California is one of the most protective states in the country for dog bite victims. An owner is liable for the first bite, whether or not the dog had ever shown aggression before. But the statute has limits that matter, the filing deadline is shorter than most people assume, and injuries that are not bites are handled under an entirely different body of law.
This guide covers what the law actually says, what defenses an insurer will raise, and what has to happen before a deadline closes your claim.
Is California a strict liability state for dog bites?
Yes. California Civil Code section 3342(a) makes a dog owner liable for damages suffered by any person bitten in a public place, or lawfully in a private place, “regardless of the former viciousness of the dog or the owner’s knowledge of such viciousness.”
That last clause is what makes California a strict liability state. You do not have to prove the owner was careless. You do not have to prove the dog had bitten anyone before. You do not have to prove the owner knew the dog was dangerous. If the dog bit you and you were lawfully where you were, liability attaches.
There is no “one bite rule” for bites in California. In states that follow that rule, an owner escapes liability the first time because they had no notice the dog was dangerous. Section 3342 abolishes that for bite cases. The first bite counts.
The statute also defines who is lawfully on private property: a person is there lawfully when performing a duty imposed by state law or United States postal regulations, or when present on the express or implied invitation of the owner. That covers mail carriers, delivery drivers, meter readers, and invited guests.
What counts as a “bite”? (It does not require broken skin)
This is worth knowing because insurers get it wrong, and sometimes deliberately.
In Johnson v. McMahan (1998) 68 Cal.App.4th 173, a man was on a ladder repairing a swamp cooler when the homeowners’ German Shepherd seized his leg through his jeans. He fell and was injured. His skin was never broken. The Court of Appeal held section 3342 still applied, reasoning that nothing in the statute requires a puncture or a tearing away. The court put it plainly: “The word ‘bite’ (as opposed, for example, to the phrase ‘bit off’) does not require a puncture or tearing away.”
So if a dog seized you with its teeth and you were hurt, that is a bite for purposes of section 3342 even if there is no wound to photograph.
One trap to watch. Penal Code section 398, which requires a dog owner to give you their contact information after a bite, contains its own definition saying the skin must be broken. That definition is expressly limited “for purposes of this section.” It governs that criminal infraction only. It does not define “bitten” under Civil Code section 3342, and an adjuster who cites it to deny your claim is misapplying the law.
How long do I have to file a dog bite lawsuit in California?
Two years from the date of the bite, under Code of Civil Procedure section 335.1, which sets a two-year limit for “an action for assault, battery, or injury to, or for the death of, an individual caused by the wrongful act or neglect of another.”
That is the general rule. Several exceptions can shorten or extend it dramatically, and getting this wrong ends a case before it starts.
If the victim is a child
Code of Civil Procedure section 352(a) stops the clock during minority. A child bitten by a privately owned dog has two years from their eighteenth birthday, meaning the deadline falls on their twentieth. Parents often assume the claim has expired long before it has.
If the dog belongs to a city, county, or other public agency
This is the deadline that catches people. Before you can sue a public entity, you must present a written government claim under Government Code section 911.2 — and the deadline is six months from accrual, not two years. Miss it and the claim is generally barred.
After the entity rejects the claim in writing, Government Code section 945.6 gives you only six months from the date that rejection notice is delivered or mailed to file suit. In a government case the entire matter can be time-barred in well under a year.
And critically: the tolling for minors does not apply here. Section 352(b) expressly excludes claims governed by the Government Claims Act. A child bitten by a police dog does not get to wait until eighteen. There is a late-claim procedure, but it should never be relied on as a plan.
If you did not realize you were injured right away
The general accrual rules, including delayed discovery, can apply. This comes up with infections and nerve damage that surface later. It is fact-specific and worth a conversation rather than an assumption.
The practical takeaway: if there is any chance a public agency owned or handled the dog, treat the deadline as six months and act immediately.
What if the dog knocked me down or scratched me instead of biting?
Section 3342 reaches bites only. A dog that jumps up and knocks someone off their feet, or scratches them, falls outside the strict liability statute. That does not mean there is no case — it means the theory changes.
Negligence
In Drake v. Dean (1993) 15 Cal.App.4th 915, a large dog tethered on a long guy wire jumped on a woman in a driveway and knocked her down, breaking her hip. No bite. The Court of Appeal held the trial court erred in refusing to instruct the jury on negligence, and made the key point: negligence does not require proof of prior dangerous propensities. It turns on foreseeability — whether the owner exercised reasonable care given the characteristics of the animal.
Common law strict liability
A separate theory applies where the owner knew or should have known the animal had an unusually dangerous tendency. The victim must prove the defendant owned, kept, or controlled the animal; that it had an unusually dangerous nature; that the owner knew or should have known before the injury; and that the dangerous nature was a substantial factor in causing harm. This is the historical “one bite” rule, and it survives in California for non-bite injuries — though a prior bite is not required, only a known propensity.
