@OGIONIK,
Basic obedience, which is necessary to give control to the handler. The second stage involves exposing the dog to different people from a wide spectrum of types. It is also exposed to different scenarios that may imitate the future missions. A rescue dog needs to focus on finding the human without getting distracted by adverse environments.
The last stage of training is the search and indication. The handler wears a vest on the dog to signal the start of the rescue work. Training involves using a toy to play hide-and-seek with the dog. When the dog finds the toy, it is removed from it which makes the dog bark. This is the indication training that mimics the indication of a human found by the dog.
