To report a dog bite in California, contact your local animal control agency or county health department as soon as you can after the incident. The agency will open an investigation and place the dog under a mandatory 10-day observation period to rule out rabies. Separately, California’s strict liability law makes the owner financially responsible for your injuries, and you have two years from the date of the bite to file a lawsuit.
Who Must Report and Where the Report Goes
California doesn’t leave reporting up to the victim alone. The person who was bitten, the dog’s owner, and any physician or veterinarian who treats the wound all have a legal duty to notify the local health officer.1California Department of Public Health. Investigation, Management, and Prevention of Animal Bites in California In practice that means calling your county animal control office or health department. Some counties take reports online, others require a phone call or an in-person visit. Check your county’s site for the intake method it prefers.
The legal foundation is rabies control. California’s Health and Safety Code lets the state director designate counties or regions as rabies areas when the virus poses a public health hazard, and reporting each bite is how officials figure out whether anyone was exposed.2California Legislative Information. California Health and Safety Code Division 105, Part 6, Chapter 1
What to Have Ready When You Report
The more the investigating officer knows, the faster the case moves. Try to give them:
- The date, time, and specific location of the bite.
- A description of the dog: breed, color, size, and any tags, collar, or visible microchip number.
- The owner’s name, address, and phone number if you have them.
- A description of your injuries and any medical care you received.
If the dog was a stray or the owner left the scene, report what you saw. Animal control can scan a recovered dog for a microchip and trace the owner through registry databases. Take photos of your injuries and the location if you can. Those images become part of the official record and support any later insurance claim or lawsuit.
What Happens to the Dog: The 10-Day Quarantine
Once the bite is reported, the local agency places the dog under a 10-day observation period.3OC Animal Care. Report an Animal Bite The reasoning is simple: a dog still healthy after ten days wasn’t shedding rabies virus at the time of the bite. An officer examines the animal at the start of the period and again at the end.
Quarantine can be served two ways. If the dog is current on its rabies vaccination and the owner can keep it strictly confined on private property, the agency may allow the observation to happen at home. State law defines that confinement as isolation by leash, closed cage, or fenced enclosure, with no contact with other animals or with people outside the household, and the dog must be available whenever the officer wants to examine it.4California State Parks. California Health and Safety Code – Rabies Laws and Regulations
When the vaccination is out of date, the bite was severe, or the owner can’t safely confine the dog, the animal is impounded at a shelter or approved veterinary facility instead.3OC Animal Care. Report an Animal Bite The owner usually pays the boarding costs.
One boundary worth naming: dogs used by state, county, or city law enforcement agencies are exempt from the quarantine requirement when the bite happened on duty. The agency still has to make the dog available for examination and notify the local health officer if it later shows abnormal behavior.4California State Parks. California Health and Safety Code – Rabies Laws and Regulations
If the Owner Hides the Dog or Breaks Quarantine
California treats interference with the process as a crime. Anyone who deliberately conceals information about the location or ownership of a biting dog to prevent quarantine is guilty of a misdemeanor.5California Legislative Information. California Health and Safety Code 121705
Violating the quarantine order itself is a separate misdemeanor. It carries up to one year in county jail, a fine of $100 to $1,000 for each day the violation continues, or both.4California State Parks. California Health and Safety Code – Rabies Laws and Regulations The per-day structure means the exposure climbs quickly. The same penalties apply to an owner who refuses to produce the dog after being ordered to do so. This matters to you as the bite victim, because an uncooperative owner forces public health officials to treat the bite as a possible rabies exposure, which can mean thousands of dollars in post-exposure treatment.
Your Right to Compensation from the Owner
California Civil Code Section 3342 holds the owner liable for your injuries whether or not the dog ever bit anyone before. You don’t have to prove the owner was careless or knew the animal was dangerous. If the dog bit you in a public place, or on private property where you had a right to be, the owner owes damages.6California Legislative Information. California Code CIV 3342
Being “lawfully on private property” covers anyone there by invitation, express or implied, and anyone performing a duty required by law, such as a mail carrier or a utility worker.6California Legislative Information. California Code CIV 3342 Guests, delivery drivers, and contractors qualify. Trespassers do not.
