I have 20 year old gelding who is currently being handwalked daily to help rehab a torn inferior check ligament in his rf leg. He also has arthritis in his right hock. When we walk around the arena with his bad legs on the inside he balks, bends to the outside with his neck, tries to stop and generally looks a bit grumpy as we pass the arena gate. When we go the other way around the arena he slows down a bit as we pass the gate but he doesn't stop or misbehave like he does the other way. I am trying to decide how much of his behavior is him being a brat (which is definetely some of it) and how much is because he is in more pain going to the right. Anyone have any experience with something like this?
