Just to let all you new List members know, there are a number of articles about health issues: http://www.jersey.net/~mountaindog/berner1/
The articles explain the health issue, then compile a number of experiences shared by members of the Berner-L. There is also a copy of the article on Histiocytosis on the site, my goal is to be able to remove it someday in the future. A huge thanks to all of the people who were willing to share for all the articles, but particularly the ones for histio - I know how painful those were to write. Pat Long (& Luther) Berwyn PA
