Does Hawaii Follow the One Bite Rule? What Dog Bite Victims Need to Know
June 22, 2026
If you have been bitten by a dog in Hawaii, your first question is likely a practical one: can you hold the owner responsible? The answer depends on a legal framework that is more layered than what most people expect. Hawaii sits in a category of states sometimes called “mixed” dog bite law states — a place where a statute that looks like strict liability has been interpreted by courts in a way that brings it closer to the traditional one bite rule.
Understanding exactly where Hawaii stands, what you need to prove, and what defenses an owner might raise can make a real difference in how you approach a claim. This guide walks you through each piece of the framework in plain terms.
Important Note: This article is for general informational purposes only and does not constitute legal advice. If you have been bitten by a dog in Hawaii, consult a qualified Hawaii personal injury attorney to evaluate your specific situation.
Does Hawaii Follow the One Bite Rule?
Hawaii is a one bite state despite having what appears to be a strict liability statute. That distinction matters because it shapes what a bite victim must actually do to win a case in court.
Hawaii does not follow a traditional one bite rule, nor does it impose blanket strict liability in every situation. Instead, the state has adopted a modified strict liability standard that makes dog owners legally responsible for injuries caused by their dog, even if the dog has never shown signs of aggression before.
The tension between those two descriptions comes from a 1986 court decision. In that ruling, the Hawaii Court of Appeals held that section 663-9 does not establish strict liability for canine-inflicted injuries, but merely clarifies that a victim who bases a case on negligence does not have to prove scienter. Section 663-9 has been interpreted to mean that one can prove negligence without having to prove scienter — in other words, knowledge of the dog’s viciousness does not have to be proved as long as the dog owner’s conduct is shown to be unreasonable.
For a broader comparison of how other states handle this question, see how the one bite rule works in Florida or review the approach taken under the one bite rule in Washington.
How the One Bite Rule Works in Hawaii
The key statute is Hawaii Revised Statutes § 663-9. Under the statute, an owner or harborer of an animal is strictly liable for personal or property damage to any person, regardless of the animal owner’s or harborer’s lack of scienter — meaning lack of knowledge — of the vicious or dangerous propensities of the animal. In plain terms, you can be held liable even if your dog has never bitten anyone before and you had no reason to think it would.
However, courts have interpreted that language in a way that limits its reach. The Hawaii Court of Appeals held that section 663-9 does not establish strict liability for canine-inflicted injuries, but merely clarifies that a victim who bases a case on negligence does not have to prove scienter. Section 663-9 has been interpreted to mean that one can prove negligence without having to prove scienter — knowledge of the dog’s viciousness does not have to be proved as long as the dog owner’s conduct is shown to be unreasonable.
To recover for a dog bite in this state, the victim must prove scienter, negligence, or intentional injury, as in any other one bite state. That gives you three distinct legal paths, which is more than many traditional one bite states offer.
Key Insight: Hawaii’s liability framework is sometimes described as a “mixed” approach — it removes the requirement to prove prior knowledge of viciousness in negligence cases, but courts have stopped short of calling it pure strict liability. In practice, most bite victims can pursue a claim even for a first offense.
To understand how this compares with states that have cleaner strict liability rules, it helps to look at the one bite rule in New Jersey or the one bite rule in Illinois, both of which take different approaches to owner knowledge.
What Victims Must Prove Under the One Bite Rule in Hawaii
Because Hawaii’s framework gives you multiple legal theories, your path to compensation depends on which theory you rely on. Each one has its own elements.
- Scienter (prior knowledge): If the dog’s owner or harborer was aware that the dog was vicious, the dog bite victim in Hawaii can base a claim on the doctrine of scienter. This is the classic one bite theory — you show the owner already knew the dog was dangerous.
- Negligence: This state also permits a dog bite victim to recover compensation on the ground of negligence. Negligence is the lack of ordinary care — the absence of the kind of care a reasonably prudent and careful person would exercise in similar circumstances. If a person’s conduct in a given circumstance doesn’t measure up to the conduct of an ordinarily prudent and careful person, that person is negligent.
- Intentional injury: If the owner deliberately used the dog to harm you, a claim based on intentional conduct is also available.
In addition to the statutory framework, a victim may have grounds for a lawsuit if the dog owner was negligent in preventing the attack — for example, if the owner knew or should have known that the dog had aggressive tendencies but failed to take reasonable steps to prevent the attack, such as properly restraining the dog or warning others about its behavior.
For a sense of how the proof requirements compare across states, see what victims must establish under the one bite rule in Michigan and the one bite rule in Minnesota.
What Counts as Prior Knowledge in Hawaii
When a victim pursues a scienter-based claim, the central question is what the owner actually knew — and when they knew it. Hawaii courts look at the totality of the owner’s awareness of the dog’s tendencies.
Prior knowledge does not require a previous bite. A victim may have grounds for a lawsuit if the dog owner was negligent in preventing the attack. This could include situations where the owner knew or should have known that the dog had aggressive tendencies but failed to take reasonable steps to prevent the attack, such as properly restraining the dog or warning others about its behavior.
Evidence that courts and attorneys typically examine when assessing prior knowledge includes:
- Prior biting incidents, even if they did not cause serious injury
- Growling, snapping, or lunging at people or other animals
- Complaints from neighbors or prior reports to animal control
- The owner’s own statements about the dog’s temperament
- Whether the dog was kept chained, muzzled, or otherwise restrained as a precaution
Under Hawaii law, the owner of any dog that has bitten a human being has the duty to take such reasonable steps as are necessary to prevent the recurrence of such incident. That statutory duty means a prior bite creates documented, legally significant notice — and it can become a powerful piece of evidence in any subsequent claim.
