Although it was sprinkling, I decided to see what I could do with Libby in the round pen; I really didn't expect things to go very well, but I decided to follow the old adage, "Do something, lest ye do nothing".
I read a couple of articles on the Internet several times over. One by Julie Goodnight, a very helpful one HERE, and some others.
Once my filly and I were in the round pen, I began swinging a rope in Libby's direction, pointing in the direction I wanted her to go (telling myself, "Yeah, sure... she's going to know what I mean when I point.") and after a couple of false starts and wrong tries, she was soon going around and around... just like she was supposed to do!
And by about the third time of me dropping my pointing arm and my rope and saying whoa, she realized she was supposed to stop. After another round or two, she not only stopped at my signal, but she turned toward me, paused, and then slowly approached me to get her praise for a job well done.
I only took her in one direction today. It began raining harder, and besides, I like to end things on a positive note.
What a horse.
