Thanks, everyone! For some reason I wasn't getting notifications for this thread.
Ian, do you have any specific exercises you'd recommend working on for improving my ability to move his feet? I've been doing some side passing along walls, lunging with a lot of direction changing and stopping him facing me in between, and flexing his neck without swinging his hind end on the ground (he does it fine under saddle), but I'd love suggestions for more groundwork exercises to work into our routine.
Wallaby, I've heard people suggest "the evil eye" approach, and it makes sense. I'm going to make a point of making myself more intimidating when I'm making demands — obviously I would never want him to be afraid of me, but until he learns I'm in charge I think I need to be a little more formidable :p
gssw5, I will try this. I was wondering about doing it after a ride — I thought about it but wasn't sure if he'd associate "punishment" (being made to stand) with riding. I know standing isn't a punishment, but right now since he clearly doesn't want to stand I'm guessing he sees it as one.
churumbeque, I think that about horses sometimes, too, and dogs, but I am the least fidgety person I know! I really don't think I give off nervous or high energy that he'd be feeding off. I think he just doesn't think he has to listen to me.
DustBunny, I've heard the crop suggestion, and I think I'm going to try this. I was hesitant about the idea, but I'd rather him start to stay in his space by getting smacked a few times until he learns than nagging him and begging for the rest of my life, since clearly my gentler requests are not being heard ;)
Sharpie, he's 10, and supposedly he was his old family's trusty trail horse, so I think this is about me rather than him, which I guess is the better case? Hehe
Crystal, I will try this! How do you suggest moving him in the cross-ties? Just side to side and front to back for a minute?
