I fear that this OP has not heard what she wanted to hear. I would guess she wanted a magic instant fix for this problem. Anyway, she has not visited since the first 3 or 4 responses went up. I hope she comes to terms with her problem so she does not get hurt. I hope she comes back. She can learn a lot from the experienced people here.
Situations like this makes you just want to give a piece of your mind to the person that talked her into getting such a green horse. A seller's greatest responsibility is to match and fit horses to the right buyer. Boy, was this a miss-match.
