don't really know why...could have been the previous owner over trained her in the pen.
could be you are leaving her in the pen too long or maybe you are baying her too often... Cut her back to once a week and only for about 5 minutes at a time and praise her good when she does well...
to me a few times here and there is best and for short periods of time. This will keep her interested and her mind on hog.
Then every once in a while a 20 minute bay might be good so she can learn how to work and stop a hog...If she needs help to do this then have another bay dog help her.
