A dog bite happens in a second. The questions afterward take longer: Who pays for the emergency room? Does it matter that the dog never bit anyone before? What if it happened at a friend’s house? California answers the biggest of those questions with a statute that is unusually direct. This guide walks through what the law says, where its limits are, and what to do in the first days after a bite. For an overview of how we handle these cases, see our dog bite lawyer page.

What does California’s dog bite statute say?

California Civil Code § 3342 makes the owner of a dog liable for damages suffered by anyone the dog bites while that person is in a public place or lawfully in a private place, including the owner’s own property. The statute applies “regardless of the former viciousness of the dog or the owner’s knowledge of such viciousness.”

That last phrase is the heart of it. Many states follow some version of a “one bite” rule, where the injured person has to show the owner knew the dog was dangerous. California’s statute does not require that showing for a bite. This is what lawyers mean when they call it strict liability.

What do you have to prove under § 3342?

The California civil jury instruction for the statute (CACI No. 463) breaks the claim into a few plain questions:

  • Was the defendant the dog’s owner?
  • Did the dog bite the injured person?
  • Was the person in a public place or lawfully on private property at the time?
  • Was the bite a substantial factor in causing harm?

Notice what is missing: no need to prove the dog had a history, and no need to prove the owner was careless with the leash or the gate. Those facts can still matter to the story, but they are not elements of the statutory claim.

What counts as “lawfully” on private property?

The statute defines it. A person is lawfully on the owner’s private property when performing a duty imposed by California law or by federal law or postal regulations (think mail carriers and utility workers doing their jobs), or when on the property by the owner’s invitation, express or implied.

Guests at a barbecue, a neighbor who was asked to feed the cat, and delivery workers usually fit comfortably within that language. Trespassers generally do not, which is one of the main limits on the statute.

Are there exceptions?

Yes, and they are narrow. Subdivision (b) of § 3342 says the statute does not authorize a suit against a governmental agency using a dog in military or police work when the bite happened while the dog was defending itself from an annoying, harassing, or provoking act, or assisting an agency employee in apprehending or holding a suspect (where there is reasonable suspicion of criminal involvement), investigating a crime, executing a warrant, or defending a peace officer or another person.

Two important limits on that exception are written into the statute itself:

  • It does not apply when the person bitten was not a party to, participant in, or suspected participant in the conduct that prompted the use of the dog. A bystander bitten by a police dog is outside the exception.
  • It applies only if the agency has adopted a written policy on the necessary and appropriate use of dogs for that work.

Claims involving a public agency also raise separate government-claim deadlines, which can be much shorter than the ordinary two-year period. If a public entity is involved, get advice quickly.

Does the statute cover injuries that are not bites?

Section 3342 is written about bites. When a dog knocks someone down, causes a cyclist to crash, or injures someone without biting, the claim generally has to proceed on other theories, such as ordinary negligence or a claim based on the owner’s knowledge of a dangerous propensity. Those theories have different proof requirements. Landlords and property managers can sometimes be part of the picture too, which overlaps with premises liability principles.

What does the owner have to do after a bite?

California Civil Code § 3342.5 says the owner of a dog that has bitten a person has a duty to take reasonable steps to remove the danger to others. When a dog has bitten people on at least two separate occasions, the statute allows an action to determine whether conditions have changed enough to remove the danger, and the court can make orders to prevent another incident.

What should you do right after a dog bite?

Get medical care. Bites can carry infection risk even when they look minor, and hand and face wounds deserve prompt attention. Tell the provider exactly how the injury happened so it is recorded accurately.

Identify the dog and the owner. Get the owner’s name, address, and phone number. Ask whether the dog’s vaccinations are current and note what you are told. If the owner is not present, note where the dog came from and who was with it.

Report the bite. Local animal control agencies handle bite reports and quarantine questions. A report creates an official record and helps protect the next person.

Photograph everything. Take photos of the wounds on the day of the bite and as they heal. Photograph torn clothing, the location, any broken gate or fence, and the dog if it is safe to do so.

Find witnesses. Neighbors, other dog walkers, and people at the park often saw what happened. Get names and numbers before everyone goes home.

Keep records. Save medical bills, receipts, and notes about missed work. Scarring, nerve damage, and fear of dogs can affect someone for a long time, especially children, and those effects should be documented as they happen.

Be careful with insurance calls. Bite claims are often paid through the owner’s homeowner’s or renter’s insurance. An adjuster may call quickly and ask for a recorded statement. You are not required to give the owner’s insurer a recorded statement, and it is reasonable to talk with a lawyer first.

How long do you have to bring a claim?

For most personal injury claims in California, Code of Civil Procedure § 335.1 sets a two-year limitation period. Claims involving minors, public agencies, or unusual facts can follow different rules, so do not assume the two-year clock is the only one that applies.

What if the owner is a friend or family member?

This is common, and it is uncomfortable. Many people hesitate because they do not want to sue a neighbor. In practice, these claims are often handled with the owner’s insurer, which is what that coverage exists for. A conversation with a lawyer can help you understand the options before you decide anything.
