My dog used to ride with me all the time until he back legs got bad. I made seat extensions to widen the back a little and what she'd do is jump up on the seat behind me, stand on the seat and extensions, and ride there. I ride with my cargo box and she'd just lean back against that. If it started to get really rough, I'd shift back and lean against her to help hold her. We've been over some really rough and steep stuff, and she's never had an issue. Breaks my heart now though because she can't ride anymore due to her legs, but will come running with that look on her face anytime I start it up.....
