Dangerous Dog Declaration in Hawaii: What Every Owner Needs to Know
June 24, 2026
A dangerous dog declaration in Hawaii is a serious legal matter — one that can affect your dog’s future, your finances, and your standing with local animal control authorities. Whether your dog has been involved in an incident or you simply want to understand the rules before a problem arises, knowing how Hawaii law works puts you in a far stronger position.
Hawaii’s framework for dangerous dogs was significantly expanded under Act 224 (House Bill 2058), which amended Chapter 711 of the Hawaii Revised Statutes (HRS) to establish a statewide process for declaring, managing, and rescinding dangerous dog designations. This guide walks you through every stage of that process so you know exactly what to expect.
Important Note: Hawaii’s dangerous dog law operates at both the state level (HRS Chapter 711) and the county level. Honolulu, Hawaii County, Maui County, and Kauai County each have their own animal control agencies and may apply additional local rules. Always confirm the specific procedures with your county’s animal control authority.
What Makes a Dog “Dangerous” Under Hawaii Law
Hawaii law uses a behavior-based definition rather than a breed-based one. Under HRS Chapter 711, a “dangerous dog” means any dog that, without provocation, causes a bite injury to a person or another animal. A bite injury is defined specifically — it means any contact between an animal’s mouth and teeth and the skin of a bite victim that causes visible trauma, such as a puncture wound, laceration, or other piercing of the skin.
One of the most important protections built into Hawaii’s statute is that a dog’s breed shall not be considered in determining whether it is dangerous. This means no dog can be labeled dangerous simply because of its breed or appearance. The focus is entirely on documented behavior.
The provocation element matters a great deal. If your dog bit someone who was trespassing, taunting the animal, or otherwise provoking an attack, that context is legally relevant and can affect whether a declaration is issued or upheld. You should document any provocation evidence as soon as an incident occurs.
It is also worth understanding that Hawaii County’s own ordinances (Hawaii County Code Chapter 4) address related conduct, such as negligently failing to take reasonable measures to prevent a dog from attacking, without provocation, a person or animal, where the attack results in the maiming, causing of serious injury to, or destruction of an animal. This conduct can trigger both civil and criminal consequences separate from the dangerous dog declaration itself.

Who Can File a Dangerous Dog Complaint in Hawaii
A dangerous dog declaration does not always begin with a formal complaint from a private citizen. An officer may find and declare a dog to be a dangerous dog if the officer has probable cause to believe that the dog falls within the definition of “dangerous dog.” The declaration shall be based upon: (1) the written complaint of a person who is willing to testify that the dog has acted in a manner that causes it to fall within the definition; (2) actions of the dog witnessed by an officer; or (3) other substantial evidence admissible in court.
In practice, this means the process can start in three distinct ways. A neighbor, pedestrian, or other witness can file a written complaint — but only if they are willing to testify to what they saw. An animal control officer or police officer can also initiate a declaration based on their own direct observation, or on other substantial evidence such as veterinary records, photographs, or prior incident reports.
On Oahu, for non-emergency concerns or to file a report, you can contact the Hawaiian Humane Society’s Field Services Dispatch at (808) 356-2250 or complete a Citizen Complaint form. In Hawaii County, effective July 1, 2023, the County of Hawaii created an Animal Control and Protection Agency (ACPA), and the county — not the police department — now houses and performs animal control services island-wide.
For animal emergencies on the Big Island, you can call dispatch at (808) 935-3311, or for lost/found pets and non-emergencies, contact the Hawaii County Animal Control and Protection Agency at (808) 327-3558.
Pro Tip: If someone files a complaint against your dog, ask the animal control authority whether the complainant has agreed to testify. Under Hawaii law, a written complaint only qualifies as a basis for a declaration if the complainant is willing to appear and give testimony.
How the Dangerous Dog Declaration Process Works in Hawaii
Once an officer determines there is probable cause, the declaration process follows a specific legal sequence. The declaration shall be in writing and shall be served by the officer upon the owner of the dangerous dog, if known, using one of the following methods: certified mail to the owner’s last known address. Other service methods may also apply depending on the county’s procedures.
On Oahu, the Honolulu Police Department plays a direct role in the early stages. The officer shall initiate a dangerous dog report and forward a copy to the Hawaiian Humane Society (HHS) via the case reporting system. Officers responding to dangerous dog complaints shall make every effort to ensure that the dog is no longer a threat to the public, which may include calling HHS personnel to the scene.
Depending on the severity of the incident, the dog may be impounded immediately. Impoundment includes securing the dangerous dog within the dog owner’s property, having the owner take the dog to a licensed veterinarian facility or commercial kennel for boarding, or having the Hawaiian Humane Society respond to take custody of the animal.
If the dog remains at the owner’s property during the process, strict containment rules apply. When indoors or outdoors on the owner’s premises and attended, the dog shall be under the control of a person 18 years of age or older. When outdoors and unattended, the dog shall be kept within a locked, fenced, or walled area from which it cannot escape, or confined to an escape-proof kennel.

