A recently conducted extensive study has uncovered fresh information on which types of dogs typically have longer lifespans compared to others. The examination, which examined almost 600,000 domesticated animals throughout the United Kingdom, discovered that the length of life varies greatly based on breed, body size, and facial structure.
The average lifespan for dogs in the UK is approximately 12.5 years, with a range of 5.4 to 15.4 years across all breeds that were researched.
Although they are considered a “vulnerable native breed” by the Kennel Club, Lancashire heelers, which are believed to be a mix of Welsh corgis and Manchester terriers, were discovered to have the highest average lifespan.
In contrast, Caucasian shepherds have the shortest expected lifespan at 5.4 years, with Presa Canario at 7.7 years and Cane Corso mastiffs at 8.1 years following closely behind.
Pugs and other brachycephalic breeds have a higher likelihood of having a shorter lifespan.
According to a study by the Dogs Trust, which was published in Scientific Reports, flat-faced breeds like pugs and French bulldogs have a 40% higher chance of having a shorter lifespan compared to other breeds.
Medium-sized brachycephalic (flat-faced) dogs were found to have the lowest average life expectancies of 9.1 years for males and 9.6 years for females.
Although they face many health obstacles such as respiratory, gastrointestinal, and ocular conditions, researchers have noted an increase in the popularity of flat-faced dog breeds like pugs (with an average lifespan of 11.6 years) and French bulldogs (with an average lifespan of 9.8 years).
According to Dr. Dan O’Neill, the chair of the Brachycephalic Working Group, a combination of factors has caused a severe health and welfare crisis for dogs with flat faces. The group consists of members from the veterinary, breeding, and welfare communities.
He stated that this recent study highlights significant health concerns, as it shows that flat-faced dogs have a lifespan 1.5 years shorter than that of regular dogs.
“It is essential for the public to prioritize their health over the perceived cuteness of flat-faced breeds. We strongly urge anyone considering getting one of these breeds to pause and carefully consider their decision, ensuring they choose a dog with the best chance for a long and happy life.”
Mixed breed dogs typically have shorter lifespans compared to purebred dogs.
Dr. Kirsten McMillan from the Dogs Trust conducted a study that collected information from 150 breeds and mixed breeds from 18 sources in the UK. These sources included breed registries, veterinarians, pet insurance companies, animal welfare organizations, and academic institutions.
The Lancashire heeler, Tibetan spaniel, and miniature dachshund were among the breeds that had the longest lifespan, with an average of 15.2, 15.2, and 14.0 years respectively. Labradors and cocker spaniels also had longer lifespans than the average, at 13.1 and 13.3 years.
The researchers also discovered that larger dog breeds have a 20% higher chance of having a shorter lifespan compared to smaller dog breeds.
It was discovered that female dogs have a longer lifespan compared to male dogs.
According to the findings, female dogs (12.7 years) tend to have a longer lifespan compared to male dogs (12.4 years). Additionally, purebred dogs (12.7 years) were found to have a longer life expectancy than crossbreeds (12 years). This suggests that dog owners who choose crossbreeds in hopes of benefiting from their genetic diversity may not be making the best decision.
On the other hand, smaller breeds of dogs with elongated noses, like whippets, had the longest average lifespans of 13.3 years.
According to Dr. McMillan, our research has revealed that life expectancy differs depending on breed, body size, face shape, and sex. This is the first study to analyze and compare all of these factors in conjunction with evolutionary history.

The combination of various factors exacerbates the problem, such as the increased risk of shorter lifespan for medium-sized, flat-faced male dogs compared to small-sized, long-faced females.
This research has significant ramifications for the discussion on canine genetics and health. While it does not identify specific factors for early mortality, it does draw attention to certain groups that warrant further examination.
This research aims to assist breeders, policymakers, funding organizations, and animal welfare groups in making informed choices to enhance the well-being of companion dogs. It also seeks to educate owners on the various factors that impact the health and lifespan of their dogs, particularly when selecting a new pet.
