I don't notice his off side as much while trotting. He can be a bit choppy at first, but after being fully warmed up, I don't feel a difference.
He's checked daily for tenderness and any health issues, so that isn't the cause. I'm thinking it's probably because the cold and snowy weather keeps me from exercising him as much.
What are some exercises I can do that will help strengthen that side? I've been doing circles and serpentines, but I'm not seeing a difference.
