Hello, I'm working with someone's horse at the moment that has a tendency to 'bunny hop' at the trot and am trying to figure out If it"s behavioral or pain related. The Vet and farrier are involved on a consistent basis and so far have found nothing. The horse also gets chiropractor work done regularly and the saddle has been checked and fitted. He has thrown some rather large bucks with other riders, but it has only been small little bunny hops with me. I've worked with horses that bucked over the years and I prefer to look at all angles before I attempt to ride through them. The horse previously was used as a hubby/trail horse and occasionally as stud, then was gelded late. He came with an ill fitting saddle, but that has since been fixed. That was quite a while ago, now. When he first came, he was quite pushy, but after about a year of groundwork he is MUCH better and respectful of everyones personal space. I just started riding him consistently this year and others were riding him on trail rides the year before. He's had a little arena work, but mostly at the walk because he is still very green. Last year, he did buck someone off on a trail ride, but I wasn't there so I'm not sure exactly what happened. I heard they got back on, but I also thought I heard that they didn't get back on immediately and walked him back in the trail to find a spot to get back on. I'm thinking he may have clicked buck=get rider off. He is generally a calm horse, but every so often he does seem to test his rider. He is excellent at the walk and just learning how to relax over the back and into the bit, but as soon as you attempt to trot he tries to buck. He spent most of his life inverted like a giraffe and has alot of belly, so for now, my aim is just to get him consistent on the bit at the walk, relaxed over the back, and add a few trot steps in at a time. Sometimes he will pick up the trot himself and he never bucks in that instance. He does however bunny hop when asked to trot. While lunging, he does not buck at the trot, but will at the canter. The owner has said he can get a little rowdy on the lungeline, but he has only ever tried that once with me and now he has been quite good. Currently he is on bute for a week to see if there are any changes. He still bucks at the canter on the lungeline. I've been thinking that this may possibly be due to weak stifles since he is out of shape and it could also be a learned behavior. Has anyone had a horse like this and figured out why they were bucking? I just find it strange because he isn't a reactive horse, doesn't seem frustrated, and doesn't seem uncomfortable.
