This problem has came up 4 times now. It is 100% a fear issue. To be clear, I never reprimand a frightened animal. The problem is my little girl loses her mind if the saddle slips. I'm not one to over dramatize things. But I have a feeling someone beat her for it. The look in her eyes when it happens is terror. I want to do whatever I can to help her over her fear. I am able to calm her down and I am making extra sure the girth is tight before riding. But I would like to stop the outburst. The latest incident was me hand walking her back from the valley. I was stupid and loosened the girth on the walk back. She saw something move in the field and jumped sideways. Then the saddle slipped and all hell broke loose. I was able to keep her in a circle around me. She settled down quickly and walked back like nothing happened. But the look in her eyes really got to me. So I am looking for gentle methods (for the ground) so I can slowly work her through it.
