Apollo BUCKED. Under saddle. *gasp!*
I have to laugh, though. It was a straight up and down buck, not the buck and twist that Reveille could get going. He didn't drop his shoulder, just humped up and bucked. Hee.
He only did it at the canter, only late in the ride, only on the right lead, and only three or four strides after the depart. He bucked a little; I said "quit that" and asked for the transition again. He bucked again; I growled "Stoppit," took off my spurs so as not to be inadvertently spurring him and causing it, and asked for the transition again. He bucked a bigger buck; I said "FUCKING STOP THAT!", hopped off, and longed him at a canter for several minutes. He didn't really want to canter or keep the canter, but I had to make a point. I'd already conceded the point by dismounting, but even though I wasn't having any trouble riding the bucks, I don't need a fall right now. So I found a different solution.
So we'll see how he is today, whether he's sore or what. I hope it was just attitude after not getting ridden Wednesday.
