I put Lenny's photos up yesterday and to my mind, he has a healthier and more robust caudal hoof already than he had when he arrived. The test though is always in how horses are moving, and finally (after some really annoying glitches with my Mac which have had me wanting to throw it out of the window) I've managed to upload it.
Lenny has changed his landing quicker than some horses, but he had a reasonably good frog and digital cushion which is always a help.

His landing has improved but his stride has shortened - this is a common but temporary issue, due partly to the fact that he doesn't yet have the best shock absorption and partly due to the changed way in which he is using himself now, as opposed to 3 weeks ago.
There is lots of work to do but he's made a good start.
