A poor pug was called the "cutest and most terrifying thing" after its MRI scan.
Comedian Andy Richter shared an image of his friend's dog during a scan - which caused "happy nightmares" for Twitter users with its bulging eyes.
He simply tweeted: "My friend's pug went to the vet."
And now a vet suggested the scan is "pretty odd-looking" and warned of the dangers of human breeding.
Dr. Rory Cowlam said: "Their faces have been shortened due to intensive breeding by humans, unfortunately.
"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."
Users didn't hold back with their comments, as one wrote: "That is simultaneously the cutest and most terrifying thing I have seen in my entire life. Thank you for the happy nightmares this image will bring me tonight."
Another added: "Amazing. Pugs may be the only creature to look exactly the same in X-Ray as in visible light."
