Prison break not going as planned

Cheyenne had found a weak point in the fence earlier and escaped from the dog yard. She then escaped twice more before I was able to fix the weak point. Now she is determined that the weakness has to be there still. For over an hour the little dog has been running back and forth along that side of the yard jumping at the fence trying to get it to fall over again. She's starting to get frustrated by the lack of progress on her newest escape efforts.
