While dogs are cherished members of our families, it’s a sobering reality that not all breeds are with us for the same length of time. Some dog breeds, often due to genetic predispositions or size, unfortunately have shorter lifespans. This list explores seven dog breeds known for their relatively brief time by our side. Understanding these breeds’ lifespans can help potential owners prepare for the journey and make the most of their time together, ensuring a fulfilling life for these beloved pets despite their limited years. Discover which breeds, although short-lived, leave an indelible mark on our hearts.
Some dogs are built like tanks but, unfortunately, don’t have the mileage to match. While their love is boundless, their time with us is painfully short. Big love often comes in big packages, but sadly, that size can work against them.
Giant breeds, in particular, tend to have shorter lifespans due to rapid growth, heart conditions, and joint stress. They live fast, love hard, and leave a paw print that lasts forever. It’s a cruel trick of nature but one worth embracing.
Saying goodbye too soon is the price we pay for having them at all—but oh, what a privilege it is! These dogs may be short-lived, but they live well, squeezing a lifetime of loyalty into just a few years.
Here’s a fascinating fact: Large dogs age nearly ten times faster than small breeds, meaning a five-year-old giant is practically a senior citizen. Now, let’s meet the heart-stealers who make every moment count.
7 Very Short Lifespan Dog Breeds
1. Dogue de Bordeaux
First things first—this breed is a tank on four legs. With its wrinkled face and powerful build, it looks like it could take on the world. Unfortunately, when it comes to lifespan, the Dogue de Bordeaux is on the shortest life expectancy list, living just 5 to 8 years.
Genetics plays a cruel joke here. As one of the most popular large breeds, its massive size puts immense stress on the heart, making heart disease a leading cause of death. Add in a higher risk of bone cancer and canine hip dysplasia, and you’ve got a breed that faces significant health problems early in life.
A balanced diet rich in high-quality dog food can support its overall health, while regular veterinary checkups help catch issues before they escalate. This breed is prone to obesity, so portion control is essential—no sneaky table scraps!
Despite its size, the Dogue needs regular exercise to keep those muscles strong. But here’s the trick—low-impact workouts are best. Think leisurely walks, not long-distance running, to prevent joint problems.
AKC reports that grooming is refreshingly simple. A weekly brush and a wipe-down of those adorably excessive wrinkles (to prevent infections) will keep them looking sharp.
For prospective dog owners, know this: The Dogue de Bordeaux typically lives a short life, but it makes every second count. Devoted, affectionate, and protective, this breed is a wonderful companion that gives everything it has—just in a shorter timeframe.
2. Irish Wolfhound
Let’s be honest—this breed looks like it belongs in a medieval castle. Towering over smaller dogs, the Irish Wolfhound is a gentle giant with an average life expectancy of just 6 to 8 years. It’s a cruel twist of fate—smaller dog breeds tend to live longer, while these majestic creatures burn out too soon.
Why so short-lived? Bone cancer is a major culprit, and its massive size puts a strain on the heart. The breed is also prone to hip and elbow dysplasia, making mobility an issue as they age. Genetics and sheer size work against them.
But don’t lose hope—proper care can make a difference. A proper diet, including lean proteins and joint-supporting supplements, can help extend their overall longevity. And while they need regular exercise, high-impact activities should be limited to prevent joint problems.

Grooming? A bit more effort than some other dogs. Their wiry coat needs regular brushing to prevent mats, and those long legs tend to track in everything from mud to entire tree branches.
What makes this breed special is its heart—both literally and figuratively. They bond deeply with their humans and are known for their gentle, affectionate nature. If you can handle the heartbreak of a short life, you’ll be rewarded with the love of a lifetime.
3. Bernese Mountain Dog
Few dogs capture hearts quite like this fluffy, tricolor sweetheart. But, alas, this wonderful companion belongs to the shortest-living dog breeds, with an average lifespan of just 6 to 8 years.
Why so short? Blame genetics and cancer—nearly half of these dogs will face some form of bone cancer or other health conditions. They’re also prone to hip dysplasia, elbow dysplasia, and other common health concerns that affect large breeds.
A proper diet can support their overall health. Feeding them high-quality dog food rich in omega-3s may reduce inflammation and support joint problems. Regular veterinary checkups can catch health issues early, and exercise regularly helps maintain a healthy weight.
Britannica claims that these dogs typically live for adventure, so they need room to roam. Whether it’s hiking or romping in the snow, they thrive on activity. But be warned—overexertion can make joint problems worse.
Grooming is a must. Their thick double coat sheds like a snowstorm, especially during seasonal changes. Brush them several times a week to keep that fur under control.
Prospective dog owners know this: They might not live long, but they love hard. Every minute spent with a Bernese is a minute well spent.
4. Neapolitan Mastiff
Meet the living legend of large breeds—a droopy-faced, wrinkled warrior with a short life but an unforgettable presence. With an average life expectancy of 7 to 9 years, the Neapolitan Mastiff faces various health problems, especially heart disease and joint problems.
Their massive size is both a blessing and a curse. Hip and elbow dysplasia are almost guaranteed, and bloat (gastric torsion) is a major concern. They have a higher risk of bone cancer.
To help extend their overall longevity, focus on a proper diet. Smaller, frequent meals can prevent bloat, while a balanced diet with joint-supporting nutrients can aid overall health.
Exercise? Yes, but with caution. While they enjoy regular exercise, their joints can’t handle excessive strain. Short, controlled walks work best.
