I brought him inside and put his cooler on to try to help him dry a little. The rain started coming down so hard that there was a small waterfall on the side of the arena and I was glad that Kai and I made it to the indoor arena in time. I groomed Kai for a while and massaged his back and braided his mane so that it wouldn't get dreadlocks because of the wind. I then left him tied in the corner for a while so that he will begin to learn how to relax when tied.
When I came back I decided I could play with teaching Kai to trot super slowly. The way I did this was by walking on the rail with a good rhythm and when Kai was relaxed and in sync I brought up the energy very slightly. If I catch him by surprise and don't give him enough warning he hollows his back and makes a tense transition. I gradually walked faster and faster until Kai did a few steps of very slow trot to catch up. I praised him and gave him a break and then continued to ask for more steps. Soon Kai could trot beside me down the entire long side of the arena. I asked him to do some canter circles and some trot circles making sure he stayed bent to the inside.
I began by walking at stick to me and slowing and shortening the steps and then walking normal again. Soon Kai began to match my tempo and would slow down with me. We also did the same thing at the trot. Then Kaila suggested that I put him in a corner and ask him for a step forward and back until he got the idea of moving in one place. I modified it by standing in front of his driveline having him between me and the wall and putting energy behind him so he would think about moving his feet. We played with that for quite a while and worked through him resisting and swishing his tail and kicking. Kai was freely moving his hind legs but he would plant his front ones.
I kept working on it until he got unstuck and offered a little step and we quit.
