On a recent Sunday, a Buenos Aires plaza transformed into a makeshift wilderness for an unusual group of teenagers.
Sofía, wearing a lifelike beagle mask, ran across the grass on all fours. Nearby, 15-year-old Aguara leapt through the air, clearing an obstacle course while imitating the precise movements of a Belgian breed dog. Others dressed as cats and foxes perched in the branches of trees, keeping their distance from curious onlookers.
