Dog Bite Laws in Washington
Whether Washington holds a dog owner automatically liable, follows the one-bite rule, or takes a mixed approach — plus landlord liability and the main defenses.
How liability works in Washington
What the rule is, and what you must show.
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.
Provocation is a complete defense under RCW 16.08.060, and police dogs performing their duties are excepted via RCW 4.24.410.

| Basis | Statute — Statute — RCW §16.08.040 (+ §16.08.060 provocation) |
| What it covers | 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." |
| Landlord | 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. |

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.
