I didn't really think about the crate issue with her being a mill pup. I'm sure there are some special issues there with those dogs as you have pointed out. Maybe just make some area hers with a blanket that is always her spot and it's her choice to leave or stay there, etc. Sounds like you are getting some good ideas from the other board too. I hope she starts realizing she's in a good place and has no need to defend herself or her spot. She was probably never really allowed to develop any social skills with other dogs or people. I, too, am very fascinated by dog behavior and psychology
