Unforunately I don't have access to a round pen. I wish I did. I've tried in the arena, but the arena's just too huge. There is a smaller square paddock on the side of the barn, but it is attached, and there are open stalls without doors that I can't block off, and she goes in there and stays there.

Fly allergies are just horrible, I felt bad for her. I stayed pretty diligent about the fly mask and sheet, but sometimes the lady I board with forgot to put it on. It didn't help too much anyways. I think the holes are too big on the sheet. I had a fly "collar' on her, that seemed to help her face, but they just bit her on her body instead. I tried cortisone shots and stuff but it didn't help much.
