We have been spending some time in getting Bella accustomed to her mobile dog-basket aka the sidecar.
She's had some treats in and around the sidecar, this next stage was to get her into it - with a lead and collar and plenty of praise & strokes. Then we started and stopped the engine a few times and the last stage was to drive a few feet across, then up and down the drive. Finally, we left her sitting in the sidecar, with a couple more treats ...
Mission successful !
