Yes! All dogs and cats in the City of Dallas must have a microchip, which serves as your one-time pet registration (Sec. 7-4.2.). A microchip is a permanent form of identification injected just below their skin. A microchip scanner can pick up the chip's unique ID code to identify the pet and your contact information if your pet is lost. Make an appointment with Dallas Animal Services to get your pet microchipped for $10.
