I have a 10 year old hunt pony that has started head flinging really badly. This is an issue he had when I bought him as a 4 year old and it was because he came from some pretty rough cowboy type riders. They used a double twisted wire on his mouth. After a long year of work he stopped his head flinging and was riding nicely in a snaffle. He kind of got thrown out to pasture for about a year and then I started letting some people ride him. One of the riders was pretty heavy handed. I'm not sure she rode him enough to cause an issue like this.
I have the vet coming out on Friday to check/float teeth. I do think it's a possibility because when I was looking at his teeth tonight a couple of them looked pretty sharp. I also think he's trying to avoid the bit because I rode him tonight in a slow twist w/ barely any rein contact (Just a little play here and there to help w/ speed as he was riding very much on the forehand and racey). He kept opening his mouth (I think to avoid the bit) and he was head flinging.
I don't think it's a back soreness issue but like I said, vet coming friday to do floatings on a couple horses so it won't hurt to let them have a look see. I have actually ridden him in a poor fitting saddle before so I don't think my saddles are an issue (he has gained alot of weight though).
I know the easy thing to do would be to slap a port bit in his mouth and roll with it but I want to fix him correctly. We've had to go back to the basics with halts and backs and just four or five strides at the canter to a halt because he's so racey right now and he has just about completely lost his whoa. So we have a lot of work ahead of us but I could really use some advice on the gaping mouth and the head flinging if anyone has any thoughts... I am willing to switch out the bit for something even milder or maybe something with a "play toy" if it really could be the problem. I think some is attitude, some is teeth, and some is that he's gotten away with it for a while.... Just need to fix now....
Thanks in advance.
