Pugs have high health risks and can no longer be considered a typical dog from a health perspective, a new study suggests.
Experts are advising people not to buy the dogs until there is an improvement in their health and their body shape shifts to being less extreme.
New research from the Royal Veterinary College (RVC) in London has revealed the health of pugs in the UK is now substantially different and largely worse than other dogs.
Pugs are almost twice as likely to experience one or more disorders annually compared with other dogs.
According to the experts, these findings suggest the pug can no longer be considered a typical dog from a health perspective.
The flat-faced nature and body shape of pugs — behind many of their health issues — has seen them increase in popularity in recent years.
But researchers argue the health of the dog should be prioritised over people’s desire to own one.
They say urgent action is required to reduce the high rate of health issues associated with the breed.
Dr Dan O’Neill, associate professor in companion animal epidemiology at the RVC and lead author of the paper, said: “Although hugely popular as pets, we now know that several severe health issues are linked to the extreme body shape of pugs that many humans find so cute.
“It is time now that we focus on the health of the dog rather than the whims of the owner when we are choosing what type of dog to own.”
From 2005 to 2017 there was a five five-fold increase in Kennel Club registrations of pugs.
However, there is growing concern over health issues of the dogs stemming from the breed’s flat face, bulging eyes, wrinkled skin and tendency towards obesity.
These are all characteristics which are often considered cute by the public, the researchers suggest.
Until now the full scale of the health crisis in pugs has not been fully understood.
The study, led by the RVC’s VetCompass programme, compared the health of random samples of 4,308 pugs and 21,835 non-pugs.
Overall, pugs were found to be around 1.9 times as likely to have one or more disorders recorded in a single year compared to non-pugs, indicating a poor overall health status in the breed.
Compiling a list of the 40 most common disorders across pug and non-pug groups of dogs, pugs had a higher risk of 23 out of the 40 (57.5%) disorders compared with a lower risk of only seven out of 40 (17.5%) disorders.
Brachycephalic obstructive airway syndrome (BOAS) was the disorder with the highest risk in pugs, with the breed almost 54 times more likely to have the condition.
This reflects the common respiratory difficulties experienced by flat-faced (brachycephalic) breeds due to the shape of their faces.
Pugs were also at higher risk of many other conditions compared to non-pugs, including narrowed nostrils, skinfold infections and obesity.
But they did have reduced risk of some conditions, including heart murmur, aggression and wounds.
The researchers suggest their findings indicate many pugs may suffer from seriously compromised health and welfare because of the extreme body shape that humans expects of the breed.
To correct this, their body shape must shift towards a more moderate, and less extreme, shape if health and welfare issues for pugs are to improve.
While waiting for these changes, the advice from experts to the public is to stop and think before buying a flat-faced dog.
