Summary

In unincorporated Lewis County it is unlawful to let any animal, not just dogs, run at large on public property or trespass onto a neighbor's land without permission, under Lewis County Code § 6.05.030. A more serious version applies when a large or aggressive animal is loose and could cause substantial injury, which escalates the offense to a misdemeanor.

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.

"At large" means off the premises of the owner or keeper of the animal, and not under restraint by leash or chain or not otherwise controlled by a competent person. ... It shall be unlawful for the owner or keeper of any animal to negligently allow such animal to enter or trespass onto private property of another without the express permission of the owner or caretaker of said property; or to allow said animal to run at large onto any public property or the public right-of-way within Lewis County. ... Any owner or keeper who is found, by a preponderance of the evidence, to have violated any portion of this subsection (1) shall be subject to the civil penalties in LCC § 1.20.040. ... It shall be unlawful for the owner or keeper of an animal to knowingly allow that animal to be at large under subsection (1) of this section when that animal due to its size, habits, or natural propensities or instincts represents a potential threat of substantial bodily injury to people or damage to property and is not under the physical restraint of a competent person; provided, however, this section shall not apply to police dogs as defined in RCW 4.24.410.

Full Breakdown

LCC § 6.05.030(1) makes it unlawful for an owner or keeper to negligently let an animal trespass onto someone else's private property without permission, or to run at large on public property or the public right-of-way anywhere in Lewis County. 'At large,' defined in § 6.05.010(8), means off the owner's premises and not under restraint by leash or chain or otherwise controlled by a competent person. A first-tier violation is civil: the animal control authority, a law enforcement officer, or the prosecuting attorney may cite the owner on probable cause, and a finding by a preponderance of the evidence brings the civil penalties in LCC § 1.20.040.

§ 6.05.030(2) raises the stakes when the loose animal, due to its size, habits, or natural instincts, represents a potential threat of substantial bodily injury to people or property and is not under a competent person's physical restraint; only a law enforcement officer or the prosecuting attorney, not the animal control authority, can act on this tier, and an officer may arrest on the spot if the violation occurs in their presence. Police dogs under RCW 4.24.410 are excluded from this heightened tier. A conviction under subsection (2) is a misdemeanor, and a conviction strips the owner's ownership interest, transferring the animal to Lewis County, which may humanely destroy it unless the owner is acquitted.

Violations & Fines

A basic at-large violation under § 6.05.030(1) is a civil infraction carrying the LCC § 1.20.040 penalty schedule ($125.00 first offense, $250.00 for a repeat within 12 months). Letting a dangerous-by-nature animal run loose under § 6.05.030(2) is a misdemeanor punishable by up to 90 days in the county jail, a fine of up to $1,000 plus statutory assessments, or both, and a conviction forfeits the owner's ownership of the animal to the county.

Frequently Asked Questions

Do I have to keep my dog on a leash in unincorporated Lewis County?
The code does not phrase it as a blanket leash rule, but LCC § 6.05.030(1) makes it unlawful to let any animal run at large on public property or the right-of-way, and § 6.05.010(8) defines 'at large' as off your property and not restrained by leash, chain, or a competent handler.
What happens if a dangerous dog gets loose?
LCC § 6.05.030(2) makes it a misdemeanor, not just a civil infraction, when an owner knowingly lets an animal that could cause substantial bodily injury run at large unrestrained; conviction can mean up to 90 days in jail, a $1,000 fine, and forfeiture of the animal to Lewis County.
Are police dogs exempt from the at-large rule?
Yes. LCC § 6.05.030(2) expressly exempts police dogs as defined in RCW 4.24.410 from the heightened at-large offense that applies to animals posing a substantial injury risk, though the basic civil at-large rule in subsection (1) still covers ordinary trespass and roaming.
