A recent study has brought to light interesting data on the longevity of companion dogs, with highlight for the breed Jack Russell Terrier, which proved to have the highest life expectancy among dogs domestic. According to research, these pets have an impressive average lifespan of 11.2 years.
The research went further and analyzed the differences between the sexes of the animals, revealing that male dogs tend to live slightly shorter, with an average of 11.1 years – about four months less than the average general.

Longest-lived dog breeds
The study in question was based on a random sample, including 30,563 dogs of 18 different breeds and crossbreeds. These dogs, all UK residents, passed away during the period 1 January 2016 to 31 July 2020.
The data collected indicated that Springer Spaniels (with a life expectancy of 11.92 years), Border Collies (12.1 years) and Jack Russell Terriers (12.7 years) lead in terms of longevity. However, breeds with flat muzzles, such as French Bulldogs (4.5 years old), Bulldogs English (7.4 years), Pugs (7.7 years) and American Bulldogs (7.8 years) exhibited the lowest expectations of life.

These results corroborate the concerns expressed by experts regarding short or flat muzzled breeds. The caveats are clear: prospective owners should carefully choose these breeds, as many of these dogs face respiratory problems and spinal disorders, factors directly linked to the reduction of their expectation of life.
Interestingly, the study also revealed that neutered dogs, regardless of gender, have a longer lifespan compared to non-neutered dogs. These findings reinforce the importance of paying attention to the health of dogs and the influence of castration on their longevity.
These results are valuable to future dog owners, aiding in making informed decisions when choosing a canine companion. It is worth noting, however, that a dog's life expectancy is not solely determined by breed. Factors such as proper veterinary care, a balanced diet, regular exercise and a safe and loving environment are also crucial.
Adopting a healthy lifestyle and meeting the specific needs of each breed can make a big difference, contributing to a longer and happier life for your pet.
