With distinctively wrinkly faces, short muzzles and curled tails, the pug's popularity has seen them become a common feature in dog parks and Instagram feeds.
But one pug with features that are a little different has captured attention online. Nola, who is almost a year old, lives in the Netherlands with owners Gerjanne and Elieke Bijker. She is a "retro pug."
With a longer muzzle, large floppy ears and a full curly tail, it's clear that Nola isn't like the pugs we're used to seeing today.
"Her mom is fully pug and her dad is half pug and half beagle. Which makes her 75 percent pug and 25 percent beagle," Nola's owner Bijker told Newsweek. "Because the modern pugs are so overbred, they now cross pugs with other dog breeds. This way pugs can go back to their original and healthy state."
