I just got a OTTB and I just want to know how to start her. The lady I got her from basically did nothing with her, and she is so sweet. She is 9 and hasn't been ridden since the track. I tried lunging her and she has no idea what to do. I put my 13 year old on her back for a few seconds and her bottom lip just flutters. I read somewhere that is stress. What are some things I can do with her to make her comfortable and not think she needs to race. I want to start her slow and just want some tips on things I can do with her. Thanks
