I have had my off the track TB snce April. He is 17.1 hh an dis 6 yrs. Bought him from a man who purchased hm off the track from the breeder. The man I bought him from did not do much training except for ground work. I have been working him more and plan on a jumping career with him. I have a trainer but this is my first horse and my first time trying to train a horse. He is a very willing and smart horse. My problem is that I can ride him in a round pen just fine. He walks, trots, canters, stops, backs up and is getting contact with the bit. The other day I decided he was ready to go in the arena and ride. I lunged him first and he was just fine. BTW I have free jumped him to 2' but he kept kocking down 18". I put down trot poles and got on to ride. This is where the problem started. He became very anxious and wanted to take off, I stayed calm and relaxed but he started backing up hard. I pushed him into a working trot trying not to mess with his mouth too much but he still wasn't listening. So I tried taking him over the poles to redirect his mind but it seemed to agitate him more so I asked him to walk an d he took off in a full gallop. I tried everything I learned to calm him down, I didnt pull on the reins, I didn't get tense but he tried to jump the two sets of ground poles and then saw the arena fence which is almost 5' high and there was no stopping him. His neck was tense so I was unable to turn him and he jumped the fence but caught his back legs and flipped over the rail throwing me off. HE is perfectly FINE. I had the vet check him, me on the other hand have broken my left forearm. I am trying to see if anyone has any suggestions as to why and how to fix the problem.
No I will not get rid of him I bought him knowing the dangers and challenges and am willing to work with him. He is a great horse I just need some good advice.
