Beagle, 12-15 years
The Beagle, with its stereotypical “puppy dog eyes” ain’t nothing but a hound dog—a fact you’ll recognize immediately upon hearing that signature howl. Beagles were bred as pack hunters so they’re more than happy for your (or anyone else’s) company.
They are curious and clever, can sniff out anything, anywhere, and are the most popular hound breed among American dog owners. And living to 12-15 years that popularity is going to last a long time.
