After months of intense struggle with canter transitions with my gelding, Digger, I have finally realized it is not that I am a crap rider, he has an actual, physiological issue : (. I was just not able to pick up on something so subtle earlier. He is not "lame" at any gait, but about a week ago, I started to TRY to explain to my trainer that I was losing his hind end through transitions. She detailed what I must be doing wrong, and I began to try try try to fix it by fixing myself and fiddling some MORE with saddle fit. The more I paid attention to it, the more I realized that he could not keep his hind end underneath him through the transition. In fact, to the left, I was getting fakey bend through the front of his body, but he was always swinging his back end to the outside to avoid really using his right hind hock. So I started calling him out on his evasiveness, really keeping my outside leg on him, and keeping my dressage whip in my outside hand and tapping when he started to swing out. My result was squealing and kicking out.
So I started him on an loading dose of Adequan on Saturday, hopefully after a few shots I will notice a difference (the vet told me it would be 4 or 5 shots before I started to see a dramatic change). I am also doing more haunches in at the walk. To the right he is better, and I can get bend to the right at the trot, but he still swings waaay out and collapses on his forehand when I ask for the canter. To the left his bum always fans out to the outside at the trot, though not nearly as noticeable as into the canter. It sucks that he has been uncomfortable for so long and I just couldn't see it. I thought it was an issue with my riding or saddle fit. Hopefully he will get some relief soon. I will keep you guys posted! We are delaying our show ambitions for the moment to try and get him fixed up, this stuff ain't cheap!
