What is the normal lifespan of a Rottweiler?

In general, longevity within a species follows a pattern.  Smaller animals of the same species usually live longer than larger animals of the same species. Smaller breeds of horses tend to outlive larger ones. Dwarf mice live longer than standard mice.

The canine species mirrors the rest of the animal kingdom with smaller breeds like Chihuahuas and Toy Poodles usually living 14 to 16 years. Larger breeds like the Great Dane and Saint Bernard do well to reach eight to nine years. Following this pattern a Rottweiler would be expected to have a life span of between nine to ten years.
