There are some large breed dogs that live longer than others, but why? And what can you do to increase your dog’s lifespan? Today I am sharing the secrets to mastering canine longevity so you can claim many more healthy years with your canine companion.

Unfortunately, when it comes to large and giant breed dogs the consensus is that large dogs don’t live long compared to smaller breeds.  And while this is true generally, it certainly isn’t true for all large breed dogs and doesn’t have to be true for your dog. 

In this post, you will discover:

  • 30 large dog breeds with the longest lifespan, 
  • 13 large breed dogs with the shortest lifespan
  • The factors that contribute to a dog’s life expectancy
  • Why giant breed dogs in particular don’t live long, and
  • How YOU can help your big dog live longer 

What Impacts a Dog’s Lifespan

Before we dive into the individual breed longevity analysis, let’s briefly cover some of the primary factors that contribute to a dog’s lifespan.

These are in no particular order.


Genetics can play a significant role in a dog’s lifespan. I have numerous blog posts on on the topic of genetics, and feel strongly that this is one of the most important factors affecting a dog’s health, temperament, and longevity. 

There is no doubt that even with the best, most responsible preservation breeding practices, some breeds are genetically predisposed to certain health conditions that can impact their longevity.

There is almost no way around that, unfortunately. 

That said, responsible breeding practices aimed at reducing genetic health issues can contribute to a longer lifespan.

Size and Breed

As I stated above, the consensus is that larger dog breeds tend to have shorter lifespans compared to smaller breeds. While this is true generally, individual variations exist between breeds and within each breed.  

Healthcare and Veterinary Attention

Regular veterinary check-ups, vaccinations (when needed), preventive care, and prompt treatment of health issues can significantly impact a dog’s lifespan.

Because healthcare is one of the biggest expenses for large dogs, owners may attempt to minimize this cost by going to the veterinarian less frequently, opting out of preventive care services, and trying home remedies as a first line of treatment.  

Nutrition and Diet

Another topic that has been covered extensively on this blog is diet and nutrition for dogs

Providing a well-balanced diet that meets a dog’s nutritional requirements is essential for their overall health and longevity.

Proper nutrition, either through a whole raw diet or a high-quality commercial diet, can help prevent obesity and certain diet-related health conditions.

Exercise and Physical Activity

One of the most neglected factors that affect how long a dog will live is regular exercise and physical activity.

Sufficient exercise is crucial for maintaining a dog’s physical and mental well-being; it helps manage weight, promotes cardiovascular health, strengthens muscles, and contributes to a longer, healthier life.  

Living conditions and environment

You may not know it, but the quality of a dog’s living conditions and environment can affect their lifespan.

Dogs that are exposed to harmful substances, extreme temperatures, neglect, or abuse may experience adverse effects on their health and well-being. 

I have seen this firsthand. 

Dogs that live in a home where there is a lot of yelling or abuse can become scared, insecure, or reactive. 

Just like with humans, dogs who experience this type of trauma can lose many valuable years of their lives due to the daily stress they live with.

Spaying / Neutering

While spaying or neutering a dog can have health benefits and reduce the risk of certain reproductive-related health issues, doing so too early in life, especially in large and giant breed dogs can shorten their lifespan. 

Most preservation breeders do not recommend spaying or neutering before a dog is 18 months old if not later.  

Lifestyle and Care

A dog’s lifestyle and the care they receive from their owner or caregiver can greatly impact their overall well-being and lifespan.

Providing a loving, safe, and stimulating environment, socialization, mental enrichment, and proper grooming all contribute to a dog’s quality of life and potential lifespan.

30 Longest Living Large Dog Breeds

While large breed dogs tend to have shorter lifespans compared to smaller breeds, the following are some large breed dogs that are known for their longevity. 

Keep in mind these are average lifespans for each breed based on American Kennel Club (AKC) data.  Individual dogs may deviate from these averages through premature death or a longer life.

Why Don’t Giant Breed Dogs Live Long?

While not all giant breed dogs will experience these issues, owners of giant breeds need to be aware of potential health problems and take proactive measures to promote their dogs’ health. 

Here are some common health concerns for giant breed dogs… Unfortunately, I have had personal experience with the majority of these in my many decades as a big dog owner

Hip and Elbow Dysplasia

Hip and elbow dysplasia are orthopedic conditions caused by improper formation or malalignment of these joints can lead to pain, lameness, and mobility issues.

