It's nerve-wracking watching the dog in this video jump in front of this man's car, but after you watch you'll know just why he did it.
The dog was jumping and barking up a storm, staying in front of the car for a full 30 seconds even while it was driving down the street.
When he finally decides to give up, the driver accelerates quickly, but he'll wish he hadn't...
Unbelievable, right? Dogs really are man's best friend, even if we don't listen to them as often as we should!
