This year, he's been different. He has very high energy, and it can be tricky to control him at shows a few times (would be fine in warm up, but once he got in the arena, he couldn't stand still and was acting like a stallion, quite honestly). Even at home, he seems hyper all the time. I've had people look at him (horse people), and they tell me he doesn't scared, nervous, or in pain. I've checked out my tack, and the way it fits him/me, and it is no different than in years prior. His feed has been the same as always.
Starting this year, he's also gotten clumsy. He slips and trips all the time! I keep him collected (rounded body, not just the headset...actual collection) but he still does it. At first I thought it was the ground that I school him in (it is a cleared out pasture...not completely flat) , but he does it at shows, too. It's not the shoes, because he does it even when he's barefoot.
Anything you guys can think of??
