Don't mess with the little guy with the big bark at the Ace Smoke Shop in Altadena, Calif.
The Los Angeles County Sheriff's office released some amazing surveillance video on Monday, showing what happened when armed robbers stormed into the shop on July 7.
They left with some money, but less than "they could've gotten," as the Los Angeles Times reports, because of the owner's Chihuahua. His "ferocious barking" and lunges at the bad guy's legs look to have convinced the robbers to clear out quickly. No one was hurt.
