To be honest, I don't really understand equine behavior. I first rode a horse at overnight summer camp when I was seven-years-old. I was kind of a nasty ill behaved child, and I understood that the "ranger" in charge of the horses was pairing me with a short chubby horse (Stubby) with a similar disposition. From the moment we met, that horse and I were compadres. To the bewilderment of everyone, when I was on Stubby, he was angel. When other kids tried to ride him, he'd leave the trail, stall, maybe even decide to run back to the stable.
Years later, my first wife and I were living in Duluth, MN. She was a lifelong equestrian, competing in hunter/jumper competitions. At the stable where she was riding, we were offered to buy a former race horse, now gelded, supposedly six years old, for the price the owner would get from a Canadian meat processing plant. My wife said he was a total bargain, very trainable. I didn't know anything, but thought he looked nice and he always nuzzled me when I got close. I did have a veterinarian examine him, who gave him a clean bill of health.
I was totally clueless what the cost of a box stall, feed, farriers, veterinarians, etc. would be. After we had the horse for a few weeks. the ex said he was harder to train than she thought he would be, but she would persevere. My ex rode an English saddle that was literally crafted for her. I have only ridden western saddles. Occasionally, on the Q T, I'd go to the stable, throw a western saddle on him and just go for a leisurely ride. There were times during our stroll when he'd stretch his neck toward me and give me the "look" which meant "I'm going for a run." I held on for dear life and I swear, when he slowed to a trot, he was laughing. The ex always was pissed when she found out I'd put a western saddle on him and just "gave him his head" as she put it.
The marriage didn't last long. I looked for a buyer for the horse, but was unsuccessful. I ultimately found a camp that used horses in a rehab program for children. Fortunately, it was a 501(c)3 as I paid for the horse's upkeep until he passed, about a decade later. I did get a nice annual tax deduction and photos.
There was no way on God's earth I was going to sell him to a meat processing plant. I think he knew that.
