As far as I can remember Bruna
http://www.wolfdog.org/dbase/d/879
got 17, I saw her with 16 she was still in pretty good condition though she didn´t live very comfortable. Her daughter Esta got 18 and something.
Tabury z Rosikova was put down with 15 because his owners didn´t want to let him outside in the winter with -20 degrees any longer, not out of a real health emergency situation.
His daughter Gerda z Rofa is in extremly good shape for her 12 years and 3 month without any medication or medical support, We hope she will live many further years.
Eda
http://www.wolfdog.org/dbase/d/1142 was shown in Veteran Class with 14 years in astonishing good condition, I can´t remember how much longer she lived but I think about 2 years.
But I don´t know any
living CSWs much older, Milo Ruskov dvor is likely to get 14 and older but you never know in this age.
