It is a sunny winter day. Tim is going skating on the lake. Tim puts on his skates. He does not see the sign. Tim skates on the ice. It is fun. Suddenly he fall down the water. The dog crawls slowly to Tim. He takes Tim's jacket in his teeth. He pulls him out of the water. Finally a man finds them. He calls 911. The ambulance comes. Tim is safe. The dog is a hero. His picture is in the newspaper.
