Hawaii Dog Bite Laws: Liability, Dangerous Dog Rules, and Insurance

What Hawaii law expects from you as a dog owner — who pays after a bite, how a dog gets designated dangerous, and whether the state requires liability insurance. Every citation links to the official statute.

Who pays when a dog bites — the Hawaii rule

Hawaii's core statute, HRS § 663-9, reads like strict liability: an owner is liable for a bite even without proof of knowing the dog was dangerous. But the statute's case notes cite a 1986 appeals ruling that this does not create true strict liability for an ordinary bite; it just removes a victim's need to prove prior knowledge. A separate part of the statute imposes absolute liability, but only for animals already known to be dangerous, wild, or vicious, similar to a "one bite" rule. Practically, a first bite can still make you liable under negligence, but once a dog has shown dangerous tendencies, liability is harder to avoid.

Hawaii gives owners defenses under HRS § 663-9.1: unlawful trespass by the injured person, or provocation of the dog without the owner's negligence. Under HRS § 142-75, once your dog bites a person, you take on an ongoing duty to prevent a repeat, and anyone can sue to force a review of your confinement or seek the dog's removal.

How a dog gets designated dangerous

Hawaii's dangerous-dog rules sit in the criminal code, HRS §§ 711-1140 to 711-1148, added in 2024. A dog is dangerous if, without provocation, it causes a bite injury to a person or another animal (§ 711-1140); breed cannot factor into that call. An officer can declare a dog dangerous on probable cause, and the owner has 30 days to contest it.

Once declared, HRS § 711-1142 requires microchipping and registration, adult supervision indoors, a locked escape-proof kennel when unattended outside, a leash of 4 feet or less with adult supervision on the property, and a leash plus basket muzzle off the property. Owners must post a warning sign and spay or neuter the dog unless a vet objects. After 3 years of compliance and a behavior-modification program, an owner can apply to lift the designation (§ 711-1143).

Violating these rules is itself a crime and can lead to seizure of the dog. A violation causing a bite is a misdemeanor: $1,000 to $2,000 and up to 6 months in jail. A violation causing serious injury or death is a felony, 1 to 5 years in prison, with mandatory euthanasia of the dog (§ 711-1144).

Insurance requirements

Hawaii does not require liability insurance just for owning a dog, even one already declared dangerous. The requirement only appears after a conviction: under HRS § 711-1144(3), an owner convicted of negligently failing to control a dangerous dog must get liability insurance or post a bond of at least $50,000, an amount a court can raise to cover future costs.

Hawaii state law has no broader insurance mandate tied to dog ownership. Counties may add their own requirements.

Rules change at the state line — a dog that is fine at home can put you under a different liability standard on vacation. See the full 50-state table.
