Dog bite claims

California treats dog bites differently from most injury claims. For a bite, the owner is liable whether or not the dog had ever shown aggression and whether or not the owner did anything wrong. That makes the liability question simpler than usual and shifts the case onto the injury, the coverage, and the details that fall outside the statute.

This is general information, not legal advice, and it does not tell you whether you have a case.

The strict-liability statute

Civil Code § 3342 makes a dog owner liable for the damages a bite causes when the person bitten was in a public place or lawfully in a private place, including the owner's own property. The statute applies regardless of the dog's prior behavior and regardless of the owner's knowledge or care. There is no "one free bite" for the statutory claim.

The main limits on § 3342:

• It covers bites. Other injuries a dog causes — knocking someone down, causing a bicycle or motorcycle crash, a fall while backing away — are outside the statute and go through negligence.
• The person has to be lawfully present. A trespasser generally cannot use § 3342, though a negligence claim may still exist.
• Assumption of the risk. A veterinarian, groomer, or professional dog handler who is bitten in the course of the work they were hired to do may be found to have assumed that risk.

The negligence route

When § 3342 does not fit — a non-bite injury, a trespasser, an injury caused by someone else's failure to restrain a dog — the claim is ordinary negligence. That can mean:

• Scienter, or knowledge: the owner knew or should have known the dog had a dangerous propensity and failed to guard against it. Prior bites, aggressive lunging, warning signs, a muzzle, or breed- specific restrictions in a lease can all show knowledge.
• Negligent control: an unleashed dog where leashing was required, a gate left open, a chain that was too long, a known escape route.
• Negligence per se: violation of a local leash law or animal-control ordinance that caused the injury.

Comparative fault in dog bite cases

The defense in a bite case usually argues the person brought it on themselves: they teased or hit the dog, reached into a yard or a car, ignored a "beware of dog" sign, or startled a sleeping animal. California uses pure comparative fault, so provocation reduces a recovery by the injured person's share rather than defeating the claim, and deliberate provocation is weighed differently from an innocent movement a dog reacted to. With a young child, the provocation argument carries little weight, because a child that age is generally held to little or no standard of care.

Who pays

A dog bite claim is almost always paid by the owner's homeowner or renter insurance, which typically includes personal liability coverage for injuries the household causes, including by a pet. Some policies exclude certain breeds or a dog with a bite history, and some renters have no coverage at all. Identifying the policy early — and whether the bite happened at a home the owner owns, rents, or was visiting — is a first step. When the owner has no coverage, the claim may depend on the owner's own assets or on another responsible party.

More than one person can be responsible. A dog walker, a pet sitter, a boarding facility, or a friend watching the dog can be a "keeper" of the dog for negligence purposes and may carry their own coverage or a business policy. At a dog park or on a walk, the owner is still the owner for § 3342. Sorting out who had the dog, under what arrangement, and with what insurance is part of the early work.

Landlord liability

A landlord is generally not responsible for a tenant's dog just for being the landlord. The exception is narrow: a landlord can be liable when the landlord had actual knowledge that a specific tenant's dog was dangerous and had the ability to do something about it — for example, by enforcing a lease term or refusing to renew — and did not. Proving the landlord's actual knowledge, usually through prior complaints, incident reports, or the landlord's own communications, is the whole ballgame in these cases.

Children and facial injuries

Children are bitten more often than adults, are bitten on the face and head far more often because of their height, and are more likely to be left with permanent scarring and the psychological effects that follow a dog attack. A young child is generally held to little or no standard of care, which limits the comparative-fault argument. These claims often need input from plastic surgery on future revision procedures and from mental-health providers on the lasting effects, and a claim on a minor's behalf has its own procedural rules, including court approval of any settlement.

