I think the OP is worried about having wire in a small area. Of course, the smaller the area for the horse the more wear and tear on the fencing and the more the horses are going to be testing the fence. I personally wouldn't want to use wire fencing in a small dry lot for that reason, but I wouldn't mind it in a big pasture.
