Background
Older, upper level trained PRE (screen name is the horse in question) who decided earlier this year that he only has a left lead canter undersaddle. He will happily do a countercanter to the right undersaddle. In hand, lunge line and in long lines, he has no problem with the right lead, and very interesting is that if he picks up in the incorrect lead inhand can be queued for a flying change to the correct lead. Given that this horse is a bit older, I did do a thorough vet exam earlier this year and no unsoundness/physical reason was found. I have also used 2 different body workers who havent found any physical reason for the unwillingness to canter on the right lead. I have tried different saddles, shoes on and off behind and have continued with regular body work. Issue happens with both me and my trainer.
Any ideas? I really dont want to think that the right lead is gone forever…
