What lifespan range is suggested for Scotch Collies maintaining the lineage of the original farm dog?

Answer

14 to 16 years

The expected longevity for the Scotch Collie, particularly the lineage retaining the robust health of the original farm dog, is often cited in the higher range by specialty or general breed guides. Some reputable sources suggest a lifespan hovering around the 14 to 16-year mark for these dogs. Furthermore, anecdotal reports indicate that some individuals from this hardier lineage have even managed to reach 20 years of age. This higher estimate contrasts with figures associated with the formalized, show-standard Collie, implying that the working background contributes significantly to greater longevity statistics.
