They can make anyone an excellent companion. You can expect that adult males will stand at 27.5 in at the shoulder, but females come in a slightly smaller package.

Since they have a shorter lifespan than most breeds their owners tend to cherish every moment with them. 

St. Bernard Life Expectancy

On average St. Bernards usually live for approximately 8 to 10 years. This is a lifespan that is shorter than many other breeds out there.

Nonetheless, it is not uncommon for dogs who are of a larger size to have a shorter lifespan. Their huge size is responsible for their aging which is considerably faster than other dog breeds.

They also become more susceptible to life-threatening diseases like cancers.

Saint Bernard lifespan is shorter than the average lifespan of dogs which is usually around 10 to 13 years. Medium and small-sized breeds tend to live a bit more than this.

But with larger breeds, you can improve the quality of life and lengthen their time if certain measures are put in place.

Owners can prolong the lives of their St. Bernards if they institute proper nutrition and have set times for their dog and if they engage them in proper exercise.

Because St. Bernards have a shorter life span than many other breeds, you should pay close attention to his nutritional intake. You need to feed your St. Bernard food that is nutritionally dense because his life depends on it. 

The dog food that you feed him, should be of a high quality that is commercially manufactured or made at home. Large breed dogs tend to benefit from raw diets that are high in protein and low in fat.

This is because when large breed dogs are overweight they develop a host of diseases earlier in life.

 Commercially manufactured kibble can work as well, but they must be free of fillers and other ingredients that make them unhealthy.

They must also be high in protein and contain all the necessary nutrients that your St. Bernard needs. Whatever you decide, make sure that your veterinarian approves the diets just to make sure.

Visit The Vet Regularly

Breeding & Genetics

A proper diet, exercise, and trips to the vets can only get you so far. Part of prolonging your St. Bernards life span starts with genetics.

Knowing your dog’s family tree and genetic history can help you to prolong his life. Usually, if a dog’s parents can live a bit longer his offspring will follow suit.

Another thing that would be helpful is knowing the size of the parents. This is important because we know from research that animals of larger size tend to have a shorter life span.

So if you realize that your dog’s parents we’re slightly smaller than average this could mean that your dog may live a bit longer.

Another reason this is important is that many of the so-called purebred dogs are actually mixed. Research has also shown that mixed dogs have an edge when it comes to life span.

They tend to live a bit longer so if you find out that your St. Bernard is mixed with a breed of a smaller size then he may live longer.

Also, because dogs of a certain breed tend to suffer from specific illnesses butts by cross-breeding, this likelihood may be mitigated.

Overweight Saint Bernards Live Shorter Lives 

Research conducted by researchers at the University of Gottingen in Germany discovered that large breed dogs who gain excessive weight are more likely to have shorter life spans.

This is similar to human adults who are overweight. They are at greater risk for many lifestyle diseases, such as heart disease and diabetes.

A St. Bernards 8 – 10-year average can be improved by changing his lifestyle and just giving him the best food.

You should also consider the stage that your dog is currently at then you would need to feed a senior dog differently than you do your puppy.

Do Mixed St. Bernards Live Longer Than Purebred Ones? 

Mixed breeds have a slight advantage when it comes to the life span because they live a better longer than purebreds do. Numerous studies give credence to this claim.

We know that smaller breed dogs live the longest butts mixed breed dogs live longer than large breeds.

This is also true of St. Bernards but only in cases when they are mixed with smaller breeds.

If two large breed dogs were to ave have offspring, the lifespan will not be improved for that offspring in any way.

But if a large breed and a medium or small breed were to have offspring then the lifespan would be improved in that offspring because of the benefits of the longevity that the smaller breed brings.

The mix and lineage may also help to reduce the likelihood of some diseases faced by larger breeds here. The size of mixed breeds may also be different from that of purebred dogs, so this is a great way to tell.
