Thanks for all the comments. :) Ok so... I asked my friend how she got in the trailer when she was coming home from the breeders, she said that she was not there. The stallion owner brought her home. Hmmm... The stallion owner said she jumped in the trailer as well..... Im wondering if something went wrong that time and my friend did not get told. ??? So... so far I have tried feeding her out of the trailer, by putting her food right at the edge of it. I have tried the treat reward and of course lots and lots of praise. I have sat at the edge of the trailer and just sat there for a good hour to get her to relax around it. Here is what she does..... I will bring her up to the trailer as nothing was wrong and just go right to loading her, she will put her front feet in and then blow back out. She will do this for ever and then she will just plant her feet and not move or just pull you as far back as she can away from the trailer. I tried every time she put her front feet in to feed her a treat and let her relax with her front feet in there, but she just grabs the treat and backs out as fast as she can. Some times its like she is just being a brat. No she is not in foal now. She lost her baby premature.
