There's a whole tradition of dogs in sidecars you should check out! There's even a documentary,Sidecar Dogs! http://www.sidecardogs.com/ And if you'd rather read a blog, check out Mallory Paige's blog, http://mallorypaige.com/operationmotodog/. She started from 0, bought a KLR and welded up a sidecar, and has been on the road for more than a year now with her lab. It rocks completely.
