A guide dog that was undergoing testing and training seems to have passed the biggest test of all when he helped save the lives of his two trainers.

Two employees, one who was blindfolded, were out walking with O'Neil the lab, training him as a guide dog. One was acting as a spotter for the two when he noticed the dog jerk his head back. He turned to check it out, only to see a car barreling backwards towards them. Thankfully no one was hurt, and O'Neil is going to make a great guide dog for someone in the next two to three weeks.
