California Dog Bite Law: Is a Dog Owner Automatically Liable When Their Dog Bites Someone?

By the Law Office of Frederick S. Schwartz

It is estimated that there are 1,300–1,500 reported dog bites per year in the San Fernando Valley. This works out to roughly 25–29 reported dog bites every week, or about 3–4 per day. Dog bites can cause far more than a temporary injury. Victims may suffer puncture wounds, nerve or tendon damage, infections, permanent scarring and disfigurement, emotional trauma, and significant medical expenses. When a child is attacked, the physical and psychological consequences can be particularly serious.

One of the first questions a dog-bite victim may ask is:

“Is the dog owner automatically responsible if their dog bites me in California?”

In many cases, the answer is yes .

California has one of the strongest dog-bite liability statutes in the country. Unlike states that follow what is sometimes called the “one-bite rule,” California generally does not require an injured person to prove that the dog had previously bitten someone or that the owner knew the dog was dangerous.

The starting point is California Civil Code § 3342 .

California Civil Code § 3342 and Strict Liability for Dog Bites

California Civil Code § 3342(a) establishes the state's statutory rule governing liability for dog bites. In substance, the statute provides that the owner of a dog is liable for damages suffered by a person who is bitten by the dog while in a public place or lawfully in a private place, regardless of the dog's former viciousness or the owner's knowledge of that viciousness.

The statute also recognizes that a person may be lawfully on the dog owner's property when performing a duty imposed by law or when present because of the owner's express or implied invitation.

The importance of this law cannot be overstated.

In a typical negligence case, an injured person must prove that the defendant acted unreasonably or failed to exercise reasonable care. California's dog-bite statute can impose strict liability on the dog's owner without requiring the victim to prove that the owner was negligent or previously knew the dog might bite.

California's official civil jury instruction, CACI No. 463 , explains that dog owners can be held responsible for harm caused by a dog bite regardless of how carefully they guarded or restrained their dogs.

Does California Have a “One-Bite Rule”?

Generally, no—not for liability under Civil Code § 3342.

You may have heard someone say:

“Every dog gets one free bite.”

That is not an accurate statement of California's dog-bite statute.

Under § 3342, an injured person generally does not have to prove that:

The dog previously bit another person;
The dog had previously behaved aggressively;
The owner knew the dog was vicious;
Neighbors had complained about the dog;
The owner had previously been warned about the dog; or
The owner negligently restrained the dog.

The dog's lack of a prior bite history therefore does not necessarily protect its owner from liability.

This is one of the most important facts for California dog-bite victims to understand.

What Must a Dog-Bite Victim Prove?

Although California imposes strict liability in qualifying dog-bite cases, that does not mean compensation is literally “automatic.”

According to California's dog-bite jury instruction, a plaintiff pursuing a claim under § 3342 generally must establish four basic facts:

The defendant owned the dog ;
The dog bit the plaintiff while the plaintiff was in a public place or lawfully on private property;
The plaintiff was harmed ; and
The dog's bite was a substantial factor in causing that harm .

Each of these elements can become important when an insurance company investigates or disputes a claim.

What Does “Lawfully on Private Property” Mean?

The location of the attack can be important.

Civil Code § 3342 protects someone bitten while in a public place as well as someone who is lawfully on private property , including the dog owner's property.

A person may be lawfully on private property because he or she was invited onto the property, either expressly or impliedly. The statute also addresses persons who enter private property while performing duties imposed by law.

This may include many ordinary situations—a social guest visiting someone's home, a customer entering a business, or a person performing an authorized service on the property.

The precise facts surrounding why the injured person was on the property should nevertheless be investigated in any serious dog-bite claim.

What if the Owner Says, “My Dog Has Never Bitten Anyone Before”?

This is one of the most common defenses a victim may hear following an attack.

Under California Civil Code § 3342, however, a dog's prior history generally is not required to establish the owner's statutory liability.

An owner cannot necessarily avoid responsibility simply by saying:

“He has never done this before.”

The statute specifically makes prior viciousness and the owner's knowledge of such viciousness unnecessary to the basic statutory claim.

A prior history can still become important for other reasons and other potential legal theories, but it is generally unnecessary to establish liability under § 3342 itself.

What if the Dog Owner Claims the Victim Provoked the Dog?

Strict liability does not mean that the circumstances surrounding the incident are irrelevant.

Insurance companies may investigate whether the injured person intentionally provoked the dog, voluntarily encountered a known risk, was unlawfully on the property, or otherwise contributed to the circumstances surrounding the incident.

California's authorities recognize that defenses involving assumption of risk or comparative fault may arise depending upon the particular facts.

This makes evidence extremely important. Witness statements, photographs, surveillance video, animal-control reports, medical records, and statements made by the owner immediately following the attack can help establish what actually happened.

Does the Bite Have to Break the Skin?

