Hello all!! I have owned my TWH now for almost 8 months. He was spooky and over reactive when I got him in January. I did a LOT of ground work with him and a LOT of walking when I first started riding him. He was broke to ride, but untrusting. He is 7 yrs old and he was super smooth. Since I have been asking for the canter, though, he gets kinda nervous/anxious. I think he tries to pace or trot, not sure which, but it is really rough and hurts my back. I bring him back down and let him relax and we try again. On the trail he does better then in the arena, I don't know if he has more room out in the open and that is why?? He will canter in the round pen when asked, and when he does break into the canter in the arena, it's only a few strides and he goes into that rough gait again. I have heard that TWH have a smooth rocking horse canter... how do I get that without loosing his smooth running walk?? Is it possible? Advice please, this is my first time training walker, thank you!!
