What California Civil Code Section 3342 Requires You to Prove

Section 3342 is a strict liability statute, which means liability attaches without any proof of fault. Three things have to be true:

• A dog bit you. Not scratched, not knocked over. Bit.
• You were in a public place, or you were lawfully in a private place. The statute counts you as lawfully present on private property if you were there by invitation, express or implied, or performing a duty imposed by state or federal law or by the postal service.
• The bite caused you damages.

Nothing on that list involves the dog’s history. A dog with a spotless record and a certificate from obedience school produces the same liability as a dog with three prior attacks. The owner’s knowledge does not matter either. Neither does a “Beware of Dog” sign, which changes nothing about the owner’s legal responsibility to a lawful visitor.

The statute reaches the owner’s own property. A guest bitten in a friend’s living room has the same claim as someone bitten on a sidewalk.

Why California Is Not a One Bite State

The “one bite rule” is the older common-law idea that an owner is only responsible once the dog has shown a dangerous streak. California replaced that rule for bite cases when it enacted section 3342. Prior conduct is no longer the gate.

The common law still matters in one important way. Section 3342 covers bites and nothing else. A dog that lunges, knocks an elderly person off a curb, and breaks her hip has not bitten anyone, so the statute does not apply. Those claims proceed under ordinary negligence, where the question is whether the owner used reasonable care given what they knew about the animal. The California Court of Appeal made that path explicit in Drake v. Dean (1993) 15 Cal.App.4th 915, a case involving a tethered dog that jumped on a woman in a driveway.

California’s hospital data draws the same line. The state’s emergency rooms recorded 2,910 visits in 2024 under the injury code for “struck by dog” (ICD-10-CM W54.1XXA), which is a separate code from the one used for a dog bite. Knock-downs and collisions get counted on their own. Those are the injuries section 3342 does not reach, and they run on negligence instead.

Chase injuries, trip-and-fall injuries, and dog-caused bicycle and motorcycle crashes all live in that negligence category. They are still real claims. They are just proved differently.

The Exceptions to Strict Liability

Trespassing

A trespasser cannot use section 3342. The word “lawfully” in the statute is doing that work. Someone who climbs a fence into a backyard was not lawfully in a private place, so the strict liability rule is unavailable to them. Insurance adjusters stretch this argument regularly, and it often fails. A delivery driver, a meter reader, a mail carrier, and a child who walked through an open gate on a path neighbors had used for years are usually all lawfully present.

Provocation

Provocation is not written into section 3342 for private dog owners. It comes from case law and from the general defenses available in any injury case. Insurers raise it constantly. Teasing, hitting, or cornering a dog can reduce or eliminate recovery. Standing near a dog, walking past it, or reaching down to pet a dog whose owner said it was friendly is not provocation, though an adjuster may open by calling it that.

Veterinarians and Professional Handlers

People who handle dogs for a living generally accept the risk of being bitten as part of the job. California courts applied that reasoning to a veterinary assistant bitten while restraining a dog for treatment in Nelson v. Hall (1985) 165 Cal.App.3d 709, and the California Supreme Court extended it to a kennel worker in Priebe v. Nelson (2006) 39 Cal.4th 1112. The rule is narrower than insurers claim. It applies to someone who took custody of the dog in a professional capacity, not to every person who happens to work around animals.

Police and Military Dogs

Section 3342 subdivisions (b) through (d) shield a government agency when its dog bites while defending itself from a provoking act, apprehending a suspect, investigating a crime, executing a warrant, or defending an officer. Two limits sit inside that shield, and both are easy to miss. Under subdivision (c), the exception does not apply at all if the person bitten was not involved in, and not suspected of being involved in, whatever prompted the use of the dog. A bystander bitten during an arrest is not covered by the exception. Under subdivision (d), the agency only gets the protection if it has adopted a written policy on the necessary and appropriate use of a dog for those purposes. No written policy, no exception.

Who Can Be Liable Besides the Owner

Section 3342 names the owner. An owner with no assets and no insurance is not always the end of the case, because other parties can be liable under negligence principles:

• Landlords. A landlord who has actual knowledge that a tenant’s dog is dangerous, and who could have prevented the harm by exercising ordinary care, can be liable. That framework comes from Uccello v. Laudenslayer (1975) 44 Cal.App.3d 504 and was refined in Donchin v. Guerrero (1995) 34 Cal.App.4th 1832. Actual knowledge can be proved with indirect evidence, such as prior complaints or testimony from delivery workers.
• Anyone who was caring for the dog. A dog sitter, a boarding facility, a relative caring for the dog, or a business that lets a dog roam its premises can be liable in negligence even though they do not own the animal.
• Property owners and managers. Broken fencing, a propped gate, or an ignored history of loose dogs on a property can support a claim against whoever controlled that property.

How Your Own Conduct Affects Recovery

California uses pure comparative fault. If a jury decides you were partly responsible, your award is reduced by your percentage of fault rather than eliminated. A person found 20 percent at fault on a $100,000 verdict recovers $80,000. Even a plaintiff assigned a majority of the fault still recovers something.

Insurers press hard on what you were doing in the seconds before the bite. They do not need a complete defense. A reduction is worth money on its own.

