Horse bucks on trails
Okay so I'm helping my instructor bring this horse back into work, but he has an issue with trails.
Bailey is close to 20 thoroughbred gelding. He has competed in eventing up to
Novice level. Last year he broke his patella (kneecap), was on stall rest for 4 months, almost had to be put down. Vet didn't think he would ever be desirable again. He's back to full flat work! (Yay!) However we've been trying to do some trail work. To do hill work and get him out. On the trails he's fine at the walk, but when we trot he bucks. He bucked me off today in the apple orchards. I got back on and we trotted a 20 meter circle and then walked for the rest of the trail. I tried trotting again in the same spot on the way back, but he bucked again. I didn't fall off, I had him trot a couple steps, so I brought him back to walk before he could do anything. Once we got back to the barn I trotted and cantered Bailey in the ring.
My instructor warned me that he's not good on the trails. Bailey is really obedient
In the ring. He was really bad and bucked all the time when he was younger, now he only bucks in the indoor or on trails.
What do you think I should do? Should I just not do trails? What should I have done differently?
I'm the only one riding him really. I ride him 3-4 days per week in the ring. I just want him to be calm and well mannered on trails.
(I'm sorry for my grammar errors. Mobile is not being nice to me.)
