Thanks. Would you mind explaining how to train them to flex their necks and break at the poll? Yeah, we are working on the stop cue on the lunge line. As far as the buddy sourness, I can't seperate them very well, only to the point where they can see eachother, but not touch, and when I did that, they were still attatched by the hip.
you just need to go back to the basics and teach him to soften up-- grab the rein, pull his neck around, keep doing so till he does it easily-- I would go from doing long pulls, to doing small bumps to soften him up, it will also make him really soft in the mouth.
As for the flexing at the poll, when you pull the reins you want him to bend his neck not pull away from you, or throw his head up in the air-- to achieve this, I would also do the bumping technique. He will bend his head down farther and farther the more you bump him.. you don't want to be bumping straight back, but in an upward type motion.. I would get him backing up, when bumping him. This will show him you want his head down..
For the buddy sourness, he is attached at the hip to his friend, because he knows you're not the leader, and you can't make him listen to you so he does not. You need to show him you're the leader, and his attention needs to be on YOU! Get his attention, every time he calls for his buddy, I would make him do something to get him focusing on me, weather it be pulling his head in my direction, or lunging him a few circles. He needs to know You're in charge, and what You say goes, and he needs to pay attention, and Respect that. If he doesn't respect you, he doesn't see you as the leader, and won't listen to you.
