I am new here and any advice is greatly appreciated. In Sept I got Harley a 7 y.o. Quarter horse and he is ALMOST perfect. He has one major flaw that I can't stand. He throws his head. It starts when you go to cinch up the saddle. As soon as you tighten the cinch his head goes up. People have noticed it and laughed about it. Out on the trail he will be just fine for a while and then he starts throwing his head again. That is when he starts to stumble. I am afraid that he is going to do one of two things with this ... (A) knock some of my teeth out with his big ole head (mane has brushed my nose on more than one occasion) or (B) start throwing his head while we are on some rough trail and stumble and fall and hurt him, me, or both of us. He has been checked by the vet, and chiropractor and there is nothing structurally wrong with him. I am useing a tom thumb snaffle on him which is what he has used all of his life. I have also ridden him with a tie down (bungie type) and he goes right through it just like it isnt there. Any other ideas?? All help is appreciated.
