In general, I try to keep my program very consistent for my horses, so there aren't any major changes between home and the shows. The biggest difference for my horses is turnout. At home, they turn out in the field every day, but at the shows, this is obviously not possible. So instead, we handwalk and graze as much as we can. I don't like them to be stuck in their stalls all day. I think it's important for them to get outside, stretch, get some fresh air, and just be horses.
Thanks for your question!
