So my horse and I have been doing barrels for about year. My horse has been trained for a veryyyy lonnggg timee. She was amazing last summer but all of a sudden after we haven't done barrels in a couple weeks; she has been acting up. When we sprint towards the first barrel, she gets up by the barrel, doesn't rate and fights the bit. We have a wonder gag bit and we've used it on her ever since we got her which is about a year ago. I would like to know of some drills, bit change, anything. I know it isn't her teeth because we got them checked and filed not too long ago like two weeks ago.
I agree, I'd get something else and get her to rate back to you better.
Just see about going slow for now and fix that problem. Emphasize the rate. Run to the first barrel but then rate rate RATE back to a slow lope for the turn, maybe circle it a couple times, and finish close and make him add speed again between the first and second barrel. Also set him in the ground a couple times at your rate point, stop and back up in your tracks, then trot up and circle the barrel a couple times again.
