Greg, I've seen Berners with white markings all the way up past the elbows, and others with no white on their legs at all. So markings won't really tell you much one way or another. You'll know a good deal more as Pippy grows, any idea just how old she might be?
Pippy is a very lucky girl - bless you for finding room in your heart and your home for a shelter girl! She's obviously attracted a very nice human, which makes her a Berner in my book! Pat Long (& Luther) Berwyn PA
