Siba is the fifth poodle to scoop the prize, although the breed's last victory came way back in 1991.
Siba is named top dog
The stylish pooch wowed judges and audience members with her elegant and very distinct appearance!
Now that's what we call a look! I Did groomer get a prize too?
Siba fended off challenges from a host of other adorable pooches on her way to the top. They included fan favourite Daniel, a lovable looking Golden Retriever, a Havanese named Bono, and Wilma the Boxer who entertained the crowd with her goofy antics.
Despite the high-calibre competition, Siba's handler believes her dog was a worthy winner.
Talking to The Guardian, Chrystal Murray said.
"She's beautiful and has that something. She had something extra at a young age."
Siba saw off thousands of other pooches
The Westminster Dog Show is one of the biggest and most prestigious events on the canine calendar. This year saw 2,600 entries in 204 breeds and varieties from 19 countries.
That makes Siba's victory sound even more impressive. Will she return next year to defend the crown?
We think so. But with a haircut like that, she should start getting ready for it now!
