Strict Liability Dog Bite States: Which States, and What It Means

As of October 2026, 22 states have a statute that makes a dog’s owner liable for a bite or attack without proof that the owner knew the dog was dangerous. Another 16 jurisdictions have a statute that does the same only in some situations, and the remaining 13 rely on the one-bite rule and negligence. The full list, with each statute, is below.

“Strict liability” does not mean the owner always pays. Every statute has limits: what kind of injury it covers, where the victim was, who counts as the owner, and defenses such as trespass and provocation. Those limits decide most disputed cases.

What strict liability means for a dog bite

Strict liability removes the hardest element of a dog bite claim: proof that the owner knew, or should have known, that the dog was dangerous. Under the old common-law rule, a first bite was often free, because the owner had no warning. A strict-liability statute makes the dog’s history irrelevant.

Florida’s statute is typical. The owner of a dog that bites a person in a public place, or lawfully on private property, is liable regardless of the dog’s former viciousness or the owner’s knowledge of it ⁴. California’s § 3342, enacted in 1931, uses nearly the same words ¹, as do the statutes of Michigan ⁷, New Jersey ⁹ and Arizona ²⁴.

The injured person still has to prove some things. In New Jersey, the Model Jury Charge lists three: the defendant owned the dog, the plaintiff was lawfully present, and the dog bit the plaintiff ⁹. Damages must still be proved too. Strict liability also does not require the owner to have been careless: an owner who kept the dog leashed and behind a fence is liable all the same.

Which states are strict liability dog bite states?

These 22 states have a statute that applies to bites or attacks generally, wherever the statute’s place rule is met. The “Covers” column shows whether it reaches only bites or any injury the dog causes.

The rule in each state is on its page, with the defenses and the deadline to sue. If your state is not in this table or the next one, see the one-bite rule guide, and dog bite laws by state for all 51 jurisdictions on one page.

Bites only, or any injury?

Of the jurisdictions with a statute, 10 limit it to bites. The rest cover any injury the dog causes, which matters when a dog knocks someone down, causes a fall, or chases a cyclist into traffic.

California ¹, Florida ⁴, Michigan ⁷, New Jersey ⁹, Arizona ²⁴ and Washington ²¹ are bite statutes. In those states, a non-bite injury needs a common-law claim: proof that the owner knew of the dog’s dangerous tendency, or was negligent. California’s courts let those claims run alongside § 3342 ².

Ohio makes the owner, keeper or harborer liable for “any injury, death, or loss” the dog causes ⁵. Connecticut ¹¹, Massachusetts ¹² and Wisconsin ¹³ reach any damage the dog does. Iowa covers a dog “attacking or attempting to bite” a person ¹⁶. Nebraska covers bites, and also a dog that kills, wounds, injures, worries or chases a person, though its Supreme Court limits that second part to aggressive acts, not play ¹⁸.

Where the bite happened

Most strict statutes protect only people in a public place or lawfully on private property. That language, in California, Florida, Michigan, New Jersey, Arizona, Washington and others, is a built-in trespass exception ^{1 4 7 9 24 21}.

“Lawfully” usually includes the owner’s own property. A guest invited expressly or by implication qualifies, and so does a person there to perform a duty under state or federal law or postal regulations, such as a mail carrier ^{1 4}. Washington adds a twist: consent to enter is not presumed if the property is fenced or reasonably posted ⁴³.

Other statutes have no place limit. Connecticut, Massachusetts, Ohio, Wisconsin, Utah and Iowa apply wherever the injury happened, subject to their own exceptions ^{11 12 5 13 19 16}. Illinois protects a person acting peaceably in any place where they may lawfully be ²³, and Minnesota uses almost the same words ²⁶.

What strict liability does not cover: defenses

The defenses are written into each statute, and courts read them closely. The common ones are:

1. Trespass. Bite statutes exclude people who were not lawfully present ^{1 21}. Connecticut and Massachusetts bar a person “committing a trespass or other tort” ^{11 12}. Ohio’s trespass exception reaches only criminal trespass or another crime on the owner’s property ⁵. Utah added a narrow criminal-trespasser exception in 2025, for a dog fenced in on the owner’s land ^{19 20}.
2. Provocation. Washington makes provocation “a complete defense” ²². Michigan’s statute covers only bites “without provocation,” and its Court of Appeals held in Brans v. Extrom (2005) that an unintentional act can be provocation ⁸. In Arizona, provocation is the only defense the courts allow; Massey v. Colaric (1986) rejected assumption of risk ²⁵.
3. Teasing, tormenting or abusing the dog. Ohio, Connecticut and Massachusetts use this phrase ^{5 11 12}. In Connecticut and Massachusetts, a child under seven is presumed not to have teased the dog ^{11 12}.
4. The victim’s own unlawful act. In Iowa this is the only defense: no liability if the injured person was doing an unlawful act that directly contributed to the injury ¹⁶.
5. Police and military dogs. Several statutes exempt a government agency whose dog bites a suspect under a written policy, including California’s since 1988 ¹ and Nebraska’s since 2009 ¹⁸. See police dog bites.

Courts disagree on defenses the statute does not mention. The Supreme Court of California held in 1959 that § 3342 did not remove assumption of risk ³. The Supreme Court of Ohio held in Pulley v. Malek (1986) that only the statute’s own exceptions can defeat a claim ⁶. For how each defense works, including children and provocation, see provocation and trespass.

