Owner teaching a foal to load on trailer

Teaching Quidditch to load on a trailer for the first time. He was apprehensive so I did the same I do with all when teaching. I tie the lead in the front in a quick release knot and then gently tap on the top of their rumps until they step forward, as soon as they give you one step you stop tapping, then reward. Repeat over and over, never hitting, just tapping. After time they will step on and then jump on. Quidditch was at this for 8 minutes so I gently nudged him on and he was fine. He got on and off 3 more times after this with zero issues.
