A mutt could still be the offspring of two pure bred dogs and have inherited genetic problems from both.

Mutts may often be better than their purebred parents (by various objective and subjective criteria), but in the end it'll take a few generations of mutts and, well, survival of the fittest before you can see a general trend towards improvements in health and longevity. Genetics are a lottery, starting with unhealthy parents the odds are against the offspring. It'll take generations for the population as a whole to move towards being healthier on average.
