How liability works in Washington

What the rule is, and what you must show.

What the victim must show
You were bitten while in a public place or lawfully on private property, including the owner’s. The statute applies "regardless of the former viciousness of such dog or the owner’s knowledge."

Note: Washington’s strict-liability statute is bite-only. A scratch, knock-down, or chase injury is not covered by strict liability and would fall back to ordinary negligence.

Landlords & defenses

Who else can be liable, and what defeats a claim.

Landlord liability
Generally no — RCW §16.08.040 targets "owners." A landlord is reached only through common-law negligence, and only where they knew the tenant’s dog was dangerous and kept control.
Main defenses
TrespassingProvocation (full defense, §16.08.060)Police dogs

Provocation is a complete defense under RCW 16.08.060, and police dogs performing their duties are excepted via RCW 4.24.410.

What Washington dog-bite victims get wrong

Washington’s dog-bite statute is short and strict: under RCW §16.08.040 an owner is liable for a bite "regardless of the former viciousness of such dog or the owner’s knowledge." There is no one-free-bite grace period. But the word that matters is "bite" — like California, Washington’s strict-liability statute is bite-only, so a knock-down or a scratch pushes you back into ordinary negligence. Two defenses stand out: provocation is a complete defense under RCW 16.08.060, and police dogs doing their job are carved out. Landlords sit outside the statute and can be reached only through common-law negligence when they actually knew a tenant’s dog was dangerous.

Common questions

Is Washington a strict-liability dog-bite state?

Yes. RCW §16.08.040 holds the owner liable for a bite regardless of the dog’s prior viciousness or the owner’s knowledge.

Does Washington’s dog-bite law cover injuries other than bites?

No. The statute is bite-only. A scratch, knock-down, or chase injury must be pursued under ordinary negligence instead.

Is provocation a defense to a dog bite in Washington?

Yes — provocation is a complete defense under RCW 16.08.060, and trespassing also defeats a claim.

Can I sue a landlord for a tenant’s dog bite in Washington?

Not under the statute, which targets owners. A landlord is liable only through common-law negligence with knowledge of the danger and retained control.
