Short Answer
For most adult dog bite victims in Washington, the statute of limitations is three years from the date of the injury, under RCW 4.16.080(2). To preserve your claim, you have to formally file a lawsuit before that three-year window closes. Notifying the insurance company or trading demand letters does not count. If you miss the deadline, you are permanently barred from recovering. There’s an important exception for children: under RCW 4.16.190, the clock is tolled for victims under 18, meaning it doesn’t start running until their 18th birthday. Three years can feel like plenty of time, but waiting damages claims in practice. Evidence like animal control files, photos, medical records, and camera footage disappears long before the legal deadline.
Detailed Explanation
Relevant Washington Law
The general deadline for a personal injury claim, including a dog bite, is three years from the date of injury, set by RCW 4.16.080(2).
For adults, the requirement is specific: you must file a lawsuit in court within those three years. Sending the insurer a demand, opening a claim, or negotiating is not enough. If the three years pass without a filed suit, the claim is gone, regardless of how strong it was.
The Exception for Minors
Children get more time. Under RCW 4.16.190, the three-year clock is tolled for a victim who is under 18 at the time of the bite. The clock doesn’t begin until the child turns 18.
In practical terms, that gives an injured child until their 21st birthday to file. A child bitten at age seven would have a preserved right to sue for years past the incident.
This tolling rule exists for good reason. Children’s injuries, especially scarring, take time to reveal their permanent shape, and the law doesn’t force a family to resolve a claim before the long-term impact is known.
How the Deadline Affects Strategy
Three years sounds generous. It rarely is, for one reason: evidence ages faster than the deadline.
The proof that wins dog bite cases tends to be perishable:
- Animal control investigation files, which agencies eventually purge.
- Medical records and photographs of the wound as it heals.
- Security or doorbell camera footage, often overwritten within weeks.
- Witness memories, which fade.
A claim filed at the last legal moment can be far weaker than the same claim worked up early, simply because the supporting evidence is gone.
Practical Considerations
- Treat the three-year deadline as an outer limit, not a target.
- Secure animal control records and camera footage quickly.
- Photograph injuries throughout the healing process.
- For a child’s injury, don’t assume the extra time means you should wait indefinitely. Scar maturation takes 12 to 18 months, but evidence of the attack still degrades on its own schedule.
When to Contact a Lawyer
Because filing requirements are strict and evidence is perishable, the safest move is to consult an attorney well before the deadline approaches. If you’re getting close to three years and haven’t filed suit, that’s urgent. An attorney can make sure a lawsuit is filed in time and that the evidence is preserved while it still exists.
