Until they got lunch.
My pony also thinks trail rides are an all you can eat buffet. When I need to get something out of the tack room and she's in her halter and lead rope I just drop the rope and go get it and she starts mowing the grass right outside the tack room door.
If she can't find anything to eat she'll dig up roots to eat, or eat dead leaves. I'm just glad I work her hard so she doesn't eat herself into foundering. She'll eat anything I have, even french fries and cheese-its. I'm pretty sure she could demolish a round bale on her own in a week... Along with her horse-sized meals.