Negligence per se
Violating a local leash ordinance, or the confinement requirements that attach to a dog already designated potentially dangerous, can establish negligence through the violation itself.
So the accurate statement is this: California is not a “one bite” state. For bites, liability is strict from the first incident. For other injuries, a victim can still recover through negligence, which requires no prior knowledge at all.
What defenses will the insurance company raise?
Trespassing
Section 3342 protects a person bitten in a public place or lawfully on private property. Someone bitten while trespassing falls outside the statute. Note that lawful presence includes implied invitation, so a delivery driver walking up a front path is not a trespasser.
Provocation
Teasing, tormenting, or hurting a dog before it bites is a defense. But provocation is a question of degree and of what the victim actually did — not what the owner says happened. In California it usually reduces recovery rather than eliminating it.
Assumption of risk — the veterinarian’s rule
In Priebe v. Nelson (2006) 39 Cal.4th 1112, the California Supreme Court held that a kennel worker bitten by a boarded pit bull could not bring a strict liability claim under section 3342. The doctrine of primary assumption of risk — the veterinarian’s rule — barred it, because the risk of being bitten is a hazard endemic to that occupation.
The rule has a limit worth knowing. The Court preserved a common law claim where the owner knew the dog had bitten before and did not tell the kennel. In Priebe itself the dog had been involved in a fight a year earlier and the owner said nothing. A professional who is not warned has not assumed an unknown risk.
Police and military dogs
Section 3342(b) shields a governmental agency — not a private owner — where the dog was defending itself from provocation or assisting an officer in an arrest, a criminal investigation, execution of a warrant, or the defense of a person.
Two limits do real work here. Subdivision (c) removes the immunity entirely if the person bitten was a bystander: not a party to, participant in, or even suspected participant in the conduct that prompted the dog’s use. And subdivision (d) makes the immunity conditional on the agency having adopted a written policy on appropriate use of the dog. No written policy, no immunity — which makes that policy the first thing to request.
Does it hurt my claim if I was partly at fault?
It reduces recovery. It does not eliminate it.
California follows pure comparative negligence, adopted in Li v. Yellow Cab Co. (1975) 13 Cal.3d 804. The Supreme Court replaced the old all-or-nothing contributory negligence rule with a system in which damages are “diminished in proportion to the amount of negligence attributable to the person recovering.”
Pure means there is no cutoff. A victim found 80 percent at fault still recovers 20 percent of their damages. Many states bar recovery at 50 or 51 percent; California does not. So when an adjuster suggests you were partly responsible and therefore have no claim, that is not the law.
Dangerous and vicious dog designations
Separate from your injury claim, California has an administrative scheme for classifying dogs. It is set out in Food and Agricultural Code sections 31601 through 31683, and it matters to your case because a prior designation is powerful evidence.
| Designation | What triggers it | What follows |
|---|---|---|
| Potentially dangerous § 31602 | Unprovoked, twice in 36 months, forcing someone off the owner’s property to take defensive action; or one unprovoked bite causing an injury less severe than § 31604; or twice in 36 months attacking a domestic animal off the property | Must be licensed and vaccinated; kept indoors or in a secure fenced yard children cannot enter; leashed and under adult control off the property; owner must notify animal control within two working days of death, sale, or move |
| Vicious § 31603 | Unprovoked, aggressive infliction of severe injury on or killing of a human being; or a listed potentially dangerous dog that keeps offending after notice | May be destroyed if release would create a significant threat; the court must impose conditions of ownership; the owner may be barred from owning any dog for up to three years |
“Severe injury” is defined at section 31604 as “any physical injury to a human being that results in muscle tears or disfiguring lacerations or requires multiple sutures or corrective or cosmetic surgery.” That definition is the hinge between the two categories.
A designation is made by petition to the superior court under section 31621. It is a limited civil case, the hearing is open to the public, there is no jury, and the standard is a preponderance of the evidence. Cities and counties may run their own administrative hearings instead.
Section 31644 provides that a potentially dangerous dog comes off the list after 36 months without a repeat incident, and may be removed sooner if the owner shows that training or changed circumstances have reduced the risk.
One point often stated incorrectly: section 31683 lets a city or county adopt a stricter program than the state scheme, but it expressly provides that no program regulating any dog shall be specific as to breed, apart from spay and neuter programs permitted under Health and Safety Code section 122331. California does not permit breed bans.
Can I sue the landlord if the dog belonged to a tenant?
Sometimes — and this is the avenue most often missed, particularly where the dog owner has no insurance and no assets.
Uccello v. Laudenslayer (1975) 44 Cal.App.3d 504 involved a five-year-old girl attacked by a tenant’s German Shepherd. The landlord knew about the dog, had seen it during inspections, had permitted it, and the tenancy was month-to-month. The Court of Appeal held a landlord can owe a duty of care, but drew the line carefully: “A duty of care may not be imposed on a landlord without proof that he knew of the dog and its dangerous propensities… actual knowledge and not mere constructive knowledge is required.”
