Search and Rescue
Search and Rescue means searching for and providing aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. Search and rescue dogs have saved thousands of people over the last few decades.
Just as people distinguish colors and objects with the help of their eyes, dogs do so with help of their highly developed sense of smell. The human body emits odor molecules from breath, sweat, urine and more. The dog picks up the odor molecules that fly through the air and tracks them until it reaches the highest concentration – the missing/trapped person.
During the search, the dog performs a free scan in the area as directed by the leader.
When the dog reaches the missing person he will mark him by barking, and will not stop barking until the dog handler reaches the missing person.
