Longest Living Dog Breeds: Ultimate Guide to the Longest Living Dogs

Posted: 11/01/2023 | BY: Content Writer | Categories: Dog

As a dog owner, you likely wish your dog could stay with you forever. There are few things more heartbreaking than losing a pet. If you’re considering bringing a new dog into your family, you may be curious which breeds tend to live the longest.

On average, dogs will live 8-15 years. Different dog breeds tend to mature and age at different rates based on a variety of factors, including genetics and size. Of course, the unexpected can always happen and a dog may have a shorter life than expected due to accident or illness.  At the same time, dogs can live even longer than the average estimate, although this is rare. The Guinness World Record holder for the oldest dog ever is Bluey, an Australian Cattle Dog who lived to be 29 years and 5 days old in 1939.

Which dog breeds have the shortest life span?

Giant dog breeds tend to have the shortest average life expectancy among dogs. For example, the French Mastiff has an average lifespan of 5-8 years, and Great Danes are expected to live 6-8 years.


Is it true that mixed-breed dogs live longer than purebred?

On average, yes. According to Fetch by WebMD, mixed-breed dogs average lifespan is about 14 years, and purebred dogs average about 10 years. (4)

The exact reason for this difference is hard to determine. Some believe that dogs bred under certain standards, as purebred dogs are, tend to pass various health problems down through genetics.


Why do small dogs live longer than large dogs?

Cornelia Kraus, an evolutionary biologist at the University of Gottingen in Germany, determined that large dogs seem to age at an accelerated pace as compared to small dogs. (2) This pace seems to promote the quick development of abnormal cells, which can advance cancer and other illnesses very quickly.


How can I prolong my dog’s life?

While genetics certainly play a large role in lifespan, maintaining a healthy lifestyle for your dog is essential to helping him live as long as possible.

Food habits are especially important, as dogs who are overweight tend to be much more at risk for health problems. Work closely with your vet to determine the best food for your dog and the right amount for a healthy weight.

Preventative care is essential as well. Health problems that are caught early are generally much more treatable than those that have been left without treatment for an extended period of time. Be sure to take your dog to the veterinarian at least once a year, more often if your vet suggests.

Some other important health factors that can prolong your dog’s life include:

  • Dental Health: Poor dental care can promote the growth of bacteria, which can enter your dog’s bloodstream. Establish and maintain a dental care routine for your dog.
  • Exercise: Promotes heart health and immunity.
  • Spaying/Neutering: This procedure can prevent several health conditions and can add 1-3 years to a dog’s life.
