The host, who comes from a family of professional dog breeders, knows mostly of what she speaks.

Gabriel and Monse are going with triangles on their dog. “I want to pay homage to my home country and represent the Brazilian flag and Brazilian colors,” Gabriel explains.

Watch the clip above to see Wilson’s moves, some of the other shapes, plus what judge Lisa Vanderpump has to say about her dog and this challenge.

After this challenge comes the Ultimutt Challenge. For that one in this week’s episode, “Feliz Navidog,” the nine grooming duos still in the running groom their dogs “into various holidays.” Those are the looks they’ll show off on the dogwalk for the judges — Vanderpump, Jorge Bendersky, and Dr. Callie Harris — who will vote to name one Best in Show of the week and send another team home to the doghouse.
