First, second and third places were won by dogs dressed up as a nurse, the animatronic doll from Netflix's Squid Game and Wonder Woman respectively.
The event was organized by Lima's Park Service to provide safe recreation in open spaces during the COVID-19 pandemic.
Judges took into consideration creativity, originality and the participant's performance during the runway. Dogs whose humans were also dressed up got extra points.
"This costume is a tribute to all the nurses who have been doing an honorable labor," said Maria Pilar Lucas, owner of the first place winner.
During the event, dogs could also get free deworming and veterinarian consultations.
