This is absolutely awesome. I went to a predrink party at a friends house this weekend. There was a dog. Its name is Doug. Doug is seven months old and doesn't really know he has a tail.His balls have been removed so he has to do something for fun. What Doug does it chase his tail. Watching the video below you will notice that Doug does not seem to realise that his tail is attached to his body. Doug will chase his tail in a circle, get dizzy and give up for a bit. Doug will then get excited, wag his tail and get irritated that the foreign object is hanging around again and begin chasing once more.Brilliant:
