Osaka - A toy poodle from Japan has fans all over the world declaring that the round brown fluff ball is the cutest dog in the world.

Mohu is widely considered the "cutest dog in the world" – at least in the eyes of her adoring fans online, who celebrate her spherical, fluffy beauty.

Yet, her owner Nanae has said she is still looking for explanations for the enthusiasm that videos and pictures of Mohu garner.

"I don't know why she's so popular," she said, as per the New York Post.

And it's not just the attention she gets on her Instagram and TikTok accounts. Mohu is just as much of a conversation-starter in person.

"She always gets looked at on the street, and I get asked all the time what breed she is," Nanae said.

In a video that has racked up more than 4.5 million TikTok views, the four-legged friend does nothing in particular besides simply dance on her hind legs. Yet, fans have gone wild.

"It’s Mohu, the World’s Cutest Dog!" one fan wrote.

Most of Mohu's videos are set to amusing music that capture the pup's lighthearted antics.

But viewers seem to be especially captivated by the dog's extremely round body shape and excess fluff.

"I feel we need to alert all scientists, Mohu might be the roundest thing on Earth," one fan joked.
