Here is my gelding's (shadirr) back story. Shadirr was used for therapeutic trail rides for a majority of his life. The woman I got him from took her daughter to his facility and rode him multiple times, he was great. Well about 4 years ago shadirr had an accident on the trail. The details are fuzzy, but apparently it was a mother and son who rode out alone and came back with a hurt shadirr. The son said something about a fence, and they left quickly without explaining what happened.
Well the woman I got him from bought shadirr from the facility and rehabbed him extensively. He had some back problems, but nothing severe. She had massage thereapy for him and work very closely with a vet for him recovery. After some time he was cleared for riding. He was good for her, but she would stop anytime he threw his head; she took it as he was in pain.
So here's where I am with him. This Guy has amazing ground manners. He is so willing to do what I ask, no problems or vices, stands great to be saddled and mounted. But once you ask to go forward, he gets angry and backs up. He will spin in circles if asked, any direction but forward. I have had two trainers out to work with him. The first knew nothing about horses and was quickly relieved of her duty. The second was a great trainer, but jumped off him when he kept backing up. She did this everytime and did nothing to correct him.
My question is what can I do? I feel that if I knew some new techniques I could fix this myself. He has never offered to Buck or rear, and gives his respect great on the ground. Any tips or excercises I can try would be greatly appreciated. Once again it is not a medical reason, I've had my own vet also clear him for riding.
