A small neighborhood dog proved to be too tough for a couple of armed robbers in Altadena, California.

When the gun-toting men burst into a Erik Knight’s tobacco story, the normally laid back ‘Paco the Chihuahua’ sprang to his defense, nipping at the robbers legs and eventually chasing them across the street.

“He was rescued, so I suggest everybody rescue a dog from the pound,” Knight told KABC. “You never know when you’re going to need him.”
