This video proves dogs really are our best friend. When Kaylyn Marie was locked out of her house, she thought she’d be stuck outside for hours. But her good pup Sam had her back. To unlock the sliding glass door, someone had to remove a wooden rod blocking the door’s tracks. “It freakin’ slipped back in,” Kaylyn lamented in the video she shot when she got locked out. Kaylyn got Sam to paw away the rod until he was able to pick it up with his mouth and unlock the door for her. Then Sam tried to play with the wooden rod — because what else would you expect from dogs?
