Wisconsin man's dog barks for help after farm accident

A Wisconsin dog is being hailed as a hero for saving her owner's life.

Bob Kumbler was trapped by his skidloader on his farm when its bucket malfunctioned. Pinned by the heavy machinery and barely able to breathe, he realized he didn't have much time and wondered if anyone would find him.

His faithful dog Holly recognized he was in distress and started barking.

We'll let Bob take the story from there.
