I have recently started part loaning a horse and noticed that he LOTS more flexion in his fetlocks than I’ve witnessed before. The owner says that this has always been the case and is down to his confirmation; same owner for 7 years and old pictures and videos back this up, so it is not something new. His fetlocks aren’t dropped when stood but when working the flexion is beyond anything I’ve witnessed before. I know this can indeed happen during intense activity but this happens to said horse in trot. I am concerned about the pressure this must be causing/ in worst circumstances that it could even be DSLD. There isn’t any swelling/ heat in fetlocks and horse not lame. Any advice please?
