Sky is Back

So we went down last Sunday to ride Sky. It all went well until I took him in his stall to get the bridle on, so he wouldn't bolt out the door. (we have been doing this since he has been acting up) I got his halter off fine, but he would not let me get the bridle on! I put my finger in his mouth, that still didn't work. When i finally got him to take the bit, he clenched it between his teeth and held his head up high. Since we only had an hour to begin with (we had to head to a soccer game), i decided to give up on the bridle even though i didnt want him to think he could get away with that every time. Then i couldn't get the halter on, i tried for 40 minutes, he would turn around, put his butt to me, and put his head in the corner. I finally left him in his stall and mom called barry to let him know why he was in. Sandi then decided she would go down tuesday. She called, he was fine. Then i had a lesson on wed. he was fabulous, he didnt care about the bridle on or off, he didnt spook at anything, he was great! I went down again today and rode. He was as normal as could be. Whatever it was, it went away as mysteriously as it came!
