As an adult, I've had 4 pure bred Collie's. Our female Tri passed at 8.5 yrs old; our male sable passed at 9.2 yrs; our blue merle female just passed at 11yrs. We still have 1 female sable (she was siblings with our only male that passed @9.2 yrs) and she will be 12 yrs old on 7.4.12. As a kid, my family always had collies & none made it past 9-10 yrs old.
I personally think dogs of all breeds are being overbred & that leads to a shorter life span. We spare no expense on their food, care, medical, etc.
