Back story - 4 (almost 5) year old Trak/Thoroughbred who given to me by a friend. He lived in a field until late 3 year old, then was taken out to be broke. He was backed by my friend but they had a few bad rides and she pretty much had enough with him. He bucked her off once, and another time went to buck, she pulled his head up and he hit her in the head, then panicked and fell over.
I got him October last year, and quickly realized he was not ready to be ridden. I did a tonne of ground work with him, ground driving, lungeing etc. He did very well all this and was a lot more relaxed and trusting to be around. I started riding him again in late January and things were going pretty well. I took a few weeks off working with him due to time restrictions and when I went back to riding him he developed this new thing.
Once I mount, he wonāt go forward. He is trained to go off the leg, he knows what leg on means, he knows how to move sideways away from my leg. I usually sit and wait a few minutes, or try and turn him on a circle. I have not used a whip as I worry he will either bolt or buck as he is quite sensitive. When I finally do get him moving he threatens to buck, kicks out, etc then stops and wonāt move again.
I can usually get him going but it takes me anywhere from 20- 30 minutes to get the ball rolling. In the first few minutes when he is moving he tries everything to not do work. Buck, kick out, bolt, stop. Once we DO get going, he goes along quite nicely!.. I have tried several different saddles, all with the same behavior. He is absolutely an angel on the lunge, and very good when we do get moving so I am not thinking it is pain related. He was (not anymore) a bit tense when saddled and would sometimes hop after asking to walk forward.
I have ridden some very difficult horses in my life but I have never experienced a horse quite like this. The more consistently I work him the better it gets, but if we take even one day off we start all over again. Anyone with similar experience?
Advice?
