I'm not trying to come across as harsh, but I saw the same that JDI did. Clippy could be a good barrel horse, but from what I saw, you should not be even walking the barrels right now. Right now, he sees the barrels and gets all tense and starts popping up on you like he did. You, either as a result of him or for another reason, are getting tense as well.
I would just work on dry work and no barrels until you can get him retrained. The more that you run barrels on him, the harder he is going to be to retrain.......
I can not stress enough how important it is for you to get him off barrels. He is getting sour and getting into some very bad habits. In order to be a good barrel horse, you need to take him back to basic training. Right now I see both you and your horse being in danger. I don't mean to sound over dramatic, it just worries me. If there is anyway I can help, always feel free to PM me
I have realized that he is unbalanced. But when I move barns I am getting him retrained. Thank you for your input!
I see a hospital visit in your future and I'm scared that your horse will become unmanageable and dangerous. I'm scared for the safety of you both!
