Right, now I'm home from school I will add more..
I live on a big dairy farm which varies from completely flat land to massive hills and ponds, a few foresty areas and a river. I also live in a very quiet area so the roads are usually pretty quiet, although I haven't gotten to the stage of trusting him enough to ride him down the road yet, as our neighbours.... How do I put it..... Drive very wrecklesy(sp?), to put it nicely.
I'm in the process of trying to desensitise him to random things while i'm not on him (because when he spooks he does so very quickly, and with very big movements) so far he doesn't give a flying whoop about hula hoops etc, but god help me if I wave a butterfly net around him just yet... I figured I would get him used to the net first before I introduce the plastic bags that make scary noises haha.
lots of circles and bending in and out of cones ect, work on lateral work and keep him going stopping and starting keep varying what you are doing to keep him interested,
I have been doing lots of circles, but I'm working on desentistising him to cones as I have the big "scary" bright orange road cones and every time he see's them we both fly across the paddock with not so much as a second thought... Atleast I know he can leg yield :L.
That's what I was doing the day he threw me off, I think he got fed up with not being able to anticipate me, so he threw in something (a few of them) that I wasn't anticipating at the time... He's now learning you just do not do that.
If you do any dressage, that's your best bet. With a horse like yours, you really need to keep his mind engaged. Dressage, more than any other discipline, seems to keep the horse focused on the rider. When he starts to show signs of short attention span, play the 8 strides game. Every 8 strides, do something different. Leg yield 8, straighten 8, shoulder-fore 8, straighten 8, change gait 8, etc.
Also if you can very things more by jumping a few days a week, go out for a trail ride a few times a week. Anything so he's not doing the same thing on subsequent days.
Yep, I do mostly dressage with him because i'm trying to establish that while I weight less than he does, i'm still in control :P. That and the pain in the bum fact that he works more on the forehand than properly, I'm finding that part hard to get him out of though... Hillwork possibly?
I have jumped him once since I've gotten him, for two reasons... One being he is far bigger than bubbles, and has a huge (and I'm talking MASSIVE) canter stride so I'm trying to adjust myself to that after having a short backed, speedy and choppy horse.
The second reason is I have this massive paranoia that because I know he has bowed a tendon before that he could do it again.. If I plan to do heaps with him I put boots on him, but I'm guessing that I should probably work on this whole, 'use your hind end properly!' thing before jumping him to much seeing as the tendon was a front leg, even though it was little.
Also try and do the opposite of what he expects. If you mount on one side, try varying it. If you usually get on and immediately start walking forward, stay still for a second, then turn around and walk. Etc.
I tend to mount on one side because i'm ******ed and just can't manage to do it from the other side haha, but I might try that eventually. I tend to make him wait a bit before he goes anywhere because I "adjust my girth and stirrups" while i'm on him.... Actually I just sit there playing with them for a bit because I had the staying put problem with bubbles and I don't want him to get into the habit.
