A lot of attention is given to the dogs that sniff drugs, money, fugitives, lost and trapped humans, but not a lot of public attention goes to the cadaver dog.
Not that they care.
Like all sniffer dogs, the cadaver dog is highly trained and cares only about finding the scent and getting a reward.
After the search-and-rescue dogs are finished at disasters, sadly the cadaver dogs are brought in to recover bodies so that they can be given proper respect by the survivors.
Unlike search-and-rescue dogs, which are usually taught to bark excitedly when they sense a living human, cadaver dogs are mostly trained to sit quietly or lie down when they detect human remains.
They also are used widely in crime investigations to locate bodies or parts of bodies which may have been hidden or buried. Even if it is no longer there, dogs can detect traces which criminals have tried to conceal. They are trained to detect the difference between human and animal remains. Cadaver dogs can even detect decomposing human remains through concrete.
Working from a boat, water cadaver dogs can locate the odor of a drowning victim and assist divers in finding the body as quickly as possible. They are trained to react only at the spot where the scent is the strongest.
While cadaver dog is not the glamor job of the working dog world, their contribution is just as important and they are happy working for praise and noms.