Veterinarians, groomers and sitters

Strict liability usually falls on the owner, and some states exclude people who were handling the dog. California’s veterinarian’s rule bars a vet or vet assistant from using § 3342, and in Priebe v. Nelson (2006) the state Supreme Court applied it to a kennel worker ². Other states refuse that rule: Iowa in Collins v. Kenealy (1992), for a groomer ¹⁷, and New Jersey in Goldhagen v. Pasmowitz (2021), where the worker’s experience goes to comparative fault instead ¹⁰.

Who counts as the owner varies. Ohio, Connecticut, Massachusetts, Illinois and Minnesota reach keepers or harborers ^{5 11 12 23 26}. New Jersey’s and Louisiana’s statutes bind only the owner ^{9 14}. Dog bite at work covers workers’ claims in detail.

Does your own fault reduce a strict-liability award?

In most strict states it does. Florida’s § 767.04 reduces the owner’s liability by the bitten person’s percentage of negligence ⁴, and Utah’s statute sets damages under its comparative-negligence law ¹⁹. Wisconsin’s § 174.02 is expressly subject to comparative negligence ¹³.

A few states keep the statute absolute. The Minnesota Supreme Court treats § 347.22 liability as absolute, with the victim’s comparative fault beside the point ²⁷. Massachusetts handles the victim’s conduct through the statute’s own exceptions ¹². Each state’s shared-fault rule is in the provocation and trespass guide’s fault table and on the state pages.

Louisiana: strict liability with a condition

Louisiana Civil Code art. 2321 says the owner “is strictly liable” for injuries the dog caused “and which the owner could have prevented and which did not result from the injured person’s provocation of the dog” ¹⁴. The Louisiana Supreme Court requires proof that the dog posed an unreasonable risk of harm ¹⁵. In Pepper v. Triplet (2004), a neighbor who let himself into a fenced yard lost, because a securely confined dog posed no such risk ¹⁵.

Partial strict-liability states

These 16 jurisdictions have a statute that removes the knowledge requirement only in some situations, or only for some damages. Outside those situations, the one-bite rule and negligence apply.

The limits fall into a few groups:

• Only some damages. Pennsylvania makes the owner or keeper pay the victim’s medical costs, with no knowledge requirement; other losses need a negligence or scienter claim ²⁸. Colorado allows economic damages, and only for serious bodily injury or death ²⁹. New York makes the owner of a dog already found dangerous strictly liable for medical costs ³².
• Only off the owner’s property. Maine applies strict liability when the victim was not on the owner’s or keeper’s premises ³⁰, and Rhode Island when the victim was on the highway or outside the owner’s enclosure ³¹. Tennessee requires proof of knowledge for bites on the owner’s residential or farm property ³⁹.
• Only a dog at large. In D.C., the owner’s lack of knowledge is no defense when the dog injured someone while at large, but negligence must still be shown ⁴⁰. Maryland makes the owner liable for a dog running at large and presumes, rebuttably, that the owner knew of a dangerous propensity in any injury case ⁴¹.
• Only in town. Montana’s bite statute applies within incorporated cities and towns ³³. Oklahoma’s excludes rural areas and towns without city or village mail delivery ^{34 35}.
• A leash ordinance. In Georgia, proof that the dog violated a local leash ordinance replaces proof that the owner knew the dog was dangerous ⁴².

States with no strict-liability statute

The other 13 jurisdictions have no statute that removes the knowledge requirement. Texas is one: under Marshall v. Ranne (1974), the owner is strictly liable only if the dog had dangerous tendencies abnormal to its class and the owner knew or should have known it ³⁸. Otherwise the victim must prove negligence.

Hawaii is a special case. Its 1980 statute says the owner is liable “regardless of” lack of knowledge ³⁶, but its courts hold that the victim must still prove negligence, so the site classes it with the one-bite states ³⁷. The one-bite rule guide lists all of them.

How to use this list

1. Find your state’s row. The tables above show whether a statute exists and what it covers. The states index links every state page.
2. Check the place and injury rules. Note whether the statute reaches bites only, and whether you were in a public place or lawfully on the property.
3. Read the defenses. Each state page lists the statute’s exceptions and the leading cases.
4. Note the deadline. The statute of limitations guide has every state’s filing deadline, including the rules for children.
5. Run the checker. The claim checker applies your state’s rule to your facts. It gives information, not legal advice.

Questions

Is California a strict liability dog bite state?

Yes. Civil Code § 3342 makes the owner liable for a bite in a public place or while the victim was lawfully on private property, including the owner's, regardless of the dog's past behavior or the owner's knowledge¹. It covers bites only; other injuries need a common-law claim².

Is Texas a strict liability state for dog bites?

No. Texas has no civil dog bite statute. Under Marshall v. Ranne (1974), an owner is strictly liable only if the dog had dangerous tendencies abnormal to its class and the owner knew or should have known it; otherwise the victim must prove negligence³⁸.

Does strict liability mean I automatically win a dog bite case?

No. You still have to prove the defendant owned (or, in some states, kept) the dog, that the dog caused the injury, and your damages. The statute's own exceptions, such as trespass or provocation, can defeat the claim, and in most strict states your share of fault reduces the award⁵²¹²².

Does strict liability apply if a dog knocks someone down without biting?

Only in states whose statute covers any injury. Ohio's, for example, covers any injury the dog causes⁵. Washington's covers bites, so a knock-down there needs proof of fault²¹.

Can a dog owner be strictly liable for a dog that bit for the first time?

Yes. That is the point of the statutes. Florida's says the owner is liable regardless of the dog's former viciousness or the owner's knowledge of it⁴, and Michigan's applies whatever the dog's history or the owner's knowledge⁷.
