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.
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.