While hip dysplasia is a hereditary condition, factors such as excessive growth rate, types of exercise, improper weight, and unbalanced nutrition can magnify this genetic predisposition.

Osteochondrosis Dissecans (OCD)

Osteochondrosis is the abnormal growth of the cartilage on the end of a bone around the joint. Osteochondritis dissecans (OCD or OD) is an inflammatory condition, particularly in growing large breed puppies (6 to 9 months), that occurs when the diseased cartilage separates from the underlying bone.

It most commonly affects the shoulder joint but the elbow, hip, knee (stifle), or hock (tarsus) may also be affected.

While the cause of OCD is unknown, this disease is more common in dogs receiving too much energy, protein, and calcium in the diet. Other factors may also include genetics, rapid growth, trauma, lack of blood flow, and hormonal factors.(1) 

OCD should not be confused with Panosteitis, a condition caused by the too-rapid growth of long bones in large and giant breed puppies which causes pain and inflammation. 

Gastric Dilatation-Volvulus (GDV) or Bloat

GDV, also known as bloat, is a life-threatening condition that occurs when a dog’s stomach becomes distended and twists on itself.

It is more common in deep-chested breeds, including many giant breeds, and requires immediate veterinary attention.

For more information on bloat, its causes, and what you can do to prevent and treat it, read Bloat In Dogs: 7 Simple Steps That Can Save Your Dog [FAST!].

Wobbler Syndrome

Wobbler syndrome is a neurological disease in large and giant breed dogs affecting the cervical (neck) spinal cord and has been referred to by various names such as cervical stenotic myelopathy, caudal cervical spondylomyelopathy, and cervical malarticulation/malformation syndrome.

Symptoms of Wobblers include neck pain, scuffing nails, stumbling, incoordination (ataxia), difficulty rising, and difficulty walking. These symptoms can progress and worsen over time.

For much more information on Wobbler Syndrome, read Wobbler Syndrome – What Dog Owners Must Know About This Silent Killer.

I recorded my discussion with our neurologist when my Mastiff, Junior, was diagnosed. You can watch that short video here.

Dilated Cardiomyopathy (DCM)

Some large breed dogs, such as Doberman Pinschers and Great Danes, may be prone to certain cardiac conditions like dilated cardiomyopathy (DCM), a condition that affects the heart muscle’s ability to pump blood effectively. 

While some opinion-based journal articles in 2018 suggested a link between grain-free diets and the risk of DCM, to date there has been no conclusive evidence linking the two.  (2)


Osteosarcoma is an aggressive cancer that typically affects the leg bones of middle-aged to older large and giant breed dogs.

It has usually spread throughout the body at the time of diagnosis, so even with tumor removal and chemotherapy, the median survival time is only 8-11 months. 

I lost my first Mastiff, Maya, to osteosarcoma. We were given only 4 months from the date of her diagnosis until we said our heartwrenching goodbye.

I will be writing more on canine bone cancer this year as there is a great deal of research being done to find causes, markers, and preventions.  Stay tuned by signing up for my Big Dog Weekly newsletter,

Cruciate Ligament Injury

The cranial cruciate ligament (or CCL) is one of the most important stabilizers inside the knee (also called “stifle”) joint.  In humans, it is called the anterior cruciate ligament (ACL).  Rupture of the CCL is one of the most common reasons for hind limb lameness, pain, and subsequent arthritis.

Unlike in humans, a traumatic or sudden rupture can happen in dogs but is quite rare. More often it is caused by the aging of the ligament (degeneration), obesity, poor physical condition, conformation, and breed. In other words, the ligament injury is a result of subtle, slow degeneration that has been taking place over a few months, or even years, rather than the result of sudden trauma to an otherwise healthy ligament. (3)

Large breed dogs with a high incidence of CCLD are the Rottweiler, Newfoundland, Mastiff, Akita, Saint Bernard, Chesapeake Bay Retriever, and Labrador Retriever.


This condition is one of the most obvious, yet most commonly overlooked factors in a shortened life span.  Perhaps this is due to the indifference or denial we have about our weight, or perhaps we are too close to our dogs to see the truth. 

