Next to all the scooter every one loves here, why not just build a dog trailer to tow behind you?? For in town only under 45 MPH I ve seen people add bike trailer to scooter as a sidecar. For low speed that is ok if you pay attention to the wheel bearings on it . Some People build Box racks to put there dogs in. For bigger scooter you can find vepsa, honda elite 80 to 250 cc , Yahama Riva 180 and others. As for scooter trailers do a google search to see what people have build. On total rukus website I ve seen a sidecar build for a dog.
