Kelly is absolutely right! You should wait until 18 months for your dog's safety. But, after that, there is a great site about biking with your dog. It is written by a woman who owns dobermans, but it applies to any dog. She uses a Springer, available at lots of online dog supply stores. Here's the link: http://homepages.udayton.edu/~merensjp/ ... index.html I hope this helps!
