You know when you say I hope they get the same treatment........... (very NSFW)
After Tom-Jan Hüschs girlfriend broke up with him, he decided to take revenge to an unforgivable level by hitting the very dog his girlfriend brought him as a present multiple times. Worst of all he decided to film it all and upload to Facebook.
Warning. This footage you are about to see is very distressing. I have to admit, probably one of the worst I have ever seen. It really is - the original video is at the linke below, but unless you have a very strong stomach I advise against watching (I couldn't).
This video was since removed from Facebook however this footage went viral attracting the attention of one man who decided to bring this little dog justice by tracking down Hüsch and inflicting the same pain he did on the poor defenceless dog. This guy also took a video of himself beating up Hüsch which he later posted online as a warning to show that animal cruelty and abuse will not be tolerated in Germany.
