Thats one of the most adorable things I've seen in a long time.
Dog tape : D
Maybe it is a toy (Fluffy toy) dog??
I love the many bicycle-dog photos these days! I recently got my first dog - a lil chihuahua and since I ride a bike, he rides a bike too! Not his own, but carried with me in a front facing messenger bag. When the weather warms up he will be carried in a basket, much like the dogs featured in your blog recently!
You could never get a smooth fox terrior to do that!
I want to get my cat to ride with me. Then i want my bird to ride with us. Basicaly, I want to be the crazy bike/animal lady : )
