It’s no secret that we all want our canine companions to live as long as possible. However, recent research has revealed some surprising factors that may help us understand which dogs live longer. The breed’s size, face shape, and sex have all been linked to its longevity. Here is what the new study found.
New study suggests which dogs live longer
Small, long-nosed dogs tend to outlive their counterparts, new research shows.
Researchers controlled for size, facial structure, and sex, ultimately discovering that small, long-snouted female dogs tend to clock the longest lifespans among pure breeds, living a median of 13.3 years.
Dr. Kirsten McMillan from Dogs Trust led this enlightening study. While previous studies recognized that sex, face shape, and size contribute to canine lifespan, Dr. McMillan’s study was the first to examine their interactions and potential evolutionary connection (via The Guardian).
Using data from a sample size of over half a million dogs — both purebred and crossbred — researchers established the median canine lifespan to be 12.5 years, with females living slightly longer than males. Furthermore, an in-depth analysis of 155 pure breeds revealed size and snout length also affected longevity.
Which dog breeds are at risk of early deaths?
Flat-faced breeds have shorter median lifespans of 11.2 years. Their risk of a shorter life is 40% greater than those with medium-length snouts, such as Spaniels. Moreover, although trendy in recent years, brachycephalic breeds are susceptible to several health issues including breathing and skin problems.
Particularly at risk are the large, fur-covered Caucasian Shepherds with a median lifespan of just 5.4 years. On a more positive note, pure breeds had slightly longer median lifespans than crossbreeds at 12.7 years and 12 years, respectively.
In light of this study, Dr. McMillan emphasized its importance in aiding potential dog owners and breeders to make more informed decisions, aiming to enhance the well-being of our furry friends. “But more specifically, I think this provides an opportunity for us to improve the lives of our canine companions,” she said. “We are identifying groups that desperately need attention, so we can zone in on these populations and work out what the problem is.”
