Summary

Lewis County requires permanent microchip identification only for animals formally declared dangerous. Under Lewis County Code § 6.05.080(3), the owner has five business days after the designation, or after moving into the county with an already-designated animal, to get the microchip implanted, with the sheriff's office able to approve an alternate ID method on request.

These county ordinances apply to unincorporated areas of Lewis County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The owner or keeper of an animal which has been declared dangerous pursuant to this chapter or was declared dangerous in another jurisdiction with a substantially similar designation shall, within five business days of the designation in Lewis County or within five days of moving into Lewis County from another jurisdiction, cause the dangerous animal to be permanently identified by microchip. The sheriff or his or her designee may, but is not required to, provide for alternative methods of identification if appropriate and upon request of the owner or keeper.

Full Breakdown

This is not a general pet microchip mandate: Lewis County only requires it once an animal has been declared dangerous under LCC § 6.05.060 or carries a substantially similar dangerous-animal designation from another jurisdiction. § 6.05.080(3) then gives the owner or keeper five business days from the Lewis County designation, or five days from moving into the county with an already-designated animal, to have the animal 'permanently identified by microchip.' The sheriff or a designee may allow an alternative identification method instead, but only at the owner's request and only if the sheriff finds it appropriate; there is no automatic substitute.

Microchipping is one piece of a larger compliance package under § 6.05.080(2): the owner must also obtain a yearly certificate of compliance, arrange an inspectable proper enclosure, submit a sworn enclosure affidavit, post visible warning signage at every entrance and exit, provide current vaccination records (or a veterinarian's affidavit explaining why a vaccine is unavailable), and carry a bond or insurance policy of at least $500,000 covering injury or damage caused by the animal. All of it, including the microchip, must be in place within the same five-business-day window.

Violations & Fines

Missing the five-business-day microchip deadline is enforced as part of the broader § 6.05.080 compliance package: a violation found by a preponderance of the evidence draws the civil penalties in LCC § 1.20.040, and the owner cannot use the underlying dangerous-animal designation as a defense in that enforcement action, since § 6.05.080(4) limits the issue to whether this section was violated. The animal can also be impounded under an administrative warrant pending a § 6.05.105 impound hearing.

Frequently Asked Questions

Does every dog in Lewis County need a microchip?
No. Lewis County only requires microchipping under LCC § 6.05.080(3) for an animal that has been formally declared dangerous, either in Lewis County or in another jurisdiction with a similar designation; there is no general microchip mandate for ordinary pets in unincorporated Lewis County.
How soon must a dangerous dog be microchipped?
Within five business days of the dangerous-animal designation, or within five days of moving a previously designated dangerous animal into Lewis County, per LCC § 6.05.080(3); the sheriff's office may approve an alternative identification method instead, but only if the owner requests it.
What else must a dangerous dog's owner do besides microchip it?
LCC § 6.05.080(2) also requires a yearly certificate of compliance, a secure and inspectable enclosure, posted warning signs at all entrances, current vaccination records, and a bond or liability insurance policy of at least $500,000 covering injury or damage the animal causes.
