Mary Hartman, 91, slipped on a patch of ice as she was attempting to deliver cookies to a nearby neighbor. Hartman called for help, but it was a cry that only neighbor Judy Sawatzki's Jack Russell terrier mix, Taz, could hear. "He would run to the window and come back to me," Sawatzki said. "He would whine and bark, and then go back to the window again." That's when Sawatzki let Taz outside, and the terrier mix shot down the driveway barking for her to follow. Taz led her to Hartman, who was crying for help on the icy driveway.
