The 25 Dog Breeds With the Longest Life Spans

New Guineau Singing Dog

New Guinea Singing Dog, 18-20 years

While not the best breed for a house pet, the New Guinea Singing Dog sure does live a long time. They’re known for their signature howl and for being a rare breed native to the island of New Guinea.

Being that they’re still closely related to their pre-domestication ancestors, they aren’t great with children. Because they’ve had very little interbreeding, they still maintain a strong genetic line contributing to their long lives–18-20 years!
