at public boat ramps, as it is a invasive species.

Sniffer dogs have also been enlisted to find bumblebee nests. The Bumblebee Conservation Trust has trained an English Springer Spaniel to detect the colonies, assisting them with the conservation of threatened species. Some prisons have dogs trained to detect illicit cell phones in prison cells.

Detection dogs have been trained to search for many substances, including: Bed bugs, Human remains, Currency, Drugs, Explosives, Firearms, Mobile phones, Mold, Polycarbonate optical discs such as DVDs (used to search for bootleg recordings), and Termites. One notable quality of detection dogs is that they are able to discern individual scents even when the scents are combined or masked by other odors. In one case at an Australian prison, a detection dog foiled an attempt to smuggle drugs that had been hidden in a woman’s bra and smeared with coffee, pepper and Vicks Vapo-rub.

A sniffer dog can detect blood even if it has been scrubbed off surfaces. In one case, a sniffer dog sniffed a drop of blood on a wall although an attempt had been made to scrub it off. It was so small that it couldn’t be seen without a microscope. Some of these functions can be carried out by trained pigs, which also have an excellent sense of smell, and have been used to hunt truffles for centuries.
