Well done at your show!!
One of our younger Dales sometimes gets a bit iffy with loading. I have found that to stop pulling on the lead rope, give it some slack, and quite often they walk in without a problem, once they think you have given up. Also a light tap with a schoolng whip on the hocks moves them onto the ramp, and in. We did have one really stubborn pony, and got a person either side of the ramp to stop it stepping off, each holding a lunge line, which them tightened round the ponies bottom, had a few minutes of it trying to go back, but it went in fine.
