I finally got my mare in the horse trailer!!! I moved the trailer over in the pasture, and backed it up to one of the tiers, so there would be no stepping up. She wouldn't lead in, she would walk up to it. So I turned her around and backed her in! Lol It worked. Did that a couple times. Then I faced her forward, put a butt rope on her, and finally got her eased in face first. Let her eat some grain, backed her out, led her around, put her in again. Still had to use the butt rope, and a shoulder in her arse, but she went in much easier!!
I let her finish her grain, backed her out, and let her loose. Of course, it was dark by this time. Tomorrow, more of the same! Tried the "natural horsemanship" way, didn't phase her a bit! Hopefully tomorrow will be easier!
