Anyway, today when lunging (I always lunge him, even if it's for a second, to see what he'll be like, and let him warm up his back - he is cold backed). Today he wasn't being so good.
He was fine (very hyper!) but fine, and then randomly he fell out and took off. I didn't have gloves on, and thank god no one was in the arena, so I let go (I tried to hang on, but he's REALLY strong when he wants to be). I got him, put him on the lunge and got him going again. He did the same thing - fall out and try to gallop off. I couldn't hold on (again, yes he's VERY strong...trust me!). That led to me having many blisters on my hands that were bleeding, and him being really nervous.
What could I do to prevent this? He does that sometimes, and I don't let him get away with it (I scolded him today), but usally recoves. Today, however he kept doing that until I physicaly had to stop (also, I was sick and couldn't chase him for hours and don't have my full strength back). He might have just been feeling good since he just got his teeth flooted and the chiro came out.
Thank you, and everything will be considered.