Grooming is surprisingly easy—despite their massive size, a weekly brush and wrinkle-cleaning routine will keep them fresh. But don’t skimp on ear cleaning—those floppy ears trap moisture.
For those considering this breed of dog, know that the Neapolitan Mastiff is not just a pet—it’s a presence. Their short lifespan is bittersweet, but their loyalty, protection, and devotion make every moment count.
5. Great Dane
Let’s cut to the chase—this breed is a small horse. Known for its massive size, the Great Dane is both a gentle giant and a short-lifespan heartbreaker, with an average life expectancy of just 7 to 10 years.
Why do they belong to the shortest-living dog breeds? Their hearts simply can’t keep up with their gigantic frames. Heart disease is a major concern, alongside bloat (gastric torsion), which can be fatal if not treated immediately. Bone cancer and hip dysplasia are also common health concerns.
PetMD mentions that a proper diet is non-negotiable. They need high-quality dog food, but portion control is key—feeding them smaller meals throughout the day helps prevent bloat. Supplements for joint health can support their overall longevity.
Despite their intimidating size, they typically live for affection and couch time. They need regular exercise, but nothing extreme—gentle walks and playtime work best to avoid stressing their joints and heart.
Grooming? Surprisingly easy. A weekly brush and the occasional bath will keep them looking regal. But those big floppy ears? Clean them often to prevent infections.
For prospective dog owners, know that time spent with a Great Dane is precious. They may have a short life, but they love in the biggest way possible.
6. Leonberger
With a mane that could make a lion jealous, the Leonberger is a majestic, fluffy big dog. But despite its strength, this large breed is another member of the short lifespan dog breeds, with an average life of 8 to 9 years.
The biggest enemy? Bone cancer, hip and elbow dysplasia, and heart conditions. They grow fast—too fast. This rapid development strains their bones, leading to joint problems and arthritis at a young age.
A balanced diet packed with nutrients for joint health can help. High-quality dog food and fish oil supplements can ease inflammation and support overall health. Regular veterinary checkups are a must to catch health issues early.
Exercise is a balancing act—too much can wear down their joints, but too little leads to weight gain. Gentle swimming is a great option since it’s easy on the joints.
Purina claims that grooming is where things get real. That luxurious double coat? It sheds constantly. Daily brushing is ideal, and during shedding season, prepare for fur-nados.
For prospective dog owners, the Leonberger’s short life comes with a big heart. They are wonderful companions, fiercely loyal, and make every day feel like a royal experience.
7. Bullmastiff
The Bullmastiff is equal parts brawn and lovebug, known for its protective nature and devoted heart. But as with many large breeds, its average life expectancy is short, typically 8 to 10 years.
What are their biggest health threats? Hip and elbow dysplasia, heart disease, and bloat. Their massive size plays against them, putting extra stress on their joints and organs.
A proper diet can help. They need high-protein dog food to maintain muscle mass and smaller, frequent meals to prevent bloat. Joint supplements are a smart addition to overall longevity.
While they’re known for being laid-back, don’t let that fool you—regular exercise is essential. Short, structured walks and light strength training (like uphill walks) keep them strong without overloading their joints.
Grooming is blissfully low-maintenance. Their short coat only needs a weekly brush, but watch for skin folds—they can trap moisture and cause infections.
Prospective dog owners know this: Bullmastiffs live to protect and love their humans. Their short life is full of loyalty, devotion, and the kind of unwavering companionship that makes every moment worth it.
Final Thought
Choosing a dog from the breeds with the shortest lifespans is a decision filled with love but also with heartache. Unlike smaller counterparts like Yorkshire Terriers or Toy Poodles, these large breeds give us everything they have in a short amount of time. But ask any owner, and they’ll tell you—it’s worth it.
While we can’t change genetics, we can improve a dog’s health with the right care. A proper diet, regular veterinary checkups, and tailored health care from an early age can make a big difference. Every individual dog has unique needs, and certain breeds, like the Bordeaux Mastiff (aka French Mastiff) or Scottish Deerhound, benefit from joint supplements and low-impact exercise.
Looking for longevity? While Saint Bernards, Greater Swiss Mountain Dogs, and Doberman Pinschers belong to the shortest life spans, some breeds, like Border Collies and German Shepherds, typically live longer thanks to their sturdy genetics and high activity levels.
Even mixed-breed dogs sometimes have a long lifespan, benefiting from genetic diversity. But no matter the breed, the real key to a dog’s well-being is love, companionship, and quality time. The more a dog enjoys life, the richer those years become.
So whether your furry friend is a long-lived Cavalier King Charles Spaniel or a fleeting but unforgettable Great Dane, make every moment count. Because no matter how long a dog lives, the love they give is infinite.
Loving a short-lifespan breed means cherishing every second. While these dogs may not live long, with proper care, a balanced diet, and regular veterinary checkups, they can live healthier, fuller lives. Time spent with them may be brief, but their love lasts forever.
In examining the seven dog breeds with the shortest lifespans, we uncover insights into the interplay between genetics, size, and health predispositions. Breeds such as Great Danes and Saint Bernards, renowned for their impressive stature, often experience shorter lives due to rapid growth and increased strain on their organs. Similarly, breeds like the English Bulldog face genetic health challenges from breeding practices. Understanding these lifespan limitations emphasizes the importance of mindful breeding, regular veterinary care, and tailored wellness practices to enhance the quality and longevity of life for these beloved companions, underscoring the need for responsible pet ownership.
