Under California dog bite law, owners are strictly liable when their dog bites someone in a public place or while the victim is lawfully on private property. This applies regardless of the dog’s bite history. Victims do not need to prove the owner was negligent or knew the dog was dangerous. Liability attaches automatically under Civil Code 3342.
California is one of the strictest states in the country on this issue. California personal injury lawyers and Glendale personal injury lawyers handle these claims under the same rules statewide.
Yes. California applies strict liability under Civil Code Section 3342, meaning a dog owner is automatically responsible when their dog bites someone, even without any prior aggressive behavior, and even if the owner took precautions.
Two conditions must be met: the bite occurred in a public place, or the victim was lawfully on private property at the time.
California law defines “lawfully present” broadly. People covered include:
The bite does not need to break skin to qualify. In Johnson v. McMahan (1998), a court upheld a claim after a dog closed its jaws on a roofer’s pants rather than his leg, causing him to fall from a ladder.
Non-bite injuries, such as being knocked over or scratched, are not covered under Section 3342. Those claims fall under proving negligence in a personal injury case, where the victim must show the owner failed to exercise reasonable care.
A personal injury lawyer can evaluate whether your bite qualifies under the statute. California liability laws apply a similar strict liability framework to other injury contexts.

No. California does not follow the one-bite rule. The one-bite rule, used in some other states, means an owner is only liable after they knew their dog had a history of aggression. The first bite essentially goes unpunished under that framework.
California eliminated that standard when it enacted Civil Code Section 3342. A first bite creates full liability for the owner, with no exception for dogs with no prior history.
Saying “my dog has never bitten anyone before” is not a defense in California. The statute makes the history of the dog irrelevant. Liability exists from the moment the first bite occurs.
California strict liability has three recognized exceptions: trespassing, provocation, and police or military dog exemptions. A fourth defense, assumption of risk, applies in limited occupational contexts.
After a bite in California, the dog must be quarantined for 10 days, and animal control will investigate. Repeated biting can lead to a “potentially dangerous” or “vicious” designation and, in severe cases, euthanasia.
The 10-day quarantine is mandatory. If the dog is current on vaccinations, it can typically be quarantined at home under the owner’s supervision. Unvaccinated dogs are held at a shelter or veterinary facility. The quarantine period monitors for signs of rabies, not as punishment for the bite itself.
Animal control will review the vaccination records, the dog’s bite history, whether the dog was at-large, and whether the victim may have provoked the attack. This assessment determines what designation, if any, follows.
Potentially dangerous (Food and Agricultural Code Section 31602): triggered by an unprovoked bite causing a non-severe injury, or two unprovoked aggressive incidents within 36 months. Restrictions include a secure enclosure, leash requirements outside the property, and up-to-date vaccinations.
Vicious (Food and Agricultural Code Section 31603): triggered by an unprovoked bite causing severe injury or death, or when a previously designated “potentially dangerous” dog repeats the behavior after the owner has been notified. A vicious designation can result in the dog being removed from the area or euthanized.
Owners receive written notice and have the right to a hearing before any permanent designation or euthanasia order takes effect. No dog can be euthanized without this due process.

All animal bites to humans must be reported to local animal control or the local health officer under California state regulations. Mandatory reporting protects both the victim and the public from rabies exposure.
Under Penal Code Section 398, a dog owner has 48 hours after a bite to provide the victim with their name, address, phone number, and the dog’s license tag number, along with rabies vaccination status. Failure to do so is an infraction punishable by a fine of up to $100.

Dog bite victims in California can recover medical expenses, lost wages, pain and suffering, emotional distress, and future care costs, all covered under the owner’s strict liability.
Homeowners and renters insurance often covers dog bite lawsuit California claims, but some policies exclude specific breeds. If the owner has no insurance, they are personally liable for the full judgment.
Not every bite justifies a formal claim, but serious injuries, permanent scarring, and emotional trauma usually do. A dog bite attorney can assess the strength of your case and help you recover the full value of your damages.

Yes. California applies strict liability under Civil Code Section 3342, meaning the owner is responsible for a bite regardless of the dog’s history or the owner’s knowledge of aggression. Victims do not need to prove negligence or show that the owner did anything wrong to recover compensation.
No. California eliminated the one-bite rule when it enacted Civil Code Section 3342. A first bite creates full liability for the owner, and the dog’s prior good behavior is not a valid defense. The owner is liable from the moment the first bite occurs.
Animal control opens an investigation, initiates a mandatory 10-day quarantine of the dog, and contacts the owner to obtain vaccination records and contact information. The findings from this process determine whether the dog receives any formal dangerous or vicious designation.
You have two years from the date of the bite to file a personal injury lawsuit under California Code of Civil Procedure Section 335.1. If a government entity is involved, the deadline drops to six months to file an administrative claim first.
Yes, in certain cases. A dog designated as vicious under Food and Agricultural Code Section 31603, due to causing severe injury or repeating dangerous behavior after a prior designation, can be ordered removed from the area or euthanized after a formal hearing.
Trespassing is a recognized defense under Civil Code Section 3342, which only protects people who are lawfully present. If you were trespassing, strict liability may not apply to your claim, though courts may treat child trespassers differently depending on the circumstances.
Often yes. Homeowners and renters insurance policies frequently cover dog bite liability claims, making them a primary source of compensation for victims. However, some policies exclude specific dog breeds. If the owner has no insurance, they remain personally liable for the full damages.
