Summary
Gilroy does not require microchips for every pet, but the City Code forces one on a dog after a second at-large nuisance finding, and again automatically once a dog is classified as a level 1, 2 or 3 dangerous dog, both within 20 days at the owner's expense.
§ 4.11. Public nuisances. ... (4) Cause or permit a dog or a wild or exotic animal to run or wander at large on any public property or privately owned or occupied premises without the consent of the owner or occupant. ... ... b. The owner/guardian or person with a right to control a dog that has been determined to be a nuisance a second time must have a microchip inserted into the dog by a licensed veterinarian within twenty (20) days of the designation as a nuisance the second time, for identification purposes. This requirement is at the owner’s expense. ... ... § 4.30. Regulation of dangerous dogs. ... (8) The owner/guardian or person with a right to control a dog that has been classified as a level 1, 2 or 3 dog consistent with sections 4.1 and 4.30 must have a microchip inserted into the dog by a licensed veterinarian, within twenty (20) days of the designation as a level 1, 2 or 3 dog, for identification purposes. This requirement is at the owner’s expense.
Full Breakdown
Gilroy's animal control ordinance, enforced by the animal control administrator under Chapter 4 of the City Code, ties microchipping to repeat problem behavior rather than to all dogs and cats citywide. Section 4.11 declares it a nuisance and unlawful for an owner to let a dog run at large; if an unsterilized dog is found to be a nuisance a second time, subsection (4)(a) requires the owner to have it sterilized, and subsection (4)(b) separately requires that 'the owner/guardian or person with a right to control a dog that has been determined to be a nuisance a second time must have a microchip inserted into the dog by a licensed veterinarian within twenty (20) days of the designation.' The owner must then supply the administrator with the microchip's identifying information for the city's licensing record.
Section 4.30 layers a second, independent microchip trigger onto the city's dangerous-dog program: once the administrator classifies a dog as a level 1, 2 or 3 dangerous dog under Sections 4.1 and 4.30, subsection (b)(8) requires the same 20-day, owner-funded microchipping and same duty to report the chip's information to the administrator for the licensing file. Both duties run alongside other consequences of these classifications, including mandatory sterilization of all level 1-3 dogs, enclosure and muzzling rules for level 2 dogs, and euthanasia for a level 3 determination once appeals are exhausted.
Violations & Fines
Failure to microchip within the 20-day window is enforced through the same infraction and misdemeanor penalty schedule in Section 4.9: a first violation of a chapter provision draws up to a $100 fine, escalating to $200 and then $500 for repeat violations within a year, with four or more violations of the same section becoming a misdemeanor punishable by permit revocation, a fine up to $1,000, and up to six months in jail.
