Summary

Unincorporated Harris County requires a microchip ID number before HCPH Veterinary Public Health will license any dog or cat over three months old. Dangerous dogs face a separate, stricter microchip-implant mandate tied to registration.

City-specific rules exist: Houston, and Baytown have their own microchipping rules that differ from Harris County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

5.2 In order to be licensed by HCPH VPH, the custodian must provide the identification number of the dog or cat's implanted microchip, a physical description of the animal, and proof that the animal is currently vaccinated against rabies.

Full Breakdown

1, the custodian of every dog or cat over three months old (excluding animal shelters) must have the animal licensed by HCPH Veterinary Public Health (HCPH VPH). 2 sets the microchip requirement directly: to be licensed, the custodian must provide the identification number of the dog or cat's implanted microchip, a physical description of the animal, and proof of current rabies vaccination. 9. Failure to license a dog or cat that is required to be licensed is a Class C misdemeanor under Sec 7. 1 requires that within 30 days of learning a dog is dangerous, the owner must register it with HCPH VPH, and registration is conditioned on the dog being 'implanted with an identifying computer microchip compatible with the scanning equipment utilized by HCPH VPH,' with that chip information reported to HCPH VPH, alongside a $50 annual fee, proof of spay/neuter, $100,000 in liability coverage, and a HCPH-approved secure enclosure. 14 and charge up to $5 for processing. 13).

Violations & Fines

Knowingly failing or refusing to license a dog or cat required to be licensed, which functionally requires the microchip number under Sec 5.2, is a Class C misdemeanor under Sec 7. For dangerous dogs, failing to meet the Sec 8.1 microchip-implant condition blocks registration entirely, and HCPH VPH enforces the secure-enclosure and registration package as a unit rather than accepting partial compliance.

Frequently Asked Questions

Do I need to microchip my dog to get a Harris County pet license?
Yes. Subchapter 5A, Sec 5.2 requires the custodian to provide the microchip identification number when applying for an HCPH VPH license, along with a physical description and proof of current rabies vaccination. There is no license path that skips the chip number.
Is the microchip rule different for dogs declared dangerous?
Yes. Sec 8.1 makes registration of a dangerous dog conditional on the dog being implanted with a microchip compatible with HCPH VPH's scanning equipment, on top of the county's standard licensing microchip requirement, plus a $50 annual fee, spay/neuter proof, and $100,000 in liability coverage.
What happens if I do not license my microchipped dog?
Knowingly failing or refusing to license a dog or cat required to be licensed is a Class C misdemeanor under Sec 7 of Subchapter 5A, enforced by HCPH VPH in the justice of the peace courts.
