I really feel so bad for you. My niece boards at a barn where the BO's daughter treats her like crap, too. The BO has bought his daughter about 5 horses, and she doesn't even take care of them half the time---leaves their stalls filthy, and even on the Saturdays I've been there, she is nowhere around---I gues shopping with her friends is more important. She acts like my niece is beneath her, but my niece cleans about ten stalls a day in exchange for board, and she also has a job! I wish my niece didn't have to put up with this either, but at least the BO is nice to her. I wish you all the luck in the world in finding another barn---don't give up! There are a lot of good people out there. I'm just glad I'm able to keep my horses at home. Again, good luck, and keep us posted.
Everything can be achieved through patience!
I'd rather have a problem horse than a problem man. The horse I can work with. The man---I cannot help!
