This German shepherd is visibly confused ... why? It will make you smile!

If you've ever see a dog chasing its tail, and the image made you laugh, then you will find this video adorable! The German Shepherd has just discovered that there is something called a shadow and that it is impossible to catch: although he's really trying hard, his "prey" always manages to escape. In the end, like any self-respecting noble hunter, he must surrender.
