Jack Russell terriers live the longest dogs in the UKwhile french bulldogs have the shortest lifespans, according to a new study.

Researchers from the Royal Veterinary College have found that on average, the life expectancy of male dogs is four months shorter than that of females.

According to the study published in the Scientific reports newspaper, the overall average life expectancy for dogs is 11.2 years.

The analysis is based on a sample of 30,563 dogs who died between January 2016 and July 2020, from 18 different breeds and crosses.

He revealed that Jack Russell terriers have a life expectancy of 12.7 years. Next come border collies (12.1 years) and springer spaniels (11.92 years).

Four breeds of flat-faced dogs, also called brachycephalic, have the shortest life expectancies. American Bulldogs live an average of 7.8 years, Pugs 7.7 years, English Bulldogs 7.4 years and French Bulldogs only 4.5 years.

Research backs up experts’ warnings that people should think twice before buying a flat-faced dog.

The lower life expectancies of flat-faced breeds are strongly associated with animals suffering from a number of conditions, including respiratory problems and spinal diseases.

The researchers said the results, presented in the form of life tables – a tool that lists the remaining life expectancy and the probability of death in a range of age groups in a given population – will allow owners to estimate precisely how long their pet dog can live.

Dr Justine Shotton, President of the British Veterinary Association, said: “These life tables provide important insight into the life expectancies of popular dog breeds in the UK and will be a useful tool for vets and owners. of animals to assess the welfare of the dogs.

“A worrying finding is the lower life expectancy of flat-faced breeds.

“Although the study does not prove a direct link between these breeds’ potential welfare issues and a shorter lifespan, the results remind future dog owners to choose a breed based on their health and not of their appearance.”

In both male and female dogs, neutered dogs have a longer life expectancy than their unneutered counterparts.

The breeding of flat-faced dogs was banned in Norway earlier this year after an Oslo court ruled the practice cruel and leading to human-made health problems and in violation of Norwegian animal welfare law .

Explaining health issues when appearing on This morning at the time, veterinarian Dr Scott Miller used the example of the British bulldogwho has very narrow nostrils and “virtually no nose”.

This means that the structures of their nasal passages are returned and they have an elongated soft palate.

“Which means they have trouble breathing [and] they overheat and also because of their shape they struggle with arthritis and tend to be overweight because you can’t exercise them as much,” Miller said.
