'Ruff' justice: Guard dog -- Chihuahua -- attacks armed robbers

Posted: Updated:

It’s not the size of the "dog" in the fight, but the size of "fight" in the dog—and this "little" terror proved who was tops!

Two armed men were caught on security video storming into a smoke shop in California and demanding money.

As the owner handed over the cash, his pet Chihuahua attacked both suspects and chased them both out of the store.

Both the dog and the owner of the shop were unharmed.

The suspects got away.