Not necessarily.

California authority cited in the official CACI instruction recognizes that the skin does not have to be broken for Civil Code § 3342 to apply.

This can be significant when the force of a dog's bite causes crushing, bruising, nerve injury, or other trauma even though the teeth do not produce a traditional puncture wound.

The important issue is the actual injury and whether the dog's bite caused it.

What Compensation May Be Available After a California Dog Bite?

The value of a dog-bite claim depends upon the particular circumstances and injuries. There is no universal formula.

Depending upon the evidence and circumstances, recoverable damages may include:

Medical expenses. Emergency-room treatment, physician care, wound treatment, medications, diagnostic testing, plastic surgery, physical therapy, and other reasonable medical care may be part of the claim.

Future medical treatment. Serious bites may require scar revision, reconstructive or plastic surgery, additional orthopedic treatment, neurological treatment, or psychological care.

Lost earnings. A victim who cannot work because of the injuries may have a claim for past lost income and, in appropriate cases, future loss of earning capacity.

Physical pain and suffering. Dog attacks can cause substantial immediate pain as well as prolonged discomfort during recovery.

Emotional distress and psychological injury. A violent animal attack can be frightening and traumatic. Some victims develop anxiety, nightmares, fear of dogs, or other persistent emotional symptoms.

Scarring and disfigurement. Permanent scars—particularly scars involving the face, hands, arms, or legs—can substantially affect the value of a claim.

Dog Bites Involving Children

Dog attacks involving children deserve particular attention.

Children may be especially vulnerable because of their height and inability to protect themselves during an attack. Injuries to the face and head can produce permanent scarring that continues to affect the child as he or she grows.

The psychological effects can also last well beyond the healing of the physical wounds.

For these reasons, a claim involving a child should not be evaluated solely by looking at the initial emergency-room bill. Future medical treatment, plastic-surgery opinions, scar maturation, psychological effects, and the long-term impact of visible disfigurement may all require consideration.

Who Actually Pays a Dog-Bite Claim?

Although the dog's owner may be legally responsible, an important practical question is:

Where does the money come from?

Many dog-bite claims are presented under applicable homeowners or renters insurance , depending upon the policy and circumstances. Determining whether insurance exists, which policy applies, and whether an exclusion affects coverage can therefore be an important part of investigating the claim.

Victims should be cautious about assuming that an early settlement offer from an insurance company represents the full value of their injuries.

This is particularly important when the victim has permanent scarring, future medical needs, or injuries whose long-term consequences are not yet known.

What Should You Do After a Dog Bite?

Your health should come first. Seek appropriate medical attention, particularly when there are puncture wounds, significant bleeding, possible infection, nerve symptoms, facial injuries, or injuries involving a child.

When possible, preserve evidence concerning the incident. Identify the dog and its owner, obtain contact information for witnesses, photograph the injuries throughout the healing process, preserve damaged or bloodied clothing, determine whether surveillance video exists, and retain medical bills and records.

It may also be appropriate to report the incident to the responsible local animal-control agency.

Be particularly careful about giving detailed recorded statements or signing releases presented by an insurance company before the nature and extent of the injuries are known.

How Much Is a California Dog-Bite Case Worth?

There is no legitimate way to place a value on a dog-bite case without considering the individual facts.

Two people can experience similar attacks and have dramatically different damages.

Factors that may affect value include the nature of the injury, medical expenses, future treatment, lost earnings, permanent scars, location and visibility of scars, plastic-surgery recommendations, nerve or tendon damage, psychological consequences, the victim's age, available insurance coverage, and the strength of the evidence establishing liability and damages.

A photograph taken immediately after an attack may demonstrate the severity of the original injury. Photographs taken weeks and months later can document whether scars have faded—or become permanent.

For that reason, careful documentation can be critical.

California Law Provides Important Protection to Dog-Bite Victims

The central point of California Civil Code § 3342 is straightforward:

A dog owner generally cannot escape liability for a bite simply by claiming that the dog had never bitten anyone before or that the owner did not know the dog was dangerous.

California's official jury instructions reflect this principle. A dog owner may be responsible for the harm caused by a dog bite regardless of how carefully the dog was guarded or restrained, provided the statutory requirements are established.

Every case, however, depends on its particular facts. Questions involving ownership, lawful presence, causation, comparative fault, assumption of risk, insurance coverage, damages, and the circumstances surrounding the attack should be carefully investigated.

Injured in a Dog Bite or Dog Attack in California?

If you or a family member has been seriously injured by a dog, the Law Office of Frederick S. Schwartz (located in Encino) can evaluate the circumstances of the incident, applicable California law, available insurance coverage, medical evidence, and the full extent of the damages.

An evaluation can also help determine whether Civil Code § 3342 or other theories of liability may apply and what evidence should be preserved before it disappears.
