The two men were in the middle of an armed robbery at a Southern California cigar store on July 7, according to The Huffington Post. The store owner began putting money in a backpack when Paco the super Chihuahua went ballistic on them.
Apparently, the robbers got away with about $200 in cash, so Paco's not a complete hero, but nobody was injured so it's still a good story. I'm not a dog lover, but this dog's got some real cohones. I think.
