I have a 12 year old paint gelding I've had since he was 5. We were both beginning barrel racers then, so as we both learned new things, I also inadvertently taught him some bad habits. He tends to favor his left lead, and as such dives into his second and third turns. I've done tons of slow work, pushing him past it, wider pockets, not even turning the barrel, etc. The problem is that he doesn't anticipate them in slow work, only when running. I'm not sure how to fix this issue. Any thoughts are appreciated!