Your Rights as a Dog Owner During the Process in Hawaii
Hawaii law gives you meaningful procedural rights once a declaration is served. The owner of a dog declared to be a dangerous dog may initiate a contested case with the declarant officer’s department or agency within thirty days following the service date of the declaration. This thirty-day window is critical — missing it can forfeit your right to formally challenge the declaration at the administrative level.
The American Kennel Club has been clear about the importance of these protections. The AKC believes that governments must protect constitutional rights and privileges of dog owners. Owners must be afforded substantive and procedural due process protections, and must not be permanently or unreasonably deprived of the property interests they have in their animals without first pleading guilty to, being found guilty of, or pleading “no contest” to animal-related criminal charges.
During the process, you have the right to present evidence, including witness statements, veterinary records, photographs, and any documentation that supports a provocation defense. You can also argue that the incident did not meet the legal definition of a “bite injury” as defined under the statute. Consulting an attorney who handles animal law or administrative proceedings in Hawaii is strongly advisable if a declaration has been served on you.
| Right | What It Means in Practice |
|---|---|
| Right to written notice | Declaration must be served in writing via certified mail or other approved method |
| Right to contest | You have 30 days from service date to initiate a contested case hearing |
| Right to present evidence | You may submit witness testimony, photos, vet records, and provocation evidence |
| Breed protection | Your dog’s breed cannot be used as a factor in the determination |
| Civil action preserved | A dangerous dog declaration does not prevent you from pursuing civil remedies |

What Happens After a Dog Is Declared Dangerous in Hawaii
Once a dangerous dog declaration is finalized, you take on a set of ongoing legal obligations. The owner of a dog declared to be a dangerous dog shall provide the owner’s name, address, and telephone number to the animal control authority, as well as the location at which the dangerous dog is currently kept. This registration requirement keeps the animal control authority informed of the dog’s whereabouts at all times.
Beyond registration, Hawaii law imposes several management requirements. Legal requirements of an owner of a dangerous dog include spaying or neutering the dog unless medically contraindicated. Owners must also maintain proper containment at all times and comply with any additional conditions set by the animal control authority.
Impoundment costs are the owner’s financial responsibility. The law establishes grounds for the impoundment of a dangerous dog and requires the owner to pay for impoundment, care, and provision costs, with automatic forfeiture if an owner is unable to pay assessed costs.
The declaration also has consequences under Hawaii’s civil liability law. Under HRS section 663-9, the owner or harborer of an animal, if the animal proximately causes either personal or property damage to any person, shall be liable in damages to the person injured regardless of the animal owner’s or harborer’s lack of scienter of the vicious or dangerous propensities of the animal. A formal declaration makes it significantly harder to argue you were unaware of your dog’s dangerous tendencies in any future civil lawsuit.

How to Contest a Dangerous Dog Declaration in Hawaii
Contesting a dangerous dog declaration in Hawaii follows the state’s administrative contested case process. You must act quickly — the thirty-day window from the date the declaration was served is a hard deadline. Once you file for a contested case hearing, the matter moves to the relevant county department or agency for a formal review.
At the hearing, the burden is on the officer or agency to demonstrate that probable cause exists and that the evidence supports the declaration. Your role is to challenge that evidence and present your own. Strong defenses typically include:
- Evidence that the dog was provoked before the incident occurred
- Witness testimony contradicting the complainant’s account
- Veterinary or behavioral records showing the dog’s history of non-aggression
- Documentation that the complainant is unwilling or unable to testify
- Evidence that the injury did not meet the legal definition of a “bite injury”
If the administrative hearing does not resolve the matter in your favor, you may have the option to appeal to the circuit court. Hawaii’s administrative procedure law governs this process, and the specific rules vary by county. An attorney experienced in Hawaii animal law or administrative appeals can help you navigate both levels of the process.
If the declaration is ultimately upheld, the path forward is not necessarily permanent. The owner of a dangerous dog may apply to the animal control authority to have the declaration rescinded after three years if: (1) the owner and dangerous dog have no subsequent violations; (2) the owner has complied with all provisions for a period of three years; and (3) the owner provides proof of the dangerous dog’s successful completion of a behavior modification or management program administered by an animal trainer or behaviorist certified by a nationally recognized organization.
If the animal control authority finds that the owner and dangerous dog have complied with all of the requirements and the owner has provided sufficient evidence that the dangerous dog’s behavior has changed, the animal control authority shall rescind the declaration.
Pro Tip: Start documenting your dog’s behavior and compliance with all dangerous dog requirements from day one. Detailed records of training sessions, vet visits, and containment measures will be your most valuable asset when you apply for rescission after three years.

Penalties for Violating Dangerous Dog Requirements in Hawaii
Failing to comply with dangerous dog requirements in Hawaii carries serious consequences that escalate with the severity of the violation. The law creates both administrative penalties and criminal offenses depending on what occurred.
At the county level, Hawaii County’s ordinances treat negligent failure to control a dangerous dog as a criminal matter. Police investigate such cases as negligent failure to control a dangerous dog, and failure to take reasonable measures to prevent an unprovoked dog attack resulting in serious injury or death is a felony under county law. If convicted, dog owners could face up to a $25,000 fine and up to 10 years in prison.
Upon finding probable cause to believe that there has been a violation, a police officer may arrest or issue a summons and citation to the dog’s owner, or both. In addition to arresting or issuing a summons and citation to the owner, a police officer shall have the dog seized and impounded by animal control officers.
The table below summarizes the key penalty categories under Hawaii’s dangerous dog framework:
| Violation Type | Potential Consequence |
|---|---|
| Failure to register dog with animal control authority | Administrative violation; possible citation |
| Failure to contain dangerous dog properly | Citation, impoundment of dog |
| Failure to pay impoundment/care costs | Automatic forfeiture of the dog |
| Negligent failure to control (resulting in serious injury) | Felony charge; fines and imprisonment |
| Negligent failure to control (resulting in death) | Felony charge; up to $25,000 fine and up to 10 years imprisonment (Hawaii County) |
Beyond criminal penalties, a civil lawsuit from the injured party is also a real possibility. Under HRS section 663-9, the owner or harborer of an animal is liable in damages to the person injured if the animal proximately causes either personal or property damage to any person. Once a dog has been formally declared dangerous, defending against a civil claim becomes substantially harder because prior knowledge of the dog’s propensities is already established on the record.
Understanding your obligations thoroughly — and meeting them consistently — is the most effective way to protect both your dog and yourself from the most serious consequences Hawaii law allows.
