The other day I tried lunging one of the mares and was dissapointed when she sat at the edge of the round pen and grazed the whole time, ignoring me while I asked her to move forward and occasionally turning her head and pinning her ears at me as if to say "back off!". I tried for quite a while to get her to walk around, and eventually got her to jog half a lap, which ended in her cutting halfway through the ring, walking to the gate, and grazing on whatever was growing on the other side of the pen. I made a mistake by not getting what I wanted with her before I put her out, but I did not want to refer to yelling and hitting, and I did not know any other ways to make her respect me. Does anyone have any ideas on getting this horse to listen to me? I've never really had this problem before and I don't know how to handle it.
