10 dog breeds that live the longest

If you're someone who's already thinking about long-term commitment before picking a pup, good news: some dog breeds are naturally wired to live longer, healthier lives than others. And it’s not always the tiny purse dogs or the designer mixes that make the cut. In fact, some of the longest-living dog breeds are also the most active, loyal, and low-maintenance companions around.

This tiny breed may look delicate, but don’t be fooled. Chihuahuas are some of the toughest little canines on the planet. With an average lifespan of 14 to 17 years—and some even hitting 20—they’re the marathon runners of the dog world. What’s their secret? Low body fat, high metabolism, and minimal genetic issues compared to many bigger breeds. Plus, they’re not prone to joint problems as frequently as larger dogs.

Next on the list is the Toy Poodle. Don’t let the fancy haircuts fool you; this is one brainy, hardy little breed. Toy Poodles often live 14 to 18 years and have fewer health issues. They're also super responsive to training, which makes it easier to keep them mentally sharp and emotionally balanced as they age. One key to their long life? Consistent stimulation—these pups thrive when they’re challenged mentally, not just physically.

Speaking of smart dogs, you’ve got to love the Jack Russell Terrier. These little firecrackers live life in fast-forward—and they often do it for 16 years or more. Jack Russells are known for being energetic, fearless, and virtually tireless, which contributes to their long lifespans. They’re also less likely to suffer from the kind of degenerative diseases that plague large breeds. Keep them busy, keep them social, and they’ll stick around well into their senior dog years, still acting like they’re two years old.

The Dachshund might not seem like a longevity champ at first glance, especially with their stubby legs and long backs. But surprisingly, this breed often lives 12 to 16 years, with some reaching 17 or 18. Of course, their long spines make them prone to disc issues, so it's crucial to keep them at a healthy weight and avoid letting them jump on and off furniture. But with a balanced lifestyle, they can be your forever shadow for a very long time.

Another breed with good longevity is the Shih Tzu. Originally bred as royal lapdogs in China, Shih Tzus tend to live around 14 to 16 years, and they’re incredibly affectionate, gentle, and sturdy for their size. What makes them age well? They’re generally low-stress dogs. They don’t need tons of exercise, they adapt well to apartment life, and their compact build helps avoid major joint issues. Of course, those long coats need maintenance, but hey, a little grooming goes a long way if it means more years of companionship.

Then there’s the Miniature Schnauzer, a breed that’s more resilient than it looks. These wiry little dogs tend to live 13 to 15 years and are incredibly alert, intelligent, and adaptable. One of the reasons they live so long is because they’re prone to fewer congenital issues. However, they can develop diabetes and bladder stones, so regular vet checkups and a balanced diet are a must. Still, with that bushy beard and loyal personality, most owners are happy to do what it takes to keep them thriving for over a decade.

Don’t sleep on the Papillon, a small breed with butterfly-shaped ears and the heart of a lion. Despite looking like something out of a fairytale, Papillons are surprisingly tough and often live 14 to 17 years. They’re high-energy, easy to train, and less prone to the respiratory issues that plague other toy breeds. Their secret sauce for longevity? They age gracefully thanks to their alert temperament and agile, athletic build. Give them room to run, and you’ll have a happy Papillon bouncing around for years.

We can’t forget the Beagle—a medium-sized breed that regularly makes it to 15 or even 16 years. Known for their soulful eyes and strong sniffers, Beagles are built for stamina. They were bred for hunting, so their robust constitution makes them less prone to genetic disorders compared to some other medium dogs. But a word of caution: they love food. Like, really love food. Obesity is their kryptonite, so portion control and exercise are key if you want them to reach those golden senior years.

One breed that often flies under the radar when we talk about longevity is the Australian Cattle Dog, also known as the Blue Heeler. These working dogs are absolute tanks when it comes to health and energy. The oldest recorded dog in history was actually an Aussie Cattle Dog named Bluey, who lived to the ripe age of 29. Yup, 29. That’s not a typo. While most average out at 13 to 16 years, they can easily go beyond that with good care. Their secret? A life full of purpose, routine, and lots of physical activity.

Rounding out our list is the elegant and quirky Lhasa Apso. This Tibetan breed, originally bred as a monastery watchdog, isn’t just cute—they’re tough as nails. Lhasas often live between 15 and 20 years, making them one of the longest-living dog breeds ever. They’re alert, loyal, and slightly aloof, but their ability to adapt to new environments and bounce back from stress makes them ideal long-term companions. Just don’t expect them to perform tricks for strangers—they’ve got that ancient monk energy and aren’t here to entertain.

If you’re looking for a dog that will be around for long, your best bet is a small-to-medium breed with a solid health history, lots of mental stimulation, and an active lifestyle. And while genetics play a big role, you’ve also got a lot of power as a pet parent. Feed them real, nutritious food. Take them for regular vet visits. Brush their teeth. Walk them every day. And most importantly, show them love. A happy dog is almost always a healthier dog. Dogs teach us how to live better lives—present, playful, and full of heart. So if you’re blessed with one of these long-living breeds, count yourself lucky. Just be ready to share your bed, your snacks, and your soul for a very long, wonderful time.
