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.''
