On the first Saturday of every month, the Porto CROA opens its doors to the public for guided tours between 11:00 AM and 4:30 PM at Travessa Águas Férreas de Campanhã. This initiative offers the opportunity to tour the facilities, learn about the municipal team's work, and adopt a pet on the spot. Participation is free, but advance registration is mandatory (for the October 3, 2026 date) via email (adocaoanimal@cm-porto.pt) or phone (228 349 490).
