alas no. We always have German Shepherds. This breed usually has trouble going beyond 10 Jears. 12 is rare and the oldest one we ever had was 14.
They tend to age rapidly once they passed the 8 year mark and then develop cancer, serious heart conditions or arthrosis. As far as I remember none of our dogs died of old age but every single one had to be put to sleep for medical reasons.
As a general rule mixes between different breeds are much healthier and longer lived than pure-bred ones. Often more intelligent, too.
