Without boots, he was slightly "short" on firm ground at a walk, and had a definite "nod" at a trot--lame but not "dead lame." Worse yesterday than the day before--no sign of thrush or a rock or anything, purely his own feet.
I put the boots on, with some help. In five minutes, he was walking sound on the firm ground, and at a jog trot had such a faint "nod" that if I hadn't known what to look for, I couldn't seen it as an effect of the booties. I had Richard lead him over the sand hump as the acid test of "it's his thin soles flexing too much' and he didn't flinch or shorten stride. Good news!
So...he stays in boots for awhile., unless he gets them off (he did that last time.)
We have now had two working sessions (simple ground work--leading, halting, turning, backing) and he is much more responsive if I have a dressage whip in hand. But he also worked better the second session than the first.
That's it. Back to the chapter.
