Exactly, horseluver. I'm not saying you were hurting him on purpose, Roper, and it is just natural that you trust in what your vet says. It's just not acceptable for me and is a thing I wouldn't do with a young horse, if I was responsible for one, that's all.
I've got a light draft myself and his breed matures very slowly, so, even with him being already 6yo, I still don't ask him to work in full capacity. I can wait for those joints and vertebrae to mature fully until I start serious jumping and such. But that's just me.
I have come a long way, to surrender my shadow to the shadow of my horse.
