British scientists conducted an extensive study involving more than 500,000 dogs of various breeds to find out which breeds have the longest life expectancy. The results of this study may be useful for those looking for the perfect four-legged friend.

Small breeds with long muzzles, such as dachshunds and greyhounds, have been found to generally live longer than larger dogs with short muzzles, such as the English bulldog. Females have a slight advantage over males in terms of life expectancy; There is an average difference of six months for the same breed.

According to published Scientific Reports According to the findings, this study is the first to consider the impact of factors such as breed, size, mouth shape and gender on the lifespan of dogs. It showed that an average-sized male with a flat muzzle had almost three times the risk of a short life compared to a small, long-nosed female. Miniature Dachshunds and Italian Whippets are classified as “long-lived”.

These studies show that the average lifespan of dogs is 12.5 years. However, French Bulldogs generally only live about 9.8 years due to breathing problems caused by their characteristically short muzzles. In comparison, Lancashire Heelers can live up to 15.4 years due to their physical structure. Source
