By jove, I think she's got it!

I don't know who is smarter - me or Nina! LOL I finally figured out how to get her to consistently "do her duty" outside. We go outside and I walk her to the far side of the yard. I don't have a huge yard, but it is a far enough distance to Nina that once she takes that hike that she is ready to squat. Sweet success! I have learned not to praise her until she's done because if I do she tries to walk over to me and continue to "do her duty" at the same time. Kinda comical to watch! She is such a very sweet girl! I thought Sammie and her would become a dynamic Chi team, but Sammie is much too busy wrestling with Lucy and Nina wants no part of those wrestling matches! As she becomes more comfortable here, she seems to be quite independent and knows her mind. She will roam the yard without me, but when she wants some lovin' she will be right back at my side.
