With all jokes aside - much of what was said about the original topic does make sense when I think of how my own son and daughters have all (grown up) matured over the years. I am particularly interested in Handmutter's comment which was, "I do wonder about this - whether the longevity of the particular 'family' of dogs is in any way a factor; does a slow-maturing dog usually live, on average, for more years, or doesn't that make any difference?" That, to me, is an excellent question. I know there are many factors that determine longevity in German Shepherds such as living conditions, feeding, overall health, inherited problems, etc. What I just said, though, doesn't answer Handmutter's question as his question is about whether or not slow-maturing dogs have a longer lifespan.

The maturity rate of canines is related to body size. "Large dogs grow considerably faster and take longer to reach adult weight."(Kirkwood 1985:Favier et al. 2001)
We conclude that large dogs die young mainly because they age quickly.
