One dog owner wanted to know what his dog got up to all day while he was out of the house, so he filmed a timelapse video.
He leaves the house around 9:00 am, while his dog starts the day with a hearty nap on the couch.
As the clock in the foreground ticks away the hours, the pooch moves again and again, but also barely moves at all.
There's a shocking and hilarious conclusion, so watch the video to see what happens when you let sleeping dogs lie. It's the answer to a question every dog owner has wondered at least once.
