Okay, another question from me, while I'm thinking of it.
My horse has a tendency to pick up his right lead, which is no problem when going to the right, but it takes me a few times to get the left lead going to the left. It's hard because a lot of the times if I didn't check I wouldn't notice because it doesn't feel very off. He has always been that way a little bit, but recently it has gotten more noticable, like it's pretty much certain that he'll pick up the right lead at a given time. Why might he be doing this? Am I not setting him up correctly? Could it be a medical/physical thing? It's funny because once he has the left lead he does better actually cantering to the left than to the right. Any ideas here?
