With that being said the poor guy is stuck on stall rest for the next few months, and as you can imagine he's bored and hyped up beyond belief. I try to take him out for grass but the second another horse walks by or the dogs on the farm start to play he gets all excited and wants to play too. Except his version of playing involves leaping on all fours, rearing, flailing legs and strike outs. I expect this seeing as he's in a stall 24/7 and as much as I correct him he just gets more worked up. Then the second he's back in his stall or on cross ties he's quiet as can be and an absolute joy to be around. Again, I can't blame him for being worked up and expect him to act up but being as large as he is and how crazy he gets I'm getting nervous.
I have worked with OTTB's before but not to an extent or situation like this. I'm kinda at a loss of what to do and all the advice I have received is to yank on the chain lead more which I feel is going to do much more than upset him or drug him until he can be turned out.
Any other ideas on what I can do to teach him this is not acceptable and or any tips on how to handle this.
