That's what I feel Horton and I are taking together, and I'm a happy woman! I sense a major shift in his attitude, and believe "remedial lunging" is behind us (the line is still in the arena, though, just in case).
Today I did lunge him in a surcingle and side reins, though. Yesterday when I rode, I asked for – and got! – canter both directions, but the right lead was a real struggle. It took lots and lots of urging for him to finally pick it up – and then he'd lose it within a stride or two. Well, that was the first time. He picked up the right lead canter four times, and each time he held it for a few strides longer, but it was clearly a challenge. So today I wanted to be able to watch for clues to a solution while he worked, hence the lunging.
There were no waving red flags, just a horse that is a little less balanced and strong when circling to the right. I was very encouraging and he honestly tried to comply with all my commands. In fact, he was such a good boy that when we were done lunging, I stripped off everything but the bridle, led him over to the arena fence (where he stayed close enough for the first time!), and slipped on him bareback. I finished cooling him out at the walk, asking him to reach down and flex his neck and poll from side to side.
So it has been a momentous week already – and it's not yet half over!
