Is Washington a strict liability state for dog bites?

By Michael Shemtoub, trial attorney, Beverly Law. Updated November 2026.

What strict liability covers in Washington

RCW 16.08.040 makes the owner of any dog that bites a person liable for the damages the bitten person suffers. It applies regardless of the dog’s former viciousness or the owner’s knowledge of it, so for bites Washington has no one-bite rule.

Three facts must line up: the defendant owns the dog, the dog bit the injured person, and the person was in a public place or lawfully on private property, including the owner’s own.

Where the statute stops

• Lawful presence on private property. The owner’s consent, given in words or implied by the circumstances, makes a visitor’s presence lawful. The law will not assume that consent when the property is fenced or reasonably posted (RCW 16.08.050). In Sligar v. Odell (2010), a neighbor fell against a chain link fence and the dog behind it bit her finger through it. She was not lawfully on the fenced property, so the statute did not apply.
• Who counts as the owner. The statute names only the owner, but the word is read in light of the facts. In Beeler v. Hickman (1988), a couple who had lived with, cared for and had exclusive possession of a dog for three years denied owning it. The court held a jury could find them owners anyway.
• Bites only. The statute speaks of a dog that bites and a person bitten. Other injuries need a different legal theory, covered in the next section.

Knock-downs and other injuries without a bite

A dog that jumps on someone or knocks a jogger down can cause serious injuries without biting. Those claims rely on Washington common law.

In Johnston v. Ohls (1969), a dog ran into the street and collided with a motorbike, injuring the rider and his young daughter. No bite was involved. The Washington Supreme Court applied the common-law rule: when the owner knows or should know the dog has dangerous propensities, any injury the dog causes makes the owner prima facie liable without proof of negligence.

Without that knowledge, the claim is negligence. In Arnold v. Laird (1980), the court explained that negligence can be shown when an animal is not kept under the control a reasonable person would use, in circumstances where someone could foreseeably be hurt, and the injury follows. How much control is needed depends on the whole situation, including the animal’s past behavior. The Beeler court noted that these common-law rules also reach keepers and harborers, while the bite statute is limited to owners.

Prior incidents may also have produced an official label. RCW 16.08.070 classifies a dog as “dangerous” when, among other things, it has severely injured a person without provocation, and RCW 16.08.080 requires the owner, as a condition of registration, to post a $250,000 surety bond or hold liability insurance for at least that amount. Animal control records can show what the owner knew.

Police dogs and city or county claims

RCW 16.08.040(2) carves out the lawful application of a police dog, a term taken from RCW 4.24.410. That section defines a police dog as one used by a law enforcement agency, specially trained for law enforcement work and under the control of a dog handler, and lawful application as use allowed by law.

A state or local agency is not strictly liable for damages from the lawful application of a police dog, and a handler who uses the dog in the line of duty in good faith is immune from civil suit. A dog that is not used by a law enforcement agency, such as a private guard dog, does not fit the definition.

When the dog belongs to a city or county, the injured person must first present a claim to the local government’s designated agent, on the standard tort claim form or the local government’s own claim form, and then wait 60 calendar days before suing (RCW 4.96.020).

Defenses, shared fault and deadlines

Strict liability does not mean automatic payment. RCW 16.08.060 makes proof that the injured person provoked the attack a complete defense. Whether someone’s conduct amounts to provocation depends on what happened, so statements from people who saw it and any camera footage can carry real weight.

If a jury finds you partly to blame, RCW 4.22.005 cuts your award by your percentage of fault but does not wipe it out. RCW 4.22.015 counts conduct that creates strict tort liability as “fault,” so the owner’s statutory liability can be weighed against your share.

The general deadline to sue for a personal injury in Washington, which covers dog bite claims, is three years (RCW 4.16.080(2)). When the injured person is a minor, the years before age 18 generally are not counted (RCW 4.16.190).

What this means for your case

Start with two questions: did the dog bite you, and where were you when it happened? If it was a bite and you were in public or invited onto the property, RCW 16.08.040 is the starting point. If you were knocked down, or your hand went into a fenced yard, the case depends on the dog’s history and how it was controlled.

• Photograph the injuries, the location and any fence, gate or warning sign.
• Get the names of the owner, any caretaker and witnesses.
• Report the bite, then request animal control’s records on the dog, including any dangerous dog finding.
• Keep medical records and bills, and note the three-year deadline.
