I just got this new barrel horse about two months ago. He is very relaxed in my arena at home and has never offered to buck. However, he frequently tilts his head back and forth at the lope and occasionally drops it. I had used him as a back up barrel horse a few times that my horse came up lame at races, and had never noticed this issue before. His last rider was new to barrel racing and pulled on his head a lot, where I have very soft hands. I have never experienced an issue like this, so my first reaction was to try different bits, but he continually has the same issue no matter what I put in his mouth. I thought he may be out at the poll, so my chiropractor is coming out sometime in the near future. I was wondering if anybody else had any more ideas???
