Search and rescue dog

The use of dogs in search and rescue (SAR) is a valuable component in responding to law enforcement requests for missing persons. Dedicated handlers and hard working, well-trained dogs are required in search efforts to be effective in their task. Search and rescue (SAR) dogs detect human scent. Although exactly what this means to the dog is not known, it may include skin rafts, evaporated perspiration, respiratory gases, or decomposition gases released by bacterial action on human skin or tissues. Search and rescue dogs sometimes are worked from horseback.
