I've often wondered what my dog, Chester, does when I leave the house for the day. I assume he does the same thing he does while I'm there - sleep. But, after watching this video, I fear he may have the same reaction as this dog. And that makes me never want to leave the house again.
A man hooked a GoPro camera up to his friend's dog to see what the pooch was up to while the humans were away. The resulting video is kind of heartbreaking.
