Check out this article from du Coeur BMD's web site:
Our first Bernese Mountain Dog was Manda. What follows is her story. We originally wrote this to introduce ourselves to the berner-l (an online community of Berner lovers) in early 1995. It is a long post, I’ve divided it into 4 parts.
I know this is hard to read online, but it is a story that anyone considering buying a Berner should read.
