AQHsam- Our experiences sound very similar! We started with a bit, went to a hackamore, and now I'm back to the bit. My horse just loves stuff in his mouth. It can be a rope, metal, wood, food, ANYTHING! lol. He just loves to act like a baby and put stuff in his mouth. I know it's probably a bad habit, but as long as I'm careful with my stuff, it doesn't bug me too much. I don't like when he is more focused on grabbing a shank in his mouth than listening, but if we are just hanging out, then I don't find it to be a big deal. I'm just so glad that he had a bit to play with today.
