This is going to be kind of long so I apologize in advance and I appreciate anybody who takes the time to read and respond. I have owned this horse for 5yrs, he has always been cold backed but 2mins on the lunge and he’s good to go. Left lead canter has never been his strong suit but 3yrs ago I had him going great. Then I met a guy, pretty much stopped riding regularly, maybe once every few months tops. In November 2018 he started swapping off behind at the canter. He’s roughly 15 now so I figured he was due for some maintenance. I don’t jump anymore so he is used for mainly light hacking a few times a week when in regular work. Not a heavy load by any means. Saddle fitter came out and reflocked since he had been out of work so long. The had the chiropractor out who is also a vet. She adjusted him and did some acupuncture and said he could be hock sore. Didn’t really light up anywhere else. This problem got progressively worse over the next few months then in March 2019 his right rear sustained some sort of injury low like a large wind puff. Vet ultrasounded the area and said “maybe” saw a defect in the medial sesamoid ligament but couldn’t say it was new or old, so basically inconclusive. During that same exam we started to do flexions and blocks and found he was like 3/5 on upper limb flexions so we just quit and decided to revisit this another time. This is not a horse I am going to spend the money to MRI as I’m not in the position to do so. So I just gave him time off.
Mid to late 2019 I had the chiro come back out and do 5 rounds of acupuncture before I injected anything but he was still NQR. Late 2019 vet came out and did hocks, then the next month SI, then finally stifles. That did not fix the problem. He will canter in the roundpen without a rider but absolutely refuses to do it if I’m on his back. I should add since all of this vet work I have ridden sporadically at best. Once he started to act out I laid off of him big time because I don’t believe in forcing a horse who is trying to tell me something to keep working but I really am at a loss of what else to do. I will attach a short trot clip from Friday to this post but it’s hard to get anybody to video me at my current barn. I am open to any and all suggestions!

Edited to add my regular vet wants to believe it’s his back but neither can ever illicit a pain response when working on him. Also the problem started with not picking the left lead then eventually evolved to refusing the right lead as well
