Researchers at the Gerald P. Murphy Cancer Foundation have found that Rottweilers who were not spayed until after the age of 6 were four times more likely to live an exceptionally longer life than Rottweilers who were spayed young.

We found that female rottweilers that kept their ovaries for at least six years were four times more likely to reach exceptional longevity compared to females who had the shortest lifetime ovary exposure.”
