I have a trainer that had me thinking I was crazy. I took him a horse, didn't sugar coat a thing, told him all the crazy stuff she did and how I was totally at the end of my rope. Basically told him she was Linda Blair in the Exorcist. So......first 30 days, he asks if I sent him the wrong horse, she's so sweet but nervous. Just works herself into a nervous sweat every time he rode her or worked with her, but manageable. LOL! I was impressed and it convinced me that I was to blame, so I paid for the 2nd 30 days......and the switch flipped. He called me after 4 more days and said, "OK, you weren't crazy, lying or mistaken. This mare is nuts and I'm wasting your money, please come get her." She ended up kicking at her stall neighbor before I got there and fractured her leg, so ended up being put down.
I have since sent him 3 more horses and they have all turned out wonderful! Very sane, calm and super easy to ride. Unfortunately, he's in OK not TX or AR, or I'd suggest you send your horse to him.
