So my TBxWarmblood gelding has been a great boy up until about four days ago. Last Friday we were working in a large field when I noticed that at a canter he seemed to be stumbling a lot, especially when we turn at all. Big circles, small circles, just turning the corner of the field, etc. I thought it might just be an off day and let him hang in the stall overnight. I came back on Saturday and he was doing it even worse. It was almost like he was losing balance in his hind end. I got off and checked saddle, tack, and feet for stones. I lunged him to see what was happening...and he is doing this weird thing with his back legs almost like a bunny hop! Like instead of one hind leg hitting and then another, both are hitting and pushing off at the same time.
Anyone ever seen their horse do this? Know what causes it? It has never been a problem before.
Also, any thoughts on if equine chiropractors are a quack or a good idea?
