If you’re looking to add a furry friend to your life and secretly hoping they’ll stick around long enough to attend your retirement party, you’re not alone. Choosing a dog breed known for longevity is a smart move—especially if you’re emotionally attached to the idea of a lifelong best friend (who isn’t?). While no dog lives forever (sadly), some breeds consistently beat the odds and stay by your side longer than others.
So, what dogs live the longest—and why? Let’s dig into the top long-lived breeds and what makes them the Methuselahs of the canine world. If you want more information on Methuselahs, read Genesis chapter 5 in the Bible. Wrap your brain around this one, he was the oldest living person recorded in scripture, yet he dies before his father.
Why Do Some Dogs Live Longer Than Others?
Before we name names, let’s look at the science (don’t worry—we’ll keep it light).
In general, smaller dog breeds live longer than larger ones. This is a bit counterintuitive, especially if you compare it to other species (elephants vs. mice), but in dogs, it holds true. Larger dogs age faster and tend to be more prone to health issues like joint problems, heart disease, and cancer.
Genetics, lifestyle, diet, exercise, and preventive veterinary care all factor into a dog’s lifespan. But some breeds seem to have hit the genetic jackpot. I once had a Labrador mutt that lived to 16 years of age. Her diet? It was mostly dry food, but in her later years, she would eat whatever she would forage from garbage cans. She once ate a half bucket of Kentucky Fried Chicken before I had a chance to stop her.
The Top Longest-Living Dog Breeds
Here are some of the canine champions of longevity—many living well into their teens and some even making it past 20!
-
Chihuahua
Average Lifespan: 14–17 years (and sometimes over 20!)
These pint-sized dynamos are one of the longest-living dog breeds. Fiercely loyal, brimming with personality, and small enough to fit in your tote bag, Chihuahuas may look delicate but are tough as nails. Their main health risks include dental issues and heart disease—but with proper care, they’re marathon companions.
-
Dachshund
Average Lifespan: 12–16 years
Dachshunds (a.k.a. “wiener dogs”) have a surprisingly long life for such a quirky body shape. While their long backs make them prone to spinal issues, especially if they jump too much, a healthy, well-managed Doxie can be with you for a decade and a half or more.
-
Toy Poodle
Average Lifespan: 14–18 years
Don’t let the fancy haircut fool you—Toy Poodles are brainy, active, and live impressively long lives. Their intelligence makes them easy to train (and hard to outsmart), and their hypoallergenic coat is a bonus for allergy sufferers.
-
Shih Tzu
Average Lifespan: 10–16 years
Bred as royal lapdogs in ancient China, Shih Tzus were basically born to be pampered. Their sturdy constitution and charming personality make them a great pick for long-term companionship, though they do need regular grooming to keep their coats healthy. And, their name is fun to say, especially when you cross a Shih Tzu with a Bulldog, you get bull…
-
Lhasa Apso
Average Lifespan: 12–15 years
Another regal pup, the Lhasa Apso was bred to guard Tibetan monasteries—so don’t be fooled by the cute looks. These dogs are independent, confident, and known to reach their mid-to-late teens with proper care.
-
Australian Cattle Dog
Average Lifespan: 12–16 years
An exception to the small dog rule, the Australian Cattle Dog (also known as the Blue Heeler) is a medium-sized breed that’s exceptionally hardy. One legendary Aussie Cattle Dog named Bluey holds the world record for longest canine lifespan at 29 years. That’s nearly three decades of tail wags! My Australian Shepherd didn’t live that long, but Duke sure loved to play fetch. He once grabbed a pile of leaves and set them at my feet, expecting me to somehow throw it for him. Another wonderful dog from my past.
-
Papillon
Average Lifespan: 13–17 years
Papillons (French for “butterfly,” a nod to their distinctive ears) are tiny, energetic, and surprisingly resilient. They thrive on activity and affection—and their long lifespan makes them a favorite among small dog enthusiasts.
-
Beagle
Average Lifespan: 12–15 years
Beagles are sniffing machines with big hearts and long lives. Their keen sense of smell and curious nature keep them active—and activity is great for longevity. Be warned: their noses might get them into trouble, especially near open snack bags. Who’s the most famous Beagle of all? Why Snoopy, of course. Snoopy has been around for over 50 years.
A Word on Mixed Breeds
Don’t discount the humble mutt! Mixed-breed dogs often benefit from what’s called “hybrid vigor,” meaning they may have fewer genetic disorders than purebreds. Many mixed breeds live just as long—or longer—than their purebred counterparts.
Shelters and rescue organizations are filled with long-living companions just waiting for a forever home. We found a Jack Russell mix breed in a dumpster that was thrown away shortly after birth. My wife and I nursed it back to health and our “Oreo” was the best dog we ever had and lived past 16 years. Unfortunately, he eventually died – on my birthday. Ugh.
Tips to Help Your Dog Live a Long, Healthy Life
Regardless of breed, your care plays a huge role in how long your dog lives. Here are some longevity boosters:
- Regular vet visits: Early detection is key to preventing and managing disease.
- A healthy diet: Skip the table scraps. Quality dog food goes a long way.
- Daily exercise: Mental and physical stimulation keeps them sharp and strong.
- Dental care: Don’t underestimate those tiny teeth—dental disease can shorten lifespan.
- Love and attention: Happy dogs tend to be healthier dogs. It’s science (and common sense).
Final Thoughts
If your goal is a dog who’ll stick with you through thick and thin (and probably several smartphones), these long-living breeds are a great place to start. Of course, every dog is different—just like people. Some may live longer than expected, while others face challenges earlier on. But if you choose a healthy breed and commit to lifelong care, you’ll be giving your dog—and yourself—the best shot at many joyful years together.
If you want a pet that will live longer, then consider a large parrot. They can live up to 100 years. The only problem is they poop at will and they don’t play fetch. So remember: dogs may not live forever, but the love they give lasts a lifetime.
