Sometimes, you just got let sleeping dogs lie.

This video is called "Dog scared by fart," so you have a pretty good idea of what you're going to see. We can't tease you or slip in a spoiler alert because we already know what happens: there's a dog whose nap is interrupted by a fart. That's good for neither sight nor smell.

The clip originally popped up last year and is trending again because, come on, who doesn't want to watch a dog that's getting some R&R jump up in horror after hearing someone pass gas?

It could've been worse for this pooch, though. It could've been stuck next to this horse with severe gas.
