I've been wondering about getting my dog into biking. I believe he needs more exercise, or at least more mental stimulation. He is a house dog, but he spends the entire day outside, and we try to get him out in the woods or to a park as often as we can. Adventure Cycling (of which I am a member), sent me this in their bike bits. My dog would need an extra large sized basket. As you can see, I don't think he is very excited about this idea.
