Chesapeake Bay Retriever Life Expectancy The good news is that Chesapeake Bay Retrievers have a relatively long lifespan for a large dog. These robust dogs can live for between 10 and 13 years.

While the Chihuahua may be the king of small dogs, it's also a longevity star. With a life expectancy that can easily exceed 14 to 16 years, some even reach 20 years!
