In today's wacky animal video, security camera footage from Ace Smoke Shop in Altadena, California shows armed robbers being chased out of the store by the shop owner's raging Chihuahua. The robbers did manage to make off with some cash, but the LA Times notes that it was "less money than they could've gotten."
