As far as we know, no. According to the American Kennel Club, the average lifespan of a purebred Rottweiler averages between 8 and 10 years. Meanwhile, mixed-breed dogs tend to live closer to 12 years. But keep in mind that these numbers only apply to purebred Rottweilers. There are many different types of Rottweiler mixes, and these lifespans vary widely from breed to breed.
