Open you’re inside rein to allow your horse room to move over. Let me know if it helps!!
I also have this problem!! I just got home from a clinic and this is what the clinician told me. Instead of doing a full circle to the right and asking for the lope, cut down the middle of your circle (like a half moon shape but straight down center)then turn holding your bend down the side of your half moon shape so then when you are turning to go up the center of your circle, ask for the lope. This way as you are asking whilst turning and your horse is bent to pick up its right lead. If you don’t pick it up turn in a tight circle to the inside and drive your horse forward and try it again! I found it helped me!! Now we nail our right lead every time! 💪 (sorry if my explanation got confusing I’m horrible at explaining things😂 )
if it is for exhibition take it in a short one if not I recommend a loose one I hope you serve what I say and in case of not solving the question sorry