Many dog owners carry homeowners’ or renters’ insurance with personal liability coverage, and bite claims are usually filed against that policy. If the owner has no insurance, they are personally responsible for whatever a court awards.
Defenses the Owner Might Raise
Strict liability isn’t absolute. California recognizes several defenses that can limit or defeat a bite claim:
- Trespassing. If you were on the owner’s property without permission or legal authority, Section 3342 doesn’t apply.7Justia. CACI No. 463 – Dog Bite Statute (Civ. Code, 3342) – Essential Factual Elements
- Provocation. An owner who can show you provoked the dog may argue your own conduct contributed to the injury, which can reduce your recovery under California’s comparative fault rules.
- Assumption of risk. Veterinarians, kennel workers, and others whose jobs involve handling dogs are generally treated as having accepted the occupational risk of being bitten, and courts have consistently blocked strict liability claims from professionals in those roles.7Justia. CACI No. 463 – Dog Bite Statute (Civ. Code, 3342) – Essential Factual Elements
- Police and military dogs. A government agency isn’t liable under Section 3342 when the dog bit while defending itself from provocation, apprehending a suspect, investigating a crime, executing a warrant, or defending an officer. The defense applies only when the victim was involved in the activity that prompted the dog’s use, and the agency must have a written use-of-force policy for the dog.6California Legislative Information. California Code CIV 3342
Even where strict liability is blocked, a general negligence claim may still be available. That’s a harder case because it requires proof the owner failed to use reasonable care, but courts leave the door open.
Dangerous and Vicious Dog Designations
Separate from your civil claim, the investigation can produce an official designation that restricts how the owner keeps the dog going forward. An animal control officer who finds probable cause can petition the local superior court or use a county administrative hearing process to make the designation formal.
A dog is “potentially dangerous” under any of three criteria:
- It bit someone without provocation and caused an injury less severe than the statutory definition of “severe.”
- Without provocation, it forced someone to take defensive action to avoid injury on two separate occasions within 36 months while off the owner’s property.
- Without provocation, it killed or seriously injured a domestic animal on two separate occasions within 36 months while off the owner’s property.8California Legislative Information. California Food and Agricultural Code 31602
An owner of a potentially dangerous dog must keep it in a secure fenced yard that children can’t enter and the dog can’t escape. Off the property, the dog must be on a substantial leash under the control of a responsible adult.9California Legislative Information. California Code FAC 31642
The “vicious” label applies in two situations: the dog unprovokedly inflicted a severe injury or killed a person, or the dog was already designated potentially dangerous and either continued the aggressive behavior or was kept in violation of the restrictions.10California Legislative Information. California Code FAC 31603 Requirements are heavier, including a specially designed escape-proof enclosure, and in the most serious cases the court can order the dog euthanized. Violating the conditions carries fines of up to $500 for a potentially dangerous dog and up to $1,000 for a vicious dog.
The Two-Year Deadline to Sue
You have two years from the date of the bite to file a personal injury lawsuit. That comes from Code of Civil Procedure Section 335.1, which covers claims for injury caused by another person’s wrongful act or neglect.11California Legislative Information. California Code CCP 335.1 Miss it and the court will almost certainly throw the case out, no matter how strong your facts are.
Two years feels like a lot until you spend a few months on treatment, another few on insurance negotiations, and more on chasing records. If a child was bitten, the clock is generally extended because minors have until two years after turning 18 to file. Either way, start early. Evidence disappears and witnesses forget.
What Your Damages Can Cover
A successful claim can include both economic and non-economic damages. Economic damages compensate you for real financial losses: emergency treatment, surgery, physical therapy, follow-up care, prescriptions, lost wages, and reduced future earning capacity if the injury is permanent. Bite hospitalizations run high. Non-economic damages cover harm without a receipt, including pain, emotional distress, scarring, disfigurement, and reduced quality of life.
Where the owner’s conduct was especially reckless, such as repeatedly letting a known-aggressive dog roam, a court can add punitive damages to punish the behavior rather than compensate you.
