. So, I think he has been top dog for several years! lol You bring up a good point. Maybe I can put him in a herd with other horses and let them give him an eye opener. I wonder if I can find something affordable. How much time would that take??? Three months or six months. ???
This is a problem because if he is top dog with horses, he thinks he will be top dog with you. To get him to fully
submit, the amount of force from a human would be abusive so I think the best bet would be to just keep him in line. The best best best thing ever would be to find an alpha mare that is more alpha than him, or even two alpha mares. Maybe that would mean bringing him to another stable or talking around because if he is forced to submit, there will be a huge change.
About the biting and him biting you 20 minutes after a correction, that is perfectly normal for a dominant horse. He is testing you, he will always be testing you and every time he tests you, you have to pass that "are you fit to be my leader" test. You must be consistant.
. I was longing him daily for 25 min w/t/c and he would pull his shenanigans everytime. I would us a shank over the nose and the longe whip on him. The severity of the correction went from mild on up until he performed the action I wanted. He knows what I am asking. He is thinking about whether he wants to do it. I also growl, and sometimes that helped.
I want you to do something different. Ask him to do whatever you are asking and if he doesn't then give him a warning growl. Then if he doesn't do it, he gets the harsh correction, not the mild one. In the herd, the lead mare doesn't start out with mild nips if she doesn't get what she wants. She'll pin her ears back as a warning and then if the horse doesn't listen he gets a big bite on the butt. You see if you start out mild with him,(because he already knows what you are asking) he will think "oh, well she gave a warning growl and if I don't listen I will get a pointless tap on the bum. hahaha" but if you do give him a harsh correction right after the warning growl he will think "oh, if I don't do what she wants, I get in trouble, I better do what she wants". You'll be like an annoying bug if you don't show that you mean business. You'll be teaching him to listen to you after you ask him five times, not after you ask him once.