The court also made clear there is “no duty to inspect the premises for the purpose of discovering the existence of a tenant’s dangerous animal.” The duty arises only when the landlord has actual knowledge of the animal combined with the power to have it removed — for example, the ability to terminate the tenancy.
So a claim against a landlord requires proof of actual knowledge of the dog’s dangerous propensities, the practical power to do something about it, a failure to exercise ordinary care, and resulting injury. It is a negligence claim, not strict liability — section 3342 applies to the dog’s owner.
Criminal exposure for the owner
A dog bite can carry criminal consequences alongside the civil claim.
- Penal Code section 398 requires an owner who knows or should know their animal bit someone to provide their name, address, telephone number, and the animal’s license tag number within 48 hours, along with vaccination status. Violation is an infraction carrying a fine of up to $100. If the owner refused to identify themselves at the scene, this is the provision that was broken.
- Penal Code section 399 applies where an owner who knows an animal’s dangerous propensities lets it go at large or fails to keep it with ordinary care, and it kills or seriously injures someone who took reasonable precautions. Subdivision (a), for a death, is a felony; subdivision (b), for serious bodily injury, may be charged as a misdemeanor or a felony.
- Penal Code section 399.5 reaches dogs trained to fight, attack, or kill, where the dog bites on two separate occasions or once causing substantial physical injury and the owner knew or should have known of the danger. It does not apply to bites on trespassers, to people who provoked the dog, or to police and military dogs at work.
What compensation is available?
- Medical expenses — emergency treatment, surgery, wound revision, infection care, rabies prophylaxis, and future procedures
- Lost income and, in serious cases, reduced earning capacity
- Pain and suffering
- Emotional distress — post-traumatic stress and lasting fear of dogs are common and compensable, particularly in children
- Scarring and disfigurement — often the largest component in facial injuries, and typically the element insurers value lowest
- Future reconstructive or cosmetic surgery, which for a growing child may mean procedures staged over years
Most dog bite claims are paid by the owner’s homeowners or renters policy. Coverage limits, and any breed exclusion in the policy, often shape the case more than liability does.
What to do after a dog bite
- Get medical care immediately. Dog bites carry a high infection risk, and a puncture that looks minor can involve deep tissue damage. For step-by-step triage of a small bite, see our guide to what to do after a minor dog bite in California.
- Get the owner’s information. Name, address, phone, and the dog’s license tag number — Penal Code section 398 requires it within 48 hours.
- Report the bite to animal control. This creates the official record, starts any dangerous-dog process, and preserves the dog’s history.
- Photograph everything — the wounds before they heal and again as they heal, the location, and the dog if you can do it safely.
- Get witness names. Provocation is the most common defense, and a neutral witness usually settles it.
- Do not give a recorded statement to the owner’s insurer before speaking with a lawyer.
- Note whether a public agency was involved. If so, the six-month claim deadline is already running.
Frequently asked questions about California dog bite law
Is California a one bite state?
No. Civil Code section 3342 imposes strict liability on the owner for the first bite, regardless of whether the dog had ever bitten before or whether the owner knew it was dangerous. The knowledge requirement survives only for injuries that are not bites, and even there a victim can proceed on ordinary negligence instead.
How long do I have to file a dog bite lawsuit in California?
Two years from the date of the bite under Code of Civil Procedure section 335.1. A minor has until their twentieth birthday. If the dog belonged to a city, county, or other public agency, you must present a written government claim within six months under Government Code section 911.2, and after a written rejection you have only six months to file suit.
Does a dog bite have to break the skin?
Not for a civil claim. Johnson v. McMahan held that section 3342 applies where a dog seizes a person with its teeth even if the skin is never broken. The broken-skin definition in Penal Code section 398 applies only to that criminal information-disclosure provision.
What if the dog knocked me down but never bit me?
Section 3342 does not apply, but you can still recover. Under Drake v. Dean, a negligence claim requires no proof that the dog had dangerous propensities — only that the owner failed to exercise reasonable care. Common law strict liability is also available where the owner knew or should have known the dog was unusually dangerous.
Can I sue if I was partly at fault?
Yes. California is a pure comparative negligence state under Li v. Yellow Cab Co. Your recovery is reduced by your percentage of fault but is never barred, even if you are found mostly responsible.
Can I sue my landlord for a tenant’s dog?
Only if the landlord had actual knowledge of the dog’s dangerous propensities and had the power to remove it or end the tenancy. Under Uccello v. Laudenslayer, constructive knowledge is not enough, and a landlord has no duty to inspect for a tenant’s dangerous animal.
Are pit bulls banned in California?
No. Food and Agricultural Code section 31683 prohibits breed-specific regulation, apart from spay and neuter programs permitted under Health and Safety Code section 122331. Cities and counties may adopt stricter dangerous-dog rules, but not breed bans.
Who pays a dog bite claim?
Usually the owner’s homeowners or renters insurance. Policy limits and any breed exclusion frequently matter more to the outcome than the liability question does.