You Have Two Years to File

California’s two-year filing deadline applies to dog bite claims. Code of Civil Procedure section 335.1 gives you two years from the date of the injury to file suit. Miss it and the claim is gone. The strength of the facts will not save it.

Two situations change the math. When the injured person is a child, section 352(a) pauses the clock during the years of minority, so a bitten child generally has until two years after turning 18. When a public entity is involved, such as a city animal control agency or a police department, a written government claim is normally due within six months under Government Code section 911.2, long before the two-year deadline. Those two rules do not combine. Code of Civil Procedure section 352(b) says the minor’s tolling does not apply where a government claim is required, so a child bitten by a police K-9 or on public property is still inside the six-month window. Deadlines turn on facts specific to your case. Confirm yours with an attorney rather than relying on a general rule.

What a Dog Bite Claim Can Recover

Recoverable damages fall into two groups. Economic damages have receipts attached: emergency treatment, reconstructive surgery, follow-up care, psychological therapy, lost wages, reduced future earnings, and funeral costs in a fatal attack. Non-economic damages cover pain and suffering, disfigurement, loss of use of a body part, loss of consortium, and the anxiety many people carry around dogs afterward.

Scarring and disfigurement are their own category of harm. The wound closes. The injury does not end there. Scar revision surgery is often staged over years, laser treatment runs in series, and a visible scar on the face, neck, or hands carries a daily social cost that a healed forearm does not. The American Society of Plastic Surgeons reported that surgeons repaired 26,906 dog bite injuries in 2018, down 4 percent from 27,923 in 2017. Many minor bites are never counted.

Children get bitten in the face. A small child’s face is at a large dog’s head height, so bites to children concentrate on the cheeks, lips, nose, and scalp. Facial reconstruction on a growing child frequently has to be repeated as the face develops, which means the full cost is not knowable in the first year. Settling a child’s claim early, before a pediatric plastic surgeon has projected that future care, is one of the more expensive mistakes a family can make.

Homeowners’ and Renters’ Insurance Usually Pays

Most dog bite settlements in California are paid by a homeowners’ or renters’ insurance policy. The owner rarely pays personally. The liability section of a standard policy covers bites, often including bites that happen away from the insured property.

California produces more dog bite claims than any other state. The Insurance Information Institute and State Farm put the 2024 California count at an estimated 2,417 claims, averaging $86,229 each and $208.4 million in total value. The 2023 average was $68,125. Their tally includes other dog-related injuries such as fractures and blunt-force trauma, so it is not bites alone.

Two things are worth checking early. Some policies exclude specific breeds or exclude any dog with a prior bite, and some cap animal liability at a figure well below the medical cost of a serious facial injury. Where an owner’s coverage falls short, a landlord’s policy, a business policy, or your own underinsured coverage may come into play. People also hesitate to make a claim because a neighbor or friend owns the dog. The claim is against an insurance policy that exists for exactly this situation.

Infection Risk and Why Prompt Treatment Matters

Infection was diagnosed at 3.0 percent of California dog bite emergency room visits. The California Department of Public Health published that figure in 2023, after reviewing 523,689 dog bite emergency room visits from 2005 through 2019 and finding infections of skin, tissue, joints or bone at 15,494 of them. Older patients fared worse. The rate ran from 1.0 percent in patients aged 10 to 14 to 7.7 percent in patients aged 85 and older. Those numbers count infection visible at the visit itself, not infection that showed up afterward.

Staphylococcus is the organism found most often. In the same California study, bacteria were identified in 106 dog bite wound infections, and Staphylococcus species led at 60 of them (56.6 percent), ahead of Pasteurella species at 28 (26.4 percent). About half of the staph isolates were resistant to methicillin-type antibiotics. The range of bacteria involved is wide. A 2012 reference study obtained sequences for 353 bacterial taxa in the canine oral cavity, 80 percent of them still unnamed, and found only 16.4 percent of them shared with humans.

Punctures are the dangerous ones. They seal over at the surface while carrying bacteria deep into tissue. Tetanus, MRSA, and capnocytophaga are all documented risks. Anyone with a weakened immune system should be seen the same day.

Prompt treatment protects the claim as well as the wound. The medical record created that day is what ties the injury to the dog, times it, and documents its severity. Gaps get used against you. A defense adjuster will point to several days between the bite and the first visit.

The California data speaks to that argument. Four percent of dog bite patients returned to an emergency room a median of three days after their first visit. Of the 3,794 infections found at those return visits, 3,199 had not been documented at the first one. That is 84.3 percent.

What to Do After a Dog Bite in California

• Get medical care the same day, at an emergency room for any deep, bleeding, or facial wound.
• Photograph the wound before it is bandaged, then again as it heals over the following weeks.
• Get the owner’s name, address, and insurance information, plus proof of the dog’s rabies vaccination.
• Report the bite to your local animal control agency. Reporting requirements, quarantine periods, and leash rules are set by your city or county, so they differ across California.
• Collect names and phone numbers for anyone who saw it happen.
• Do not give a recorded statement to the owner’s insurer before speaking with a lawyer.

Reporting matters beyond your own case. California’s dangerous dog law at Food and Agricultural Code section 31601 and following declares that these animals require statewide regulation, and the process for declaring a dog potentially dangerous or vicious generally begins with a report to a local agency.
