So, my 8 year old OTTB gelding has been doing fantastic. I've had him over one year now and we just competed in our 6th show. We are adult equitation champions in our region, and he's jumping crossrail courses very well. It's been a terrific year, with a few setbacks.
In our last show he picked up the wrong lead in our flat class. It took me five tries to get it. That has never happened. I decided it was a "one off" and figured pilot error and being so hot. Then yesterday in our lesson he once again refused to pick up his right lead! My trainer got on him and worked with him a bit and eventually got it, but it took work. Its like he suddenly forgot the leg aid. What I do at the walk is make light contact, keep my inside leg at the girth, and use my outside leg behind the girth to signal him forward. For months that has been working 98% of the time.
His saddle fits, no lameness, teeth were checked. My trainer thinks he is just being stubborn. She also said that since his left lead was the challenging one initially, I may have over-drilled it and now he is confused.
Can someone recommend the best way to regroup on this? Any advice on why it might be happening?
