I'm training a young mare. She is very docile and lives in a herd. She is very low ranked and get's pushed aside a lot. She had very little trust in humans when I started working with her from the ground up. I am now riding her and she's doing splendid. However, last week I went riding with a friend. She asked me if I would show her how to do something on her horse and I said I would. I dismounted and I handed her my horse's reins and I mounted her's. As I trotted away my horse took a fit and started whinnying and went into a panic. My friend had a hard time to hold onto her and settle her down. My horse isn't herd bound at all, and doesn't even really know her horse that well because they are quite far away in seperate paddocks. I also have no problems hacking alone with her.
She is extremely attached to me and will run to the fence as soon as she sees me. I am the only one riding and working her because the owner is busy with other things right now. I tried to get my friend to brush her and work with her, and the horse is fine as long as I'm by her. But, as soon as I leave she panics and wants to follow me. It's almost like she's acting like she's MY foal XD
Any suggestions how to build her confidence so that she won't freak out of I leave her with someone else? If I'm not at the barn she is fine to be handled by her owner, but if I am, she wants me by her side constantly. I've never encountered this problem before. What's the best way to wean her off ME
