A couple years ago, a stray dog showed up at a gas station in Mexico. The employees at the gas station started feeding him, gave him attention, and even brought him to the vet to get shots. They named him 'Randy' and he became a favorite of employees and customers. One night as Randy was sleeping, one of the employees began closing the store. That's when a couple of guys tried robbing the place. A fight ensued, Randy heard the commotion, and chased after the men. Surveillance video below.
