In our monthly Skype session, Hannah and I discussed some "crazy" behavior Aslan was doing. I would ask him to do stuff at liberty and he was getting very excited and even occasionally pointing his bum at me. I've never really had him do this, so I was pretty shocked. He didn't actually threaten but it was a bit disconcerting. I had sent the video to her and she saw his behavior as boy play and said that Toby did the same thing; he would even kick out.
We agreed that it came from the liberty class at the Gypsy show. Male horses love the "come in and chase away game" which is exactly what we did. Now I understand these emotions and not to push them so far; instead reward coming back down. He has improved. I can ask for a few steps of trot on the ground and he will gently transition instead of going bonkers the moment we start to move. Hormones and other things can also come into play, including a change of season. Aslan definitely gets mood swings during season changes. Note to self.
The mugging issue we started having is also much better, and using a cone or target to give him something to do other than "nothing", helps with the self control. He tries really hard to keep his head straight and I've seen him correct himself. Aslan is a foodie and will probably always struggle, but when he does mug at least he is sweet about it. I'm trying to also be more cognizant of asking him to keep his head straight as he takes the food. Even after you click and as you feed, you are rewarding what is going on in that exact moment as well. Head straight is what I want to reward.
