One of the hardest things about being a pet parent is having to say goodbye to our much-loved furkids, so doing some research on which dog breed lives the longest can help you choose a canine companion that will be part of your family for years to come. 

Research on how to convert dog years to human years has highlighted that size does matter when it comes to longevity, with the smallest dogs having almost double the expected lifespan of their biggest peers. 

Giant breeds, like the Great Dane, tend to age in fast motion and rarely exceed eight years, while many terrier breeds can live up to 20 years with the right care. We dug deep into doggy longevity to figure out which dog breed lives the longest, here are the 10 that came out on top...