Pro Tip: If you were bitten and the dog had previously snapped at or frightened someone else, gather that information early. Witness statements, animal control records, and even social media posts can help establish the owner’s prior knowledge before litigation begins.
Exceptions and Defenses to the One Bite Rule in Hawaii
Even when you can establish the owner’s knowledge or unreasonable conduct, the owner may raise defenses that reduce or eliminate their liability. Hawaii’s statute spells out the most important ones directly.
The owner or holder generally won’t be liable if (1) you were trespassing, (2) the dog bit you because it was “teased, tormented, or otherwise abused without the negligence, direction, or involvement of the owner or harborer,” or (3) the dog was defending itself or another.
The trespassing defense is codified in the statute. Any owner or harborer of an animal shall not be liable for any civil damages resulting from actions of the animal occurring in or upon the premises of the owner or harborer where the person suffering either personal or property damage as a proximate result of the actions of the animal is found by the trier of fact to have intentionally or knowingly entered or remained in or upon such premises unlawfully.
The provocation and self-defense exceptions are similarly grounded in statute. Any owner or harborer of an animal shall not be liable for any civil damages resulting from actions of the animal where the trier of fact finds that: (1) the animal caused such damage as a proximate result of being teased, tormented, or otherwise abused without the negligence, direction, or involvement of the owner or harborer; or (2) the use of the animal to cause damage to person or property was justified under chapter 703.
| Defense | What the Owner Must Show | Effect on Liability |
|---|---|---|
| Trespassing | Victim entered the property unlawfully and knowingly | Owner not liable for civil damages |
| Provocation | Dog was teased, tormented, or abused by the victim | Owner not liable if provocation was without owner’s involvement |
| Justified use / self-defense | Dog’s action was justified under HRS chapter 703 | Owner not liable for resulting damages |
| Comparative fault | Victim’s own negligence contributed to the incident | Damages reduced in proportion to victim’s share of fault |
Hawaii also applies comparative fault principles in personal injury cases. If you contributed to the incident — for example, by approaching a dog that was clearly agitated — a court may reduce your damages by the percentage of fault assigned to you.
Dog Owner Liability Beyond the One Bite Rule in Hawaii
Hawaii’s liability framework does not stop at the civil tort system. Owners face additional obligations and potential consequences under separate statutes and county ordinances.
The owner of any dog that has bitten a human being has the duty to take such reasonable steps as are necessary to prevent the recurrence of such incident. Whenever a dog has bitten a human being under circumstances for which none of the exceptions specified in section 663-9.1 apply, any person may bring an action against the owner of the dog in the district court of the judicial circuit in which the owner resides, to determine whether conditions of the treatment or confinement of the dog or other circumstances existing at the time of the bite or bites have been changed so as to remove the danger to other persons presented by the animal. The court, after hearing, may make any order it deems appropriate to prevent the recurrence of such an incident, including but not limited to the removal of the animal from the area or its destruction by its owner.
The owner of the dog shall confine or destroy the dog, and if the owner neglects or refuses to do so, the owner of the dog, in the event of any further damage being done to the person or property of any person by the dog, in addition to paying the person injured for the damage, shall pay the costs of the trial together with the penalty imposed under section 142-12, and it shall be lawful for any other person to destroy the dog.
Each county may enact and enforce ordinances regulating persons who own, harbor, or keep any dog that has bitten, injured, or maimed a person. This means that Honolulu, Maui, Hawaii County, and Kauai may each have local rules that go beyond state law — including breed-specific regulations, mandatory reporting requirements, and additional confinement orders.

What to Do After a Dog Bite in Hawaii
The steps you take in the hours and days after a dog bite directly affect both your health and your ability to pursue a legal claim. Acting methodically matters.
- Seek medical attention immediately. Even a bite that looks minor can cause infection or nerve damage. A medical record created close in time to the incident is also important evidence for any future claim.
- Identify the dog and its owner. Get the owner’s name, address, and contact information. Ask whether the dog is current on its rabies vaccination — Hawaii law requires it, and you will need that information for your physician.
- Report the bite to animal control. Filing a report creates an official record and triggers the owner’s statutory duty to take preventive steps under HRS § 142-75. It also protects other people who might encounter the same dog.
- Document everything. Photograph your injuries at each stage of healing, preserve any torn or bloodied clothing, and write down exactly what happened while the details are fresh. Note where the bite occurred and whether you had permission to be there.
- Gather witness information. Anyone who saw the incident — or who can speak to the dog’s prior behavior — may be valuable later. Get names and phone numbers before people leave the scene.
- Consult a Hawaii personal injury attorney. Hawaii has a two-year statute of limitations for personal injury claims, including dog bite cases, meaning the victim must file their lawsuit within two years of the date of the injury. If they wait too long, they may lose the right to recover compensation. An attorney can assess which legal theory — scienter, negligence, or intentional injury — fits your facts and help you preserve evidence before it disappears.
Common Mistake: Some bite victims assume that because the dog had no prior history of aggression, there is no viable claim. Under Hawaii’s modified liability standard, prior behavior is not a prerequisite for a successful negligence claim. What matters is whether the owner acted reasonably under the circumstances.
If you want to understand how the legal process compares across states, the one bite rule in New York, the one bite rule in Arizona, and the one bite rule in Colorado each illustrate how differently states balance owner and victim rights. You can also review the one bite rule in Missouri and the one bite rule in Tennessee for additional context on how traditional one bite states operate in practice.
Hawaii’s dog bite law rewards victims who understand its nuances. The statute removes the barrier of proving the owner’s prior knowledge in negligence cases, while still giving you the option to pursue a scienter-based claim if that evidence exists. Knowing which path fits your situation — and acting within the two-year window — is the foundation of any successful claim.
