Anyone ever experience this problem while riding?
So my mare has this awful habit of throwing her head while riding. I mean not like a tiny throw its a constant head throwing until i finally work it out of her for a bit, and then she will start up again after a while. We have checked all of her tack and there is nothing pinching her or causing discomfort. She is completely sound, no lameness issues ever. We have tried stopping to let her get an inch on her head or leg, and we have tried cleaning her hooves out to see if that was what was bothering her. I have also tried a range of tack, from a different western saddle, and different english saddles and pads in both. She still does it. We've also been trying to pull her head to the outside whenever she throws her head, but she still keeps it up. We also tried working her harder when she did it.
Last thing I tried was changing up the routine from just doing flat work to adding in our barrel patterns or a few jumps. She still throws her head. I do not think its an excitement issue either cause shes a very lazy horse for being only 7.
Any ideas of what anyone has tried? Im desperate now!
