The 25 Dog Breeds With the Longest Life Spans

Jack Russell Terrier dog

Jack Russell Terrier, 20 years

Before they came to be fabulous house pets, Jack Russell Terriers spent centuries hunting foxes. It’s this innate characteristic that gives them almost ceaseless energy and drive. They’re independent, intelligent, and should really be owned by dog owners who know how to handle them. They have great overall health, an affectionate personality, and are great with families and strangers alike.

In addition to living to almost 20 years old, Jack Russell Terriers need constant stimulation so you better not have anything to do for the next couple of decades.
