I have a 7 year old ottb who is now starting eventing. He has lovely movement, and can easily jump 3'. The problem is that he cannot do a lead change.
When he is on the wrong lead he easily gets unbalanced while doing tighter turns on jumper courses. Occasionally he will do a right to left lead change, but never left to right. He is off the track, so the right lead is harder to get than the left lead.
If I am on the left lead and go over a pole on the diagonal, he will do an easy change with the aid. When I subtract the pole, he does not understand the aid.
Do you have any suggestions on how to teach him the aid for lead changes?
