If there's one breed of dog that continues to divide opinion, it's the pug. You either love them, or you hate them. Some people find them utterly adorable, while others are put off by their eyes and constant wheezing.

If you want proof of this then take a gander at the following image, which shows just how strange an animal a pug is from an anatomical perspective. This week an MRI scan of a pug dog went viral on social media after many people were left disturbed by the dog's freaky appearance.

The image in question was first shared on Twitter by the actor, writer, and comedian Andy Richter, who uploaded a picture of the scan and captioned it: "My friend’s pug went to the vet."

His many followers were left alarmed and disgusted by the image, which currently boasts over 131,000 likes and almost 16,000 retweets.

Commenting on the image, and on the unusual anatomical properties of the breed in a recent interview, London-based vet Dr. Rory Cowlam told British newspaper The Independent that: "If you were to get a pug head cake and cut it to take a look down the middle, that is what you are looking at. This is a slice at the level of the eyes, looking head-on at the pug, just two or three inches further back."

He added: "We have, through human selection, bred them to look more like a human baby because we find that cute. But, unfortunately, that cute look is not very good for the animal."

And before you go thinking this is some sort of hoax, another Twitter user with the handle @Elwilson95 shared what she said was her cousin's pug's MRI scan, and it is equally as terrifying.

Emily wrote: "My cousins pug just had an MRI scan... I am howling [sic]".

Indeed, according to Pet MD, pugs are prone to a number of major health problems, such as Pug Dog Encephalitis (PDE) and canine hip dysplasia (CHD), as well as elongated palate, patellar luxation, stenotic nares, Legg-Perthes disease, entropion, keratoconjunctivitis sicca (KCS), hemivertebra, obesity, and skin infections. Nerve degeneration, demodicosis, and seizures.

And just in case you wanted to know what a human looked like in an MRI, well... it's not much better:

Looks like we're closer to pugs than we all thought...
