He was not broke by me at all and has never had a stop. But im not saying he doesnt have one at all he does it just takes him a while. Just saying.
In my opinion, a horse that does not stop instantly
when I ask them is downright dangerous. No matter what you are doing. For the safety of myself, and the safety of the horse, that stop needs to be foolproof in any situation at any speed.
It doesn't matter if you didn't "train" the horse in the beginning, because you are training him now, because you are his rider. Cherie started an excellent post on this; I suggest you read it: Every rider IS a trainer -- every time you interact with a horse
Training a horse for barrels that doesn't even stop in the first place is a huge mistake. You can't control him enough to stop him; does it seem like a good idea to teach him to RUN around three barrels without a stop? No, it's not.
If you read that barrel sticky I posted, there's quite a few posts that go into detail about what your horse should know (and what the rider should know) BEFORE you start training them for barrels. A horse that stops on command is at the top of that list.
--stop softly and immediately from any speed
--walk, trot, and lope on a loose rein, and relaxed
--back up freely when asked
--give to the bit in any direction, and break at the poll
--neck rein and direct rein
--be able to sidepass and two-track
--can execute a turn on the fore, or a turn on the haunches
--simple lead changes for sure, and helpful if knows flying lead changes
--can perform “perfect circles” with little help from the rider
--be able to move any part of the body (hip, ribcage, shoulders, head) at any speed at any time
These are the things your horse should be able to do, just from good ol' training. If not, then they won't have the control you need to make a barrel run. Your horse:
--does not stop
--possibly doesn't travel nicely on a loose rein
--if he doesn't stop, he might not like to back up
--he certainly doesn't give to the bit, because you jerk on him (so he just braces against you instead)
--he's not soft in the bridle, so direct reining won't be good. He doesn't know what your legs mean (because you kick him hard, instead of cueing him gently) so he probably doesn't neck rein well either.
--Etc Etc Etc
Main point --> Work on getting your horse more broke and your barrels will improve automatically. And yes, it is your responsibility to get him more broke because he is your horse and you are the one riding him.
And again, this is why it would be so beneficial to find a trainer to help you. It doesn't even have to be a barrel trainer. Even a dressage coach, or a reining trainer, would help immensely to soften your horse and teach you how to cue him.
Note that it is going to take MONTHS to reverse his bad habits, because it's been going on for the full 3 years you have had him. You didn't give him bad habits overnight, so it is not going to be magically fixed overnight.
