Getting a dog to turn on for a new owner...

What I see is this Trent,...dogs have really varied personalities as you know, therefore such things as this are sometimes very hard to understand and 'fix'. I like the idea of hunting her as she's used to,....might do the trick, might not. I also agree that it may take quite awhile for her to return to normal if she ever does. She may actually be a one person/pack dog. I would say give her ample time to get over this strange thing that has happened to her in her eyes. If she's as good as you say, then she's worth spending a great deal of time on.....those dogs don't turn up very often for me, good luck and let us know how it goes, I'd like to know.
