Just How Long Can You Expect Your Dog to Live? Look to Their Nose!
New study suggests that smaller dogs with longer noses live longer than their larger, flat-faced counterparts
Just how long can you expect your dog to live? Most dog people know that a Dachshund will usually outlive a Great Dane, but what’s at play? And how do other breeds fare? A new study of nearly 600,000 British dogs from more than 150 breeds determined to find out. The results were published in the journal Scientific Reports in February.

The researchers found that large breeds and breeds with flattened faces had shorter average life spans than smaller dogs and those with elongated noses. Female dogs also lived a little longer than males.
As a group, small breeds lived, on average, for 12.7 years versus 11.9 years for large breeds. This backs prior research on canines and other mammals, which has found that within a given species, smaller individuals generally outlive larger ones.
Of course, there are exceptions to these trends, and the researchers noted that the findings may not be applicable outside of Britain where breeding practices and gene pools may differ.
The study utilized a database of 584,734 British dogs gathered from breed registries, pet insurance companies, veterinary offices, and additional sources. Most of the dogs were purebred, representing one of 155 breeds. Crossbreeds were included too, with all mixes combined into a single category. Each breed was classified as small, medium, or large, and its head-shape characterized as flat-faced, medium, or long-faced.
Across all dogs, the median life span was 12.5 years, the researchers found, but average life span varied “quite spectacularly” among breeds, Dr. McMillan told the New York Times. At the top of the longevity list is the Lancashire Heeler, a small herding dog newly recognized by the AKC (see page 12), which averaged a remarkable 15.4 years. At the other end of the spectrum, the much larger Caucasian Shepherd Dog had an average life span of just 5.4 years.

Brachycephalic, or flat-faced breeds, lived for 11.2 years on average, while medium- and long-faced breeds had average life spans of 12.8 and 12.1 years.
More research is needed to determine what accounts for the differences in longevity. Some breeds are genetically predisposed to life-shortening health issues, but differences in lifestyle, environment, diet, behaviour, and more could play a role, the researchers noted.
The researchers also found that purebred dogs, grouped together, had average life spans of 12.7 years compared with 12.0 years for crossbred dogs. This finding contradicts some prior research which found mixed breeds to be healthier. The scientists noted that this could be due to the study combining all mixed-breed dogs—regardless of size or breed mix—into a single category.
“Now that we have identified these populations that are at risk of early death, we can start looking into why that is,” Kirsten McMillan, an author of the new study and the data manager at Dogs Trust, a dog welfare charity in Britain that led the research, told the New York Times. “This provides an opportunity for us to improve the lives of our dogs.”

The American Kennel Club currently recognizes 201 breeds. Of those, these 15 are the least common. We asked breed expert and AKC Executive Secretary Gina DiNardo to outline the unique qualities of these rare dogs.
