I tried teaching Lacey how to hobble....didn't go too well. Haha
I did teach her to lead by her feet though, in preparation for hobbling but now it's just a cool thing she does.
Basically, I'd first work on desensitizing your girl to her legs being touched by things, etc.
Then, what I did with Lacey (she's GREAT with her legs/feet though), I would run a soft lead rope around her front leg and kinda run the lead rope up and down her leg. Once she was good with that, I started leaving the rope down behind her pastern or knee (knee was easier for her to figure out at first, I progressed to doing this with every section of her leg once she was good with the "easy" joints) and I would put a little pressure on it. As soon as she made any move forward, I let up on the pressure. She never freaked out but if she had, I could just drop one end of the lead rope to "free" her.
Once she was totally cool with that, I used a mini horse lead rope with a tiny clip on it and I clipped the lead rope into a loop that I looped around her pastern and tightened up. I guess this way was sort of practice for if she every got her leg fully wrapped in something bad... We repeated the same "a little pressure=forward" thing and she figured it out quickly.
She's so good at it that now I really could just loop that lead rope around her leg and take her somewhere, no halter necessary.
Of course, that could be dangerous so I don't, but I could.
I tried to hobble her once she was pro at the leg thing but she would fight the hobbles scary hard. She would be find just standing in them but FREAK OUT if she tried to move. After having her freak out (rearing repeatedly, nearly falling, getting really really scared, etc) twice, I just gave up on the whole idea. Her physical and mental health is more important to me than her ability to be hobbled.
She's shown me (through the lunge line, inadvertently and unexpectedly, getting tangled around her feet, etc) that she knows to stop, stand, and move into pressure around her feet so I figure that all the work I out into teaching her lead by her feet worked enough to be important. Maybe she just has a mental hang up about being hobbled, I don't know.
Anyway, try teaching your girl to lead by her feet and then try hobbling, but really don't try hobbling. It's pretty scary and I dunno, I'm put off it now! Haha
If you really want to get her hobbled happily, have a trainer do it. It's not worth you getting hurt/her getting hurt/etc.
Of course, she's not Miss "I'm going to throw a fit about the strangest things!" Lacey, so she might be totally fine with it once her feet are all desensitized.
I think desensitizing her to things around her feet and teaching her to give to pressure on her legs/feet will be the first step in any case.
