Trained dogs save lives, but once in a while the dogs put into practice their skills when they are not needed.
Take for example this life guard dog. He saw an unattended child in the water and thought the kid was in distress. Naturally, the pet jumped into action to saved the kid. The problem was the child didn't need to be rescued.
The underage swimmer had a life jacket on and his parents were nearby watching him, but the rescue dog thought it would be best for the child to be out of the water.
Watch the funny rescue.
