St. Louis Animal Care and Control microchips dogs and cats at adoption and impound, and city ordinances under Title VI require updated owner contact information for licensed pets.
While St. Louis does not require microchipping for every privately owned pet, Title VI requires that every dog and cat impounded by Animal Care and Control be scanned for a chip and microchipped before release or adoption when not already implanted. Licensed dangerous dogs face stricter identification requirements that typically include both a chip and tattoo. Owners must keep registration data current with the chip provider so that Animal Care, SLMPD, and partner shelters can return lost pets quickly. The city participates in regional lost-and-found scanning networks.
Failure to update microchip records can delay return of lost pets and create owner-of-record disputes; impound and reclaim fees increase if a pet is unchipped; dangerous-dog declarations require maintained chip ID.
