A stone-cold wire fox took the top prize — but a platinum blond bombshell is the true breakout star of the 2019 Westminster Kennel Club Dog Show.

Winky the sassy bichon frise slayed the crowd Tuesday with her relaxed approach to the agility challenge. Now the internet is turning this four-legged beauty into a bona fide viral sensation.

While her fierce competitors raced through tunnels and over and around obstacles, Winky calmly walked the runway to the top of the A-frame — and struck a pose before sauntering back down.

And when working the doggie version of a catwalk, Winky stopped once again as if acknowledging the cheers of her newfound fans.

In the end, however, Winky’s losing time of 192 seconds included 92 “faults” and made her fashionably late.

Still, it’s worth noting that there were boos when esteemed judge Peter Green declared King, a 7-year-old wire fox terrier, America’s new top dog Tuesday night.

We’d like to think it’s because the audience was well aware of who America’s real top dog is.
