Stoopid hot here too. Must be summer.
Tio, despite having lost his right front shoe and having troubles with a loose left front shoe, insisted 100 degree heat is a great time to go for a nice long ride down the roads. Even though getting to soft sandy roads meant going down a steep, gravely one first, he marched with great joy and determination. After 2+ miles exploring, I finally got him to head for home and into the slightly cooler breeze. So long as he was on sandy or grassy ground, his feet didn't bother him at all, and all these jaunts out have developed a a really nice swinging, over-reaching walk. I just wish the shoer would get his hind quarters out to my place so I can do more with T than just walking.
Rudy and I worked as usual, with me trying to get more consisant cadence in the trot and more sit in his new and improved canter. For some reason (I never did figure out why) he was highly resistant to canter hp to the left on Saturday. To the point of literally just shutting down and not moving. He had one of his "I don't WANT to stand still and wait for traffic" fits on our warm-up ride out and did a lot of backing up (his idea, not mine), so maybe he tweaked something? I truly have absolutely no clue. All I know is something was bothering him and there was certainly no point in arguing about it. When he has these melters, I stay very quiet and back off to a simpler version of whatever I'm asking for. In this case it was walk ly, then si, then si-to-renvers, then si-to travers, and then finally, walk hp from wall to centerline. Rudy doesn't protest unless he feels that he can't comply, so I never get after him, I just try to find what he CAN do. SO Sunday, after he was well warmed up and doing really flowy canter hp's to the right and cantering well to the left, I went from an 8m volte into a short left hp but it was really hard to maintain the bend. Refreshed with a medium canter, did a 10m circle in travers, refreshed again, went back into the 8m volte and asked for shallow hp again with only 3 strides over, 3 strides straight, 3 strides over and straight down the centerline(ish).. He was at first hesitant but by going straight right away he didn't have time to worry. Then the next go round, did volte into hp to centerline easy peasy.

His reward was a big rolling training level canter, followed by a gorgeous medium trot acquired entirely from my seat and then down into a confident, swinging medium walk. Whew! We were both dripping wet but he was clearly quite pleased with himself and even me, his task master. He is such a special little horse; it is a real honor to be his rider/trainer/friend.
