So my now four year old gelding that I have had since he was just a yearling and has been extremely easy to train has now decided that he just doesn't want to lope. I have lunged him with a saddle and he will lope but when I am
On him he will either buck or he will completely refuse to canter and just do an extended trot. He is easy to ride at a walk and trot he is a bit on the lazy side but he has always been willing to please. I have loped on him a few times but it is always short lived . All of his tack fits fine and he is not bucking because of an ill fitting saddle because I have ridden him bare back with the same results. I have had his back looked at and he is in great health. What steps should I take to get him to canter without it being such a battle because my back can't take much more of this getting bucked off.
