Gent, my paint TB, I recently gave away after a year long struggle with him rearing every time I asked him to stop or slow down. My trainer and I did everything we could think of to change his behavior, with no luck. Even sent him to the cowboys for a month. He came back as wired as ever. Heres a picture or two of one of the many rears captured on film/image. I just wanted to know, is there anything anyone can think of that may have caused this. Because he was in perfect health, not a sensitive mouth, not an overpowering bit (he was a hard mouth), and he had no ailments or history of it. He just went insane one day, and never recovered.
