Who is jumping on you? I did not see anyone being rude or making smart remarks. If you are going to ask a question about a horse that has very dangerous behavior, you got to be able to take the advice, and not just what you want to hear. Sure, Northern's reply was a little on the harsh side, but in all reality, very true. You have been asking your horse to run, run, run with a painful saddle and anxiety problems. Of course he's going to lash out.
Yes, we may be asking you questions you don't want us to answer, but we can't just assume the answer without asking. It's not rudeness. It's asking for more information so we can better understand the situation.
And if YOU were paying attention, I mentioned many other things to do in addition to trail riding. (So knock your attitude back a notch or two.) Trail riding is great and all, but it has nothing to do with an arena, and that is where you horse has an issue. You've got to work in the arena where you horse has the issue.
He hates slow work right now, I suspect, because all he knows is RUN RUN RUN and he's confused and frustrated. I stand by everything I said in my previous post. Stop running this horse on the pattern. Do exhibitions on him only, at the walk or trot. Enter in some reining classes. Enter in some low level western pleasure classes. Do some cattle events in the arena. Any SLOW type of event that gets him in the arena that is NOT running barrels.
I would bet that even when you get your new saddle that fits better, your issues are still going to be there because his rearing, balking, and fighting you has become a learned behavior and a bad habit. Do not go back to running barrels even when you get your new saddle. Stick with slow work. It may take months, or even longer, but if you don't fix your horse, you're just going to have a fried dangerous horse brain on your hands that is going to seriously hurt you, or someone else.
Horse psychic or not... JUST fixing the saddle is not going to fix your horse, and I agree with everything said here as well! This horse is just overwhelmed, he knows nothing but running! He needs to be brought back and practically started from the ground up.
I have a "fried" barrel horse and it breaks my heart. I am a barrel racer, but will never, ever, ever race him again. Someone, somewhere ran, ran, ran and ran some more if you get my point. Put him away hot, then ran him some more. He never got a break, never knew anything else besides the chute, the arena and the barrels. What did I get a horse, that balks, rears, crow hops and is gate sour beyond belief. If you "shhhh" to him, he flips to another level from a somewhat calm level to through the roof in seconds. A sound some trainers / barrel racers use for cues.
I'm just telling you this to try and help you understand what can happen...NOW though after restarting him, we have our good days and bad. Barrels are no where, we ride outside as much as possible, work by the gates. Some days I can ride no problem out on the trails, arena and some days he reverts and it kills me. He will NEVER be a normal horse EVER again because of what happened. I would never get rid of him, I couldn't risk the chance of someone doing it again and we've grown so much. I'm not selfish though and running him even though he was cleaning up at shows.
SAVE yourself the trouble now and pay attention to what you're doing to your horse. Keep him calm and from getting too hot. It's not an easy thing to fix, if even fixable depending on the horse.
P.S. - YOU were also riding on an ill-fitting saddle, this is painful and can cause LONG TERM damage. This issue is your fault, people should say something and make you realize how wrong this is. ANY horse person that has some knowledge could pick out what's wrong from how you said the horse was acting. Don't need a psychic. Most of the time you go down the list. PAIN is always checked for first in my opinion then you continue on.
We're all just trying to help here, it's a forum you came on and asked opinions. So don't get on US for giving advice and opinions, that's just being rude on your part. We're trying to save you and your horse before someone gets hurt or permanently RUINED.
