Trespassing, Provocation & Owner Knowledge

By the FigureMyTax Editorial Team · How we calculate

Even California's strong strict liability statute isn't unconditional. A handful of real exceptions and defenses can reduce or entirely defeat an otherwise valid dog bite claim.

Trespassing removes strict liability

Cal. Civ. Code §3342 protects people in a public place or lawfully present on private property. If you were trespassing when bitten, strict liability doesn't apply, and you'd need to fall back on an ordinary negligence theory, which typically requires showing the owner acted unreasonably given what they knew or should have known about the dog.

Provocation is a complete defense

Under California law, provocation operates as a complete defense — not merely a partial reduction. If the victim's own conduct, such as teasing, hitting, or startling the dog, directly caused the bite, this can defeat the owner's strict liability entirely. This is a meaningfully stronger defense than a simple comparative-fault reduction.

A warning sign isn't enough

Posting a "Beware of Dog" sign does not automatically shield an owner from strict liability. California's statute contains no warning-sign exception, so a sign alone won't defeat an otherwise valid claim — the owner still needs an actual defense like trespassing or provocation.

Comparative fault still applies short of full provocation

Conduct that falls short of full provocation can still factor into California's pure comparative negligence framework, reducing the victim's recovery proportionally rather than eliminating it entirely — a meaningfully different outcome than the all-or-nothing provocation defense.

Narrow exceptions for working dogs

Cal. Civ. Code §3342(b) carves out specific exceptions for military and police dogs acting in the course of their official duties — these don't apply to an ordinary household pet.

This is general information, not legal advice. Whether an exception applies depends heavily on the specific facts. Confirm how these defenses might affect your case with a licensed California attorney.
