Chicago FAQ
Is microchipping required for my pet?
Not for privately owned animals. Only CACC adopters and reclaimed-impound owners must accept a chip under MCC 7-12-310. Most vets recommend it because tags fall off and chips greatly improve return-to-owner rates.
How do I update chip registration?
Contact your chip manufacturer (HomeAgain, AKC Reunite, etc.) or use the AAHA Universal Lookup to find your registry. Update address and phone whenever you move; CACC matches numbers against current contact info.
Houston FAQ
Is microchipping required in Houston?
No general mandate exists, but every pet adopted from or reclaimed at BARC is chipped automatically. Most veterinary clinics implant chips during routine visits for under fifty dollars.
How do I update my pet's chip registration?
Locate your microchip number on adoption paperwork, then update your address and phone with the chip registry. AAHA's universal lookup tool finds the correct registry for any chip brand.
