St Bernard Lifespan: How Long Do These Gentle Giants Live?

St Bernards are beloved gentle giants known for their friendly personalities, loyalty, and yes – their massive size. Originally bred as mountain rescue dogs in the Swiss Alps, today‘s St Bernards excel as devoted family companions. If you‘re considering adding one of these majestic dogs to your home, one key question is: how long do St Bernards live?

As a veterinarian, I‘m here to give you the facts on the St Bernard lifespan, factors that impact their longevity, and tips to help your gentle giant live the longest, healthiest life possible. Let‘s dive in!

What is the Average St Bernard Lifespan?

St Bernards have a relatively short lifespan compared to smaller dog breeds. On average, St Bernards live between 8 to 10 years. However, some may live only 5 to 6 years, while others can reach 12 years or more.

This lifespan range is typical for giant dog breeds. In general, the giant breeds like St Bernards, Great Danes, and Mastiffs have the shortest lifespans, with a median of 8 to 10 years. Large breeds like Retrievers and German Shepherds average 10 to 12 years, while small breeds often live 12 to 16 years or more.

So why the shorter lifespan for our extra-large canine friends? It mostly comes down to genetics and faster aging. Giant breed dogs age more quickly and are considered "senior" around 5 to 6 years old, while small breeds aren‘t seniors until 10 to 12 years. Big dogs also have higher incidences of certain health issues that can limit their lifespan.

The good news is, there are steps you can take to help your St Bernard achieve their maximum lifespan potential. Keep reading to find out how!

Factors That Impact a St Bernard‘s Lifespan

While genetics play a big role in how long a St Bernard will live, there are many other factors that can impact their lifespan for better or worse:

Diet & Weight

Proper nutrition is essential for St Bernards, especially during puppyhood when they have a lot of growing to do. Feed a high-quality, veterinarian-recommended dog food formulated for giant breeds. Avoid overfeeding, as obesity is a major health risk. St Bernards should have defined waists and be able to feel their ribs.

Exercise

St Bernards need daily walks and play sessions to stay mobile and prevent obesity. However, go easy on puppies and don‘t let them overdo it, as too much exercise can damage their developing joints. Avoid stairs until they are full grown.

Preventive Care

Regular vet check-ups, vaccinations, parasite prevention, and dental care help St Bernards avoid preventable diseases. Early detection of any health issues is key.

Breeding

Responsible breeders perform health testing on their St Bernards to screen for genetic disorders before breeding. This helps produce healthier puppies with potentially longer lifespans. Always choose a puppy from health-tested parents.

Spay/Neuter

Spaying female St Bernards before their first heat cycle nearly eliminates the risk of mammary cancer and prevents pyometra. Neutering males reduces their risk of testicular cancer and some prostate issues. However, talk to your vet about the best timing for giant breeds.

Health Problems That Impact St Bernard Lifespan

St Bernards are prone to several health issues that can affect their lifespan:

• Hip and elbow dysplasia
• Cruciate ligament tears
• Osteosarcoma (bone cancer)
• Dilated cardiomyopathy (heart disease)
• Gastric dilatation volvulus (bloat)
• Epilepsy
• Eye problems like entropion, ectropion and cherry eye

Keeping your St Bernard at a healthy weight, providing age-appropriate exercise, feeding a joint supplement, and knowing the signs to watch for can help reduce the risks of some of these issues. Partner with your veterinarian for personalized preventive care.

St Bernard Life Stages & Aging

Puppy (Birth to 18 months)

St Bernard puppies are irresistibly cute, but with their rapid growth rate, they have high nutritional needs and mustn‘t over-exercise. Feed a puppy food for giant breeds, avoid stairs, and start training and socialization early. Puppies need a series of vaccinations and deworming.

Adult (18 months to 5 years)

Your St Bernard may not reach their full adult size until 3 years old. Feed an adult dog food for giant breeds to maintain lean body condition. Brush and bathe them regularly, and keep up with preventive care. This is a great time to enjoy activities with your energetic gentle giant.

Senior (5 to 8 years and older)

St Bernards are considered senior around 5 to 6 years old. Signs of aging can include gray fur, cloudy eyes, stiffness, and lower energy. Schedule twice-yearly vet visits, consider a senior diet and supplements, and keep them mobile with low-impact exercise. Weight management is essential. Make any necessary accommodations like orthopedic beds or ramps.

How to Tell Your St Bernard‘s Age

If you adopted your St Bernard as an adult, you may wonder how old they are. Here are some general guidelines:

• Puppies have sharp, temporary teeth that fall out around 4 months. Adult dogs have a full set of 42 permanent white teeth.

• As dogs age, their teeth show more tartar buildup and wear. Yellowing or some missing teeth indicate a senior dog.

• Cloudy eyes or "lenticular sclerosis" often develops in seniors.

• Older dogs may have graying fur, especially around the face and muzzle. Their coats may thin.

• Seniors often develop stiffness, arthritis and lower energy levels compared to adults.

Your veterinarian can help determine your rescue St Bernard‘s approximate age. Ultimately, biological age, which considers genetics, nutrition, and health status, is most important.

Closing Thoughts

While St Bernards may not have the longest lifespans, the years they spend with us are full of devotion, joy, and slobbery kisses. By understanding the factors that influence their lifespan and taking proactive steps to support their health, you can help your gentle giant live their best life every day they spend by your side.

Remember, every St Bernard is an individual. With a combination of great genes, excellent care, and a dash of luck, who knows – your Saint could be setting records as the longest-lived St Bernard around! One thing I know for sure: the impact they make on our hearts is immeasurable, no matter how long we are blessed to call them our own.
