. If I am riding a horse that is sloppy and unbalanced at the canter, I will either point them across a pasture or pick up a large circle and lope and lope and lope until they feel right. You can't do much as far as collection and such until the horse is comfortable and able to balance at the canter and they can't get comfortable and balanced at the canter without doing a ton of it. For the first quite a little while on my green horses, I will just give them their head and only correct them enough to keep them going in a large circle. Everything else they have to figure out for themselves, how to balance, how to rate, how to flatten out and relax. I don't give them the bit to balance on or my legs. After they do all that, then you can start working more towards collection and refinement at the canter.
