He doesn't swish his tail or refuse to canter. I don't ride with a saddle and I haven't for a good three or four weeks so it's not saddle pain. It may be left over pain, I'll check his back. He will pivot his hindquarters and forequarters with ease, back, side pass, walk and trot and all that as usual. This past week or so he has made it his gait of choice. The crappy thing is his trot stinks as it is, he's basically pacing when he trots and his canter is okay as long as we are in the arena but out on the trails, as we usually are, he gets excited and his canter gets sloppy, so together they're like a train wreck.
He trots like this horse does, he doesn't know what slow means. http://www.youtube.com/watch?v=fH8KZVhKBLI
