I'm not a big fan of videos in general. Because I have to concentrate so hard at work, I seem to have the attention span of a gnat when I am home or not working. So it is remarkable that I not only watched this fascinating YouTube once when I came across it on StumbleUpon, but watched it several times. Obviously this contraption took a long time to create from concept formation to reality. And it was built by someone who obviously adores his dog, Jerry. And it is one smart dachshund that learned how to entertain himself, likely for hours on end. Jerry seems like a very happy dog. I hope you enjoy this YouTube as much as I did. The only remaining question is ... how can I get him to build one for my energetic Tibetan Terriers?
