I have a ccouple ideas to bond you and your horse.
- take her and a couple other horses out into a round pen, and leave them their to eat (grass, not her actual feed). Go in and just walk with them, don't touch them. After you've ben walkin for about ten minutes, go up to her and make her step over just once. try doing this to a couple other horse, then continue walking around. then push them over again, then walk, then leave. This is actually what a leader of a herd does.
-take her into a round pen again, and get her walking around the edges, trotting if you can.. then stop. face her, but back up a little, she'll start to come to you, to inspect you. if she doesn't get her walking again, and then try again, slowly back up from her. This is a great bonding exercise.
Hope I helped. Good luck!!!!
