I have my (recently put under saddle) arab colt with a great trainer who uses about half natural horsemanship and half not, which I think is a great combo. I am wondering what kind of things I should focus on with training my horse so that I can ride him tackless someday. I want to prepare him to not be dependent on artificial aids. How do I do this? I know the basic things to do, like not relying on reins to signal him things, etc. but are there any specific strategies that you guys know of?
