The secret is in your nose. Scientists name dog breeds that live significantly longer than others

Researchers have discovered an interesting connection between animal noses and lifespan.

Humans and dogs have lived side by side for nearly 10,000 years, and now researchers believe they have discovered dog breeds that live much longer than others. Interestingly, researchers also found a link between longevity and noses, Science Alert writes.

In the new study, scientists used data from more than half a million dogs in the UK. The team notes that their study was initially aimed at helping people choose the healthiest, longest-lived dog breed possible.

According to the study’s lead author, Kirsten McMillan, this is the first study to examine how a dog’s lifespan varies depending on a wide range of factors, including:

  • races;
  • dimension;
  • face shapes;
  • ground.

The results of the study show that a medium-sized male with a flat face, such as an English bulldog, is almost three times more likely to live a short life than a small-sized female with a long muzzle, such as a miniature dachshund. or Italian greyhound.

Scientists examined nearly 150 breeds and crossbreeds and found that the average life expectancy of dogs in the UK was 12.5 years. At the same time, the average lifespan of French bulldogs is only 9.8 years.

Previous research has already shown that the short noses of flat-faced dogs allow them to look more like human babies, making them particularly cute in the eyes of humans. However, brachycephalic dogs are also susceptible to incredible respiratory problems that significantly impact their lifespan.

The scientists also found that the dogs with the longest life expectancy were Lancashire Heelers at 15.4 years, Tibetan Spaniels at 15.2 years, and Miniature Dachshunds at 14 years. Labradors follow them with 13.1 years. Scientists also found that women generally live slightly longer than men, with life expectancy averaging 12.7 years compared to 12.4 years for men. Scientists also discovered that pure breeds actually live slightly longer than hybrids.
