I just saw this quote since the thread has been bumped up. From your tone I’m guessing that’s you in the video. Why should it be necessary for me to ride your horse and show him correct contact? Taking lessons with a good trainer is key. And you know, even when riding for a vet eval, different levels of contact should be used so the vet team can watch how the horse goes on a long rein, on correct contact and collected to extended.
I hope your horse is doing better too. It is great the OP found the solution for her horse.
