Is a dog owner strictly liable for a bite in California?

California · updated 2026-08-31 · 540 words · 5 authorities cited

In California, a dog owner is generally held strictly liable for damages when their dog bites someone in a public place or while the person is lawfully on private property 2. This liability applies regardless of whether the dog had a history of viciousness or if the owner knew of such viciousness 2. There are specific exceptions, particularly for governmental agencies using dogs in military or police work 2.

The rule

The owner of any dog is liable for damages suffered by any person bitten by the dog while in a public place or lawfully in a private place, including the owner's property, regardless of the dog's past viciousness or the owner's knowledge of it 2. A person is lawfully on private property if they are performing a duty required by law or are on the property by express or implied invitation of the owner 2.

How it applies

To establish a claim under this rule, a plaintiff must prove four essential factual elements: 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 was a substantial factor in causing the harm 1. The statute explicitly states that liability applies regardless of the dog's former viciousness or the owner's knowledge of such viciousness 2. This means that even if an owner believed their dog was gentle and had never bitten anyone before, they can still be held liable for a bite 2. A person is considered lawfully on private property if they are performing a duty imposed by state or federal law, including postal regulations, or if they are there by the owner's express or implied invitation 2.

There are specific exceptions to this strict liability rule for governmental agencies 2. A governmental agency using a dog in military or police work is not liable if the bite occurred while the dog was defending itself from an annoying, harassing, or provoking act, or assisting an employee in apprehending or holding a suspect with reasonable suspicion of criminal activity, investigating a crime, executing a warrant, or defending a peace officer or another person 2. However, this exception does not apply if the bite victim was not involved in the act that prompted the dog's use 2. Furthermore, the governmental agency must have adopted a written policy on the necessary and appropriate use of a dog for such work for the exception to apply 2.

What this does not cover

The provided sources do not cover liability for injuries caused by a dog that are not bites, such as being knocked down by a dog. The sources also do not detail potential defenses an owner might raise beyond the specific governmental agency exceptions. For instance, the sources do not discuss whether comparative negligence or assumption of risk might apply in dog bite cases. Additionally, the sources do not address liability for dog bites that occur on property designated as a shelter during an emergency, or the specific liability of owners of guide, signal, or service dogs beyond general property damage 5, 8. The sources also do not cover situations where a dog kills or injures livestock or poultry 6.
