For a little back ground info: I have had my mare at my parent's house until about three weeks ago. She was never penned with any other horses except for the greetings from the Stallion that my dad owns. Now she is penned with two other mares (10 year old and a 2 year old).
I the only time that I have seen this problem from her (in the 10 months that I have owned her) is when I rode her by myself 1 week ago. I really don't want to encourage her to keep this up. I need to try to break this habit that she has developed. The reason for all this is that she stopped listening to me and started to lead her own way which she almost caused use to fall into a deep hole. I have tried to gather her attention by doing circles and getting her to focus on me. However she still refused.
I purchased this mare broke and have found that she is trained very well and has continued to impress me. She will lunge, neck rein, back, stand quietly, stand without being tied for a long time, loads in the trailer without being led into it, and etc.
I really need some help with this.
