You should know by now, not to leave your dog unattended in a vehicle. It can be really dangerous to their health, and as it turns out -- it can also cause hearing loss. Check out the video below, but first maybe turn down your volume a little.
No one knows what is going through this dog's mind. Maybe it hates traffic as much as the rest of us. Maybe it's hard of hearing and doesn't realize it's making a scene. Whatever the pup's motive, that face it makes at the end shows it doesn't care what you think.
The funniest part is that this has happened before. (Warning: these videos are loud.)
