If you have to "persuade" him to do it that does not speak of a much better than the behavior you are describing with him under other riders. As to the bond/leader, if that were the case you wouldn't be having to "persuade" him to do what you are asking....nor does the fact htat he "puts up with" rather than willingly doing.
A few points on your reply
First point: You seem to have mistaken me for the original poster. Which I am not.
Second point: I was not aware that young green horses newly backed came with all the knowledge and experience to handle anything you put in front of them. My mistake I will have a chat with him and tell him that he needs to grow up and realise he is a big horse and not allowed to worry about anything.
Third point: I state im a novice so yea I do think he "puts up with" alot from me. I do not have the best balance, i'm not yet the sharpest with teaching him queues for things. But the fact that he works through it with me (yes with me) rather than dumping me on my butt (which would not be a hard task) I think shows that he does infact do things willingly for me!
Forth point (more for the heck of it): I have a very well behaved boy, who can hack out by himself happily, who will calmly take any position when out with other horses. His first trip to the forest he took the lead and didnt look back, however is also happy to bring up the rear. He is polite, moves out of your space when asks, heck when carrying a feed bucket I just have to look at him with my "mare glare" (which I practice in the mirror) and he will immediately back off me, put his head down and wait for me to walk away from it. I think all this combined with the fact that I am a novice, I have only a years exprience working with horses I am doing pretty well with him.
Ok rant over now.
