If you needed a reason to never, ever go out again , this is it. A man with a GoPro attached the camera to his dog while he left the house for the day to see what the little guy gets up to, and it turns out there's at least three minutes and 47 seconds of despair (hopefully for the rest of the day, the dog was just napping or, better yet, hanging with the human). Though, on the bright side, the overwhelming excitement your pooch feels when you get home probably wipes the lonely memories of the day from his or her brain faster than you can say "dinnertime," right?
