So, I have to start from scratch. Right now, I'm working on gaining her trust and establishing that I am not intimidated or afraid of her.
One thing that I have noticed is that with any spoiled brat, she lacks patience. She gets irritated easily and then that is when she acts up. I don't try to push her, so she doesn't have the opportunity to act up.
In the last few days, We can lead, stop, and back with the halter and lead. I've made a rule that she is NOT to be hand fed. I'm hoping that will cut down on her being mouthy. I'm confident that in the coming months, we'll progress nicely.
Her given name is Spirit, and since it's bad luck to change it, I've just been calling her "Pretty Girl". She's a very vocal horse, and responds well to verbal praise.
