A plucky chihuahua went toe-to-toe with a pair of shotgun-wielding robbers trying to rob a California smoke shop -- yipping furiously and chasing them out of the store.  

Wearing black hooded jackets and armed with a rifle, the two thieves burst into a tobacco store in Altadena near Los Angeles demanding money, according to USA Today.  

However, when the owner began handing over cash from the till, his tiny pet started barking frenetically.  

The diminutive dog named Paco refused to be intimidated, even when one of the robbers pointed the barrel of his weapon at him, eventually chasing the men out of the shop and down the street, USA Today reported.
