Which breed of "large" dog lives the longest.

Large as in labrador, collie, shepherd, etc.

I was doing some research on this question.

I did find an interesting website that provides general information regarding size/breed and gender relationships to longevity.

Life Expectancy/breed/size

The Doberman can live from 15 to 20 years as a large breed dog.

The Anatolian Shepherd Dog and Black Russian Terrier can live 11-14 years.

The Briard can live 14-16 years.

The Bullmastiff can live 15 years.

Thanks for the info and the link.

edit addition: Any thoughts on when we are going to genetically engineer dog to live longer to be a true life long companion of Man?