Whatever the reason, obesity in large and giant breed dogs can exacerbate joint issues and increase the risk of other health problems.

Maintaining a healthy weight, particularly as your puppy is growing, through proper diet and exercise is essential.  

How You Can Help Your Big Dog Live Longer [6 Tips]

Fortunately, your large dog is not doomed to live a life limited by disease and hardship. Many large dogs that live long lives do so well into their teens with relatively good health along the way.

I believe yours can, too!  

Here are 6 tips for how you can improve your big dog’s lifespan and quality of life. 

1. Find a Reputable Preservation Breeder

First and foremost, I encourage you to purchase your puppy or dog from a reputable preservation dog breeder.  

I get that your neighbor down the street has jumped on the doodle breeding bandwagon or that you feel an emotional pull toward the discount puppy in the pet store window, but rather than falling prey to the marketing ploy of backyard breeders, can I encourage you to take your time and do your due diligence before buying a puppy.  

Go to a local dog show and talk to people with the breed you are considering.  Use this guide to help you with what questions to ask dog breeders to weed out those that aren’t a good fit and find the puppy you are looking for.  

I also encourage you to connect with your breed’s national breed club.  You can find links to most large and giant breed dog clubs at the bottom of this page.  

2. More Exercise

As I just stated above, most dogs are not given enough exercise to keep them in optimal health, mentally and physically.

According to research done by the Dog Aging Project, physical activity was robustly associated with better cognitive outcomes in over 11,500 dogs studied. (9)

Large breed dogs should get at least 30 minutes to 2 hours of vigorous exercise per day.  If you have a working, herding, hound, or sporting breed you should aim for the upper amount of this range. 

Ideally, exercise should be made up of both structured activities like walks or jogs and unstructured ones like playing fetch, scent games, off-leash play, etc. 

Remember, physical exercise is good for you, too!  So get out there and work up a sweat!

3. Raw Diet

There is no denying that commercially produced dry kibble is a far cry from a dog’s ancestral diet.  

And, like humans, your dog’s diet forms the foundation of his/her health.  As they say, garbage in, garbage out.  You can’t expect your dog to exceed its life expectancy if you are filling them with the equivalent of garbage.

To provide the very best nutritional foundation for your dog’s health, immune system, and longevity, I highly encourage you to consider feeding a more natural, preferably raw, diet

4. Mental Stimulation

Imagine a life where the only decisions you had to make were deciding where to lay, who to sniff, and how much to bark at feeding time. 

Large Breed Dogs That Live Longer: Canine Longevity Secrets

Sadly, this is the boring, monotonous life most dogs lead.  

What most dog owners don’t realize is that mental health affects physical health in dogs, just like it does in humans. As a result, activating your dog’s mind prevents premature aging.

Dogs thrive on consistent mental stimulation. 

Consider playing brain games like hide and seek, purchasing brain-stimulating toys like those from Nina Ottosson, teaching new tricks, working on obedience training, starting a new activity like agility or nose work, etc.  

Think creatively and have fun with your dog!  

5. Socialization

Wolves in the wild are not solitary animals. They live in tightly connected packs, working together to hunt for food, raise the young, and care for one another.  

Domesticated dogs are no different.  They are relational creatures who need companionship just as much as we humans do.

Starting when a puppy is born, proper socialization is as important as a balanced diet.  Early exposures to the world around them ensure your puppy matures into a confident, bomb-proof dog.

Without this socialization, dogs can suffer from fear, reactivity, anxiety, and a myriad of health sequelae as a result.  

Scientists working with 25,000 dogs in the Dog Aging Project published interesting findings from their research in Evolution, Medicine & Public Health:  

“This does show that, even for our companion dogs, having those strong social connections and social companions is important. Overall, it’s good for your dog to have social support around, in the form of other people and other dogs. Dogs are social animals, just like us, so they benefit from being around others.”

brianah Mccoy, phd candidate, lead author

These findings illuminate behavioral and environmental modifiers that might promote healthy aging across species — for instance, social companionship is good and isolation is bad. (5)

Here’s the bottom line…

Force-free, fear-free socialization is key to your dog’s health, happiness, AND longevity (when done right).  

6. Lower Stress Environment

In humans, biological age increases with stress, but returns to baseline following recovery from stress based on research published in Cell Metabolism.(6)

Experts say exposure to stress can cause inflammation and damage to DNA in cells, which in turn can accelerate aging. 

