When we got my very first horse.... (at the time 3, now 22) he was like this. Would not stand still. We tried everything. So finally we took him to the bottom of the property away from all other horses to an old trailer never used. And tied him with 2 halters and 2 leadropes, a bucket of water. He stayed tied there for 8 hours. He learned to stand still after that.
Many people have sighed for the 'good old days' and regretted the 'passing of the horse,' but today, when only those who like horses own them, it is a far better time for horses. ~C.W. Anderson
