My instructor doesn't seem to think it is his teeth causing the issue, because he completely behaves once the bit is in his mouth. He isn't tossing his head, chomping, etc. or showing any signs of discomfort. Also monitoring how he eats, and he isn't dropping a lot of grain, etc. I am however still going to get his teeth floated, but I'd prefer to have an equine dentist that uses hand tools do him vs. our vet who uses power tools. One of the other boarders uses a woman who comes from out of state once a year who does a really, really good job. She is supposed to be coming back early April, if we can hold out til then I'd like to have her do him, otherwise I'll call around.
Today before our ride, we didn't lunge him (first time I rode him without lunging) and got him from the pasture and right into a single tie just with the rope slid through the ring, no knots. We had the rear barn doors shut in case he decided to bolt, but he didn't. He stood there, got antsy at some points, but he actually was okay. Cinched up, walked him around a little, placed the rope back through the ring, then finished cinching. Reason I did him in a single today is because me personally I much prefer a single tie vs. a cross tie. We were limited on time today, but I still kept him in the tie for as long as I was able to.
I was loaned a different bit to try today that was supposed to be a little lighter weight than my eggbutt snaffle, but I much prefer the way he rode in the egg but, so will probably be returning to my usual bit. He has been an absolute nightmare to bride, but today my instructor worked with him after our ride for a bit, and when she came out of the stall with him, I was wondering if something bad happened, and she said "he actually took it nicely that time." We're working on having him spit the bit out when removing the bridle, instead he close mouth tosses his head up, which we're working on breaking him of that. He's making slow, but sure progress.
I am thinking if this method works with the breaker ties in fixing the insta-panic when he steps back and feels restrained, maybe the tree tying will help him learn to stop being so impatient ALL the time, lol.