Large Breed Dogs That Live Longer: Canine Longevity Secrets

Stress in dogs is no different.

When dogs are living in an environment where they cope with fear, anxiety, malnutrition (or over-feeding), isolation, abuse, etc., this stress causes premature aging. 

The most unexpected outcome of the Dog Aging Project had to do with kids: More time with children, it appears, is linked to poorer dog health.

Whether this is because owners are spending less time with their dogs as a result of having human children or because the environment in a home with children tends to be more loud and chaotic, researchers don’t know. 

No matter the reason, I would encourage you to consider the environment your dog is living in.  Pay attention to any calming signals or signs of stress he may be showing.  

If yelling or loud behavior is commonplace, consider teaching everyone how to use their indoor voice.  

If you are in a home where there is abuse of ANY kind, for your safety and the health and safety of your children and dogs, get out! 

Pay attention to your gut.  If you are stressed, your dog is, too!

Large Breed Dogs That Live Longer: Canine Longevity Secrets There are some large breed dogs that live longer than others, but why? And what can you do to increase your dog's lifespan? Today I am sharing the secrets to mastering canine longevity so you can claim many more healthy years with your canine companion.

FAQs About Dogs That Live Longer

There is no maximum lifespan for a dog, though the longest-living dog is reportedly a Rafeiro do Alentejo named Bobi, who lived to be 31 years old. The average lifespan for a dog of his breed is 10-14 years.  

Most small breed dogs live 10-15 years, medium-sized dogs 10-13 years, large breed dogs 10-12 years, and giant breed dogs 8-10 years on average.  

While there are no foods that are guaranteed to make your dog live longer, feeding a fresh, natural diet has, for me, been linked to better health outcomes overall for my dogs. 

Unfortunately, no conclusive studies are declaring the superiority of raw diets over commercial kibble, however, I did find this opinion article published in the Canadian Veterinary Journal with one veterinarian’s perspective. 

“Some of the best informed and conscientious clients are feeding their dogs and cats RMBDs. While raw pet foods are not suitable for most owners or all pets, some dogs and cats are healthier on these diets. Raw diets are effective in the management of some medical problems, especially gastrointestinal dysfunction. They can also resolve inappetence, obesity, and poor hair coat.” (10)

At the end of the day, it is up to you, the owner, to decide what diet is right for you and your dog.

Researchers in the UK found that among 30,563 dogs studied female dogs lived longer than male dogs, but not by much — the average life expectancy for female dogs was 11.41 years, while the average life expectancy for male dogs is 11.07 years. (7)

Noted in this study was the issue of neuter status – whether or not a dog was spayed or neutered – and how that affected their lifespan.  

“Neutering was associated with an elevated life expectancy at age 0 for both sexes compared to their entire counterparts, and this longevity advantage from neutering was higher in female dogs than in male dogs.”

But interestingly, while neutering did reduce or eliminate the risk of pyometra, a potentially life-threatening condition that occurs in 2% of entire female dogs under 10 years, it is linked to an increased risk of joint disorders and several types of tumors such as lymphoma and hemangiosarcoma, especially in females.

The Dog Aging Project (DAP) Health and Life Experience Survey of 27,541 companion dogs, identified the 10 most commonly reported medical conditions in each of the 25 most common dog breeds within the DAP cohort. 

Researchers compared the lifetime prevalence estimates of these medical conditions between mixed-breed and purebred populations and this is what they reported:

“Purebred dogs in the DAP did not show a higher lifetime prevalence of medical conditions compared to mixed-breed dogs, and a higher proportion of purebred dogs than mixed-breed dogs had no owner-reported medical conditions. Individual breeds may still show higher lifetime prevalence for specific conditions.” (8)

Compared to a dog that is overweight or obese, yes. A dog that is at its optimal weight for its body structure will suffer from fewer weight-related health conditions such as heart disease, diabetes, arthritis, and a compromised immune system.

However, when comparing different breeds to one another, for example, a Greyhound to a Labrador retriever, weight is less determinative of a dog’s life expectancy.  Greyhounds live on average 10-13 years while Labrador retrievers, a heavier-boned dog breed, live 11-13 years on average.
