Oregon Dog Bite Law: Liability, Insurance, and Deadlines

Under Oregon dog bite law, the owner of a dog that injures someone is strictly liable for the victim’s economic losses — medical bills, lost wages, and similar out-of-pocket costs — without the victim having to prove the owner was careless or that the dog had bitten before. Compensation for pain, emotional distress, and other non-monetary harm is available too, but it requires proving either that the owner knew the dog was dangerous or that the owner was negligent. Claims must be filed within two years of the bite.

What You Can Recover Without Proving Fault

ORS 31.360 removes the hardest part of most injury cases. A bite victim does not have to show the owner did anything wrong, and the owner cannot defend by claiming the attack was unforeseeable. The tradeoff is scope: this automatic recovery is limited to economic damages.¹

Oregon defines economic damages in ORS 31.705 as objectively verifiable monetary losses. For a dog bite claim, that typically includes:²

Emergency treatment, surgery, nursing care, rehabilitation, and other medical and hospital charges
Wages lost during recovery and any long-term reduction in earning capacity
The cost of hiring someone to handle household tasks you can no longer perform
Repair or replacement of clothing, eyeglasses, or other property damaged in the attack

Keep every receipt, bill, pay stub, and estimate. These are the numbers that drive the recoverable amount.

Recovering Pain and Suffering

Noneconomic damages — pain, mental suffering, emotional distress, humiliation, loss of companionship, and interference with daily life — are not covered by the strict liability statute.² To collect for those harms, the victim needs a separate legal theory.

The One-Bite Rule

Oregon follows the common-law principle sometimes called the one-bite rule. If the owner knew or should have known that the dog had dangerous tendencies, the owner is liable for all damages, including pain and suffering. Prior bites are the clearest evidence, but growling at strangers, lunging at other animals, or repeatedly escaping a yard to chase people can also show the owner was on notice. If the dog had no prior signs of aggression, this path is hard — which is exactly the gap ORS 31.360 closes for medical bills and lost wages.

General Negligence

A victim can also argue that the owner failed to use reasonable care, regardless of what the dog had done before. Letting the dog off-leash in violation of a local ordinance, failing to maintain a secure fence, or ignoring clear warning signs in the moment can all support a negligence claim. Proving negligence opens the door to both economic and noneconomic damages.

Defenses the Owner Can Raise

ORS 31.360 preserves provocation as a defense along with “any other defense that may be available.”¹ Two come up most often.

Provocation

If the victim provoked the dog, the owner may escape liability. Provocation can be intentional, like taunting or hitting the animal, or unintentional, like stepping on its tail. The question is whether the dog’s response was proportionate. A serious bite in reaction to a minor, accidental contact can still produce liability if the reaction was disproportionate or the owner knew the dog overreacted to small triggers.

Trespassing

A trespasser has a weaker claim. ORS 609.115 explicitly excludes anyone trespassing on premises from which the keeper may lawfully exclude others from the strict liability protection that applies to already-classified potentially dangerous dogs.³ A social guest, a mail carrier, or someone walking up a driveway for a legitimate purpose is lawfully present. Someone who climbs a fence into a backyard is not.

Potentially Dangerous and Dangerous Dog Classifications

Oregon sorts problem dogs into two tiers, and the classification matters for both civil liability and the keeper’s criminal exposure.

Potentially Dangerous

Under ORS 609.035, a dog is potentially dangerous if, without provocation, it menaces a person while off the keeper’s property, inflicts a physical injury that is not a “serious physical injury,” or injures or kills livestock or a domestic animal off the keeper’s property.⁴ Such a dog is a public nuisance under ORS 609.095, which can trigger a court-imposed restriction order requiring confinement, muzzling in public, or other controls. Violating the order is itself a separate offense.⁵

Once a dog has been officially found potentially dangerous and the keeper has been found in violation of ORS 609.095, the stakes rise. If that dog later injures a person or damages property, the keeper is strictly liable for all resulting economic damages, with no foreseeability defense. The only exceptions are when the victim provoked the dog, assaulted the keeper, or was trespassing.³

Dangerous

The dangerous dog label under ORS 609.098 is reserved for the most serious cases. A dog qualifies if it inflicts serious physical injury or kills a person without provocation and in an aggressive manner, repeats potentially dangerous behavior after the keeper was already found in violation for a prior incident, or is used as a weapon in a crime.⁶

Criminal Penalties for the Keeper

ORS 609.990 attaches criminal consequences that escalate with severity:⁷

A public nuisance violation under ORS 609.095 is a Class B violation, carrying a fine but no jail time
Maintaining a dangerous dog under ORS 609.098 is a Class A misdemeanor, punishable by up to one year in jail
Maintaining a dangerous dog that kills a person is a Class C felony, which carries a potential prison sentence

The crime of maintaining a dangerous dog requires criminal negligence — a failure to be aware of a substantial and unjustifiable risk that the dog would cause harm.⁶

Reporting a Bite and the 10-Day Quarantine

A dog bite must be reported to the county health department within one working day. The victim, a parent or guardian if the victim is a minor, or the attending physician is responsible for filing. The dog is then quarantined for 10 days as a rabies precaution; the same rule applies to cats and ferrets that bite a person. Failing to report or refusing to quarantine the animal creates additional legal exposure for the keeper and muddies the administrative record if a civil claim follows.

Who Actually Pays: Homeowners and Renters Insurance

Most homeowners and renters policies include liability coverage that extends to dog bites. Typical limits run between $100,000 and $300,000, covering the injured person’s medical bills, lost wages, and legal costs up to the policy cap. Anything above the limit comes out of the owner’s own assets. An umbrella liability policy, if the owner carries one, sits above the homeowners limit and can absorb a larger claim.

A single bite reshapes the owner’s insurance picture quickly. Insurers commonly raise the premium, exclude the specific dog from future coverage, or decline to renew altogether. Some carriers keep restricted breed lists and will not write a policy for owners of certain breeds in the first place. Documented behavior training or consistent muzzling and restraint can help keep coverage, but nothing guarantees it. If the policy excludes the dog or the owner has no insurance at all, the victim is chasing personal assets.

Two Years to File

Oregon’s statute of limitations for personal injury claims, including dog bites, is two years from the date of injury under ORS 12.110.⁸ Miss the deadline and the case will almost certainly be dismissed, no matter how strong the evidence. For injuries to a minor child, the deadline may be extended because the statute of limitations is typically tolled until the child reaches the age of majority, though the specifics depend on the circumstances and the applicable tolling provisions.

Two years sounds generous. In practice, the early months are when witness memories are freshest, veterinary and medical records are easiest to pull, and the dog’s behavioral history is clearest. Moving early also preserves the option to settle before filing suit.

Tax Treatment of a Settlement

Compensation for physical injuries from a dog bite is generally not taxable under federal law. Section 104(a)(2) of the Internal Revenue Code excludes damages received on account of personal physical injuries or physical sickness from gross income, whether paid as a settlement or a judgment.⁹ The exclusion covers medical expenses, lost wages tied to the physical injury, and emotional distress stemming directly from it. Two exceptions matter:¹⁰

Punitive damages are always taxable, even when awarded alongside a physical injury claim
If you previously deducted injury-related medical expenses and later get reimbursed for them in a settlement, the reimbursed portion is taxable to the extent the deduction gave you a tax benefit

Interest that accrues on a settlement or judgment is taxable as ordinary interest income. For a sizable settlement, a tax professional can sort out which pieces are excludable and which have to be reported.
