A guide dog in training alerted his two trainers to a runaway car that was barreling down the sidewalk in San Rafael, California.  The dog's jerk of it's head alerted Todd Jurek, who was walking the dog and another employee.  Jurek quickly herded everybody to safety and seconds later the car rolled through right where they were standing.

Nobody was hurt, including the driver of the car, a 93-year-old woman.
