Are you liable if your dog bites someone in California?
Yes. In California, you are absolutely liable for any injury caused by your dog, and it does not matter whether you knew the dog was vicious or had ever shown aggression before. People often ask us whether prior knowledge changes anything, and in California there is no exception built around it. There is one caveat, which applies when the person bitten was trespassing on your property.
That single rule surprises a lot of dog owners, and it surprises a lot of bite victims too. Below, we break down what strict liability actually means in practice, why hiring a dog walker does not shift responsibility off your shoulders, and what an injured person should understand about their claim.
What does “strict liability” mean for a dog bite in California?
Strict liability means the owner’s knowledge and intentions are not the issue. In many injury cases, the person bringing the claim has to show that someone behaved carelessly. With a dog bite in California, the analysis is far simpler: if your dog bit someone and caused injury, you are responsible for that injury.
This is why the common defenses dog owners reach for tend not to work. “He has never done that before.” “She was fine with everyone until now.” “There was no reason to think he would bite.” Those statements may be entirely true, and they still do not remove liability. A first-time bite from a dog with a spotless history is treated the same as a bite from a dog with a documented problem.
For an injured person, that matters enormously. You do not have to reconstruct a history of aggression or prove the owner ignored warning signs in order to have a claim.
Does the trespasser exception protect a dog owner?
The one caveat to liability is a trespasser on your property. If someone is on your property unlawfully when the bite happens, the analysis changes.
That exception is narrower than most people assume. A guest you invited, a neighbor who came to the door, a child who was welcome in your yard, a delivery worker, or anyone else lawfully present is not a trespasser. Being on private property is not the same thing as trespassing, and owners who assume the exception covers any bite that happens at home are often mistaken.
Because “lawfully present” versus “trespassing” can turn on specific facts about how and why the person was there, this is exactly the kind of question worth putting to an attorney rather than guessing at.
If a dog walker was holding the leash, who is responsible?
The owner. Even if your dog walker is walking your dog and the dog bites someone, you are ultimately responsible.
Handing the leash to someone else does not hand off liability with it. The same logic follows the dog wherever it goes with a hired handler, a friend, or a family member. If you own the dog, you own the consequences of what the dog does.
This is a point we emphasize with dog owners in Los Angeles, because it is so commonly misunderstood. People assume that paying a professional to walk the dog transfers the risk to that professional. It does not. The practical takeaway is straightforward: be careful out there, and always make sure you have control over your dog, including when someone else is holding the leash on your behalf.
Why does dog bite liability matter so much for injury victims?
Dog bite injuries are not minor by default. Puncture wounds, torn tissue, nerve damage, infection risk, scarring, and the lasting fear that follows an attack are all real consequences, and children are especially vulnerable because of where on the body a bite tends to land.
Because California treats owner liability so clearly, the fight in these cases usually moves to a different question: what is the injury actually worth. That is where insurers get involved, and where the numbers they offer early often bear little relationship to the full cost of medical treatment, follow-up care, time away from work, and permanent scarring.

Frequently asked questions about dog bite liability in California
Do I have to prove the dog had bitten someone before?
No. In California, a dog owner is absolutely liable for any injury caused by their dog, regardless of whether the owner knew the dog was vicious. As LA Injury Attorneys explains to clients, you do not need to establish a history of prior bites or aggression. A first-time bite is treated the same as a bite from a dog with a known problem, subject to the trespasser caveat.
Is the dog owner still responsible if a dog walker was in charge?
Yes. Even if a dog walker is walking the dog when the bite happens, the owner is ultimately responsible for the injury. Hiring a professional handler does not transfer liability away from the owner. LA Injury Attorneys raises this frequently with Los Angeles dog owners, because many assume paying someone else to walk the dog shifts the legal risk along with the leash.
Does the trespasser exception apply to anyone on private property?
No. The caveat applies to a trespasser, meaning someone on the property unlawfully. Invited guests, neighbors, delivery workers, and others lawfully present are not trespassers simply because the bite happened on the owner’s property. Whether someone counts as a trespasser depends on the specific facts, which is why LA Injury Attorneys reviews these details during a free consultation.
