Thanks to some wonderful advice from here, the ability to apply it, and a horse willing to learn, we have conquered the rail to the right...... and lightly so..... apparently my horse is very light after he understands what is being asked, so the last two passes to the right, I touched his hair (thank you to whoever gave me the hair,skin,side, kick imagery) and he would go back- even better he only strayed twice during the canter to the right.
I am writing things down so when I get frustrated with him not being all the way trained, I can look back and see how far he has come. He is amazing!!!!! My smart little-almost-five-year-old.
Success!!! Good boy Citrus.
