Dog running behind biker

I love dogs and mountain biking so for me this video is a great combination. It's shows just that a dog running a mountain biker and the dog keeps up the whole time he stays right on the biker's tail. After seeing this video makes me want to take my dog out while I mountain bike and see how well he does with keeping up. I will have to do this when no one is on the trail so he doesn't scare anyone. LOL

Here's the video link enjoy. LOL

He's very fit so I think he will keep up with me on my bike. I know he will have a great time.
