Which Dogs Live The Longest?

Our beloved dogs don’t live as long as we do unfortunately. It is reality and something that must be dealt with emotionally for all dog owners.

Whilst it may be tempting to find dogs with the longest life expectancy, it is actually quite difficult to put a finger on exactly what causes dogs to age and why some dogs live longer than others. Although they are of the same species, different breeds age at very different rates. Overall, the question of which dogs live the longest still eludes scientists and veterinarians alike.

In this post, we provide you with some useful information that will allow you to make the most informed choices when it comes to a dog with higher life expectancy. And with the help of Web MD, we will also provide the average life span of the most popular breeds of dogs.

Do you know the life expectancy of your dog? Find out now…

Bruce Fogle, DVM, in his book Caring for Your Dog: The Complete Canine Home Reference, says the median life expectancy of dogs is 12.8 years. But dog life expectancies vary widely by breed, ranging from breeds that can live 16 to 20 years (the rare Mexican breed, the Xoloitzcuintle, has a life span of 15-20 years; the Irish Wolfhound has an estimated 6- to 8-year life expectancy.

But there is one concrete piece of advice experts can give people looking for a dog breed with a long life span — think small.

Dog Life Span: Big vs. Small – Nearly 40% of small breed dogs live longer than 10 years, but only 13% of giant breed dogs live that long. The average 50-pound dog will live 10-12 years. But giant breeds such as great Danes or deerhounds are elderly at 6-8 years.

Kimberly Greer, PhD, an assistant professor at the School of Natural Sciences and Mathematics at Indiana University East, co-authored a study that showed that dogs weighing less than 30 pounds lived the longest. The study analyzed data from more than 700 dogs in 77 breeds. “It’s the weight, not the height, that matters,” Greer says. “Some dogs are short, like the English bulldog, but can still weigh 60 or 70 pounds. They wouldn’t be considered small breed dogs.”

Mark Stickney, DVM, director of General Surgery Services at Texas A&M University College of Veterinary Medicine and Biomedical Sciences, says although it’s not unusual to see a 17-year-old miniature poodle, a 12-year-old Labrador retriever is considered old, and any dog in the giant breeds — dogs weighing more than 100 pounds — is considered geriatric at 6-7 years.
“Generally speaking, the larger your dog is, the less time it will live,” Stickney says.

Dog Life Span: Male vs. Female – Steven N. Austad, PhD, a professor and researcher on aging at the department of cellular and structural biology at the University of Texas Health Science Center in San Antonio, says besides looking at small dogs, people looking for the longest-lived dogs also should look at mixed breed dogs and females.

“Female dogs tend to live a bit longer, although it’s not as pronounced as it is with humans,” Austad says.

Dog Life Span: Health Issues in Purebreds – Many purebred dogs come with a laundry list of health issues, which can cut into their life spans. Some are specific just to one breed, others can be a problem in many breeds. “Mutts haven’t gone through the inbreeding, so they should live longer, or at least be healthier than your purebred dogs,” Austad says.

Cancer is very common in dogs, and some breeds, such as boxers, golden retrievers, and Rottweilers, have unusually high rates of cancer. It’s been estimated that as many as a third of all Bernese mountain dogs die of cancer. Cancer is the most common cause of death in older dogs, and nearly 42% of dogs die of some form of cancer. When considering a purebred dog, experts say it’s a good idea to see what kinds of illnesses run in the breed. Many larger-breed dogs, such as Labrador retrievers, German shepherds, and Dobermans, can suffer from hip dysplasia, which can make a dog so lame it has to be put down.

Flat-faced dogs such as Pugs and Shih Tzus, known as brachycephalic dogs, are prone to breathing issues, which can cause overheating and even death. Cavalier King Charles Spaniels are prone to a heart condition called mitral valve disease, and cocker spaniels are susceptible to recurrent ear and eye infections.

Stickney said other common medical problems that crop up as dogs age include kidney and heart disease, as well as various structural issues, including bone and muscle ailments. Stickney advises pet owners looking for dog breeds with long life spans to find a small breed dog they like, research the breed’s health issues, and then find a good breeder who doesn’t have those problems in their bloodline. But getting good stock is only part of the battle, Stickney said. “Owners can play a big part in increasing their pet’s life span,” Stickney said. “Good nutrition, proper exercise, not letting our pets become obese; and good care, including regular veterinary care, will help our pets live healthier, longer lives.”
