SAR dogs are "Search and Rescue" dogs. They are specially trained to track and find lost people. SAR dogs were used in the World Trade Center disaster to search for victims buried in the ruble of the twin towers.

Dogs have 25 times more olfactory receptors than humans do. Their noses are structured to process scents efficiently and their brains are wired to interpret olfactory information better than human brains. Dogs can sense odors at concentrations nearly 100 million times lower than humans can. For example, they can detect one drop of blood in five quarts of water.

SAR dogs are trained to use this superior scenting ability to help their human handlers find missing people. They might search for a child or mentally challenged person who has wandered off, for a person lost after an accident, for a victim trapped in debris, or even for a person who has been abducted.
