Dog sports range from the incredibly fun to the potentially life saving, and the category that search and rescue falls into is most definitely the second of the two options! Search and rescue was taught to certain breeds of dog centuries ago to help them to find people. Of course, the majority of those dogs were to rescue people from hazardous conditions but there were a few that were trained to find humans in war conditions as well. In more modern times, dogs are trained to seek pests, criminals and so on!
