Can trespassers sue for dog bites?

On Behalf of | Oct 15, 2025 | Personal Injury

Dog bites are serious and traumatic events that often lead to injuries and costly medical bills. In California, dog owners are liable for damages if their dog bites someone who is lawfully on public or private property. Now, the rules change significantly if you are bitten while trespassing on a private property.

How does trespassing affect dog owner liability?

Strict liability in California, where a party may be liable even if they were not negligent, applies only when the bite victim is in a public area or lawfully on private property such as the dog owner’s home or yard. If you were trespassing, you do not have this automatic protection since you had no legal right to be there.

Due to the circumstances, you may not rely on the state’s strict dog bite law to hold the owner responsible. Instead, you must prove that the dog owner was negligent.

How can you prove that a dog owner was negligent?

To be successful in your dog bite claim as a trespasser, you must prove that the owner acted carelessly. Negligence means the dog owner failed to act as a reasonable person would under similar situations. You may establish negligence if the dog owner:

  • Failed to control the dog despite knowing that it could pose a danger
  • Ignored warning signs like aggressive behavior or previous bites
  • Did not properly secure the premises or property despite knowing the risks
  • Created unsafe conditions that increased the chance of an attack

All dog owners have the responsibility not to create an unreasonable risk of harm to anyone. If they ignored this duty and you were injured as a result, they may still be held responsible.

Other legal factors that may affect your claim

California courts may also look at surrounding circumstances that can reverse your negligence claim, including whether:

  • You provoked the dog to behave in a way that triggered the attack.
  • You ignored the risk by knowingly entering the property illegally.
  • Your actions resulted in the injury, leading to reduced damages under the comparative fault rules.

These factors can greatly influence how much, if anything, you can recover.

Trespassing complicates, but does not close your case

Trespassing limits your protections under California’s dog bite law, but it does not automatically eliminate all liability. Dog owners still have a responsibility to act reasonably and prevent any foreseeable harm. Understanding these distinctions helps you protect your rights and seek fair recovery for your injuries.