Delivery and postal workers

Mail carriers, package couriers, meter readers, and food-delivery drivers are bitten routinely, usually while lawfully on the property to do their job, which places the claim squarely within § 3342. A worker injured on the job also has a workers' compensation claim against their employer; the § 3342 claim against the dog owner is a separate, third-party claim, and the two are coordinated, with the workers' compensation carrier usually holding a lien against the third-party recovery.

Reporting and quarantine

A dog bite in California should be reported to the local animal-control or public-health agency. Reporting triggers a rabies-observation period during which the dog is confined and watched, usually for ten days, either at home or at a shelter depending on the dog's vaccination status and history. The report also creates an official record of the bite, the dog, and the owner that is useful to the claim. Reporting is separate from, and does not replace, the injury claim.

Some counties run a "potentially dangerous" or "dangerous dog" designation process, which can impose conditions on how the dog is kept — secure enclosure, muzzling in public, mandatory insurance — or, in serious repeat cases, order the dog removed. A finding in that process, and any prior designations for the same dog, are part of the record for a negligence claim and for showing the owner's knowledge.

Making a claim does not mean the dog is euthanized

People sometimes hesitate to report a bite or bring a claim because they do not want the dog put down, especially when the owner is a friend, a neighbor, or a family member. Those outcomes run on different tracks. What happens to the dog is decided by animal control and, where applicable, the dangerous-dog process, based on the circumstances of the bite and the dog's history. The injury claim is a separate matter that is paid by insurance. Bringing a claim is not the same as asking for the dog to be destroyed.

What is different about working a dog bite case

A dog bite claim runs on the same track as any injury claim (the claims process), but the path is shorter than most because the liability question is usually settled by the statute. After treatment and the animal-control report, the work is: identify the owner and the policy, gather the medical records and the photographs of the healing wounds, document any prior history of the dog, and — where the injury is lasting — get opinions on future scar-revision surgery and on psychological treatment. A claim for a child requires a court to approve any settlement, which adds a step and some time.

Injuries in a dog attack

Dog bites cause puncture wounds and lacerations that carry a high infection risk, crush injuries and nerve damage from the jaw pressure, tendon and ligament damage to hands and arms raised in defense, scarring, and, for children especially, lasting psychological injury. Because scarring and trauma responses are long-term, documenting future care — revision surgery, therapy — matters as much as the initial treatment record. The injury pages cover how each is documented and disputed.

Deadlines

For the injury claim, the deadline to file suit is generally two years from the bite. A claim on behalf of an injured child follows different timing rules. If the dog is owned by a government agency — a police or military dog, for example — a written government claim is due within six months. Reporting to animal control should happen immediately, regardless of the claim deadline.

What to do after a dog bite

• Get medical care — bites need cleaning, and infection can set in fast.
• Report the bite to local animal control or public health.
• Get the owner's name, address, and insurance information.
• Identify the dog, its vaccination status, and where it is kept.
• Photograph the injuries over time as they heal, and the location.
• Get names and numbers for any witnesses.
• Ask about prior incidents involving the same dog.
• Do not give a recorded statement to the owner's insurer before advice.

Common questions

Is California a "strict liability" state for dog bites?

Yes, for bites. Under Civil Code § 3342, a dog owner is liable for a bite that injures a person in a public place or lawfully on private property, whether or not the dog had ever bitten before and whether or not the owner knew it might. The "one free bite" idea does not apply to the bite statute.

What if the dog knocked me down but did not bite me?

The strict-liability statute covers bites specifically. A knock-down, a scratch, or a fall while fleeing is handled as an ordinary negligence claim, which usually requires showing the owner knew or should have known the dog was dangerous or failed to control it reasonably.

Who actually pays a dog bite claim?

Usually the dog owner's homeowner or renter insurance. That is why the claim is against the owner, not really against them personally — the policy is what responds. If the owner has no such policy, options narrow.

How long do I have to file a dog bite claim in California?

Generally two years from the bite for the injury claim (Code Civ. Proc., § 335.1). A claim for an injured child follows different timing rules. Reporting to animal control should happen right away, separate from the claim.
