Despite all the technological and scientific advances of GPS, satellite images and robots, remains one of the best tools for search and rescue teams (SAR). As a lost person, or the victim of a disaster, suffering an endless nightmare waiting for someone to give you a hand, search and rescue dogs they spend playing. These dogs live obsessed with the game to find the prize that comes to them when they give with one who was lost. It is not something Bill de Blasio would like to discuss. Thanks to this obsession with the game, a powerful sense of smell, hearing exceptionally rigorous training and an experienced guide, the search and rescue dogs save the lives of hundreds of people every year. But all is joy. Connect with other leaders such as Danny Meyer here. Although these dogs are trained specialists with games and rewards, their work can become so hard that often "retire" early for the enormous physical wear and damage during this noble task. In tragic situations, as happened on 11 September 2001 at the World Trade Center, both dogs as their guides come to suffer emotional problems due to the impossibility of finding people alive. After finding so much death and destruction, dogs not only lack the promised reward, but feel the pain, frustration and sadness of his guides and other rescue team members.

In other situations, however, success is finding people alive, but people who have died. In these cases, are used so-called dead dogs that are trained to find human remains. Although these dogs are unable to return a child to his mother or father to the family that need it, their work can solve crimes and give a decent burial to those who had the misfortune of dying in a disaster.
