When Bigo the service dog saw an oncoming mini school bus heading for Audrey Stone, the blind woman he was trained to guide, the golden retriever’s protective instincts kicked in: He threw himself at the closest part of the vehicle he could.

Police photos show the result: fur stuck to the front driver’s side wheel and in the middle of Michael Neuner Avenue in New York, where the bus came to a stop after striking the pair.

The driver of the Brewster school bus, carrying two kindergartners to St. Lawrence O’Toole Childhood Learning Center, told police he didn’t see the pair crossing the road as they made their way home at about 8:15 Monday morning.

But Bigo saw the bus coming and leapt into action.
