Idaho Dog Bite Law

How dog bite liability works in Idaho

For more than a century Idaho was a scienter state. Under a line of cases going back to 1909, a dog's owner paid for a bite only if they knew or should have known the dog was dangerous³. In 2016 the Legislature rewrote the dog chapter of Title 25. It added a civil-liability clause to the new dangerous-dog section, § 25-2810(11), and said that no earlier dangerous-dog finding is needed before a victim can recover¹. In Boswell v. Steele (Idaho 2018), a case about a 2011 bite, the Idaho Supreme Court noted that the Legislature had acted "to supplant the common law theories of liability" when it adopted § 25-2810².

The clause sits inside a criminal statute, and it has limits. It does not cover trespassers. It does not apply when the dog was provoked or "otherwise justified" under the provocation list in § 25-2810(5): a dog defending its owner, a person committing a crime on the owner's property, past torment of the dog, a working herding or hunting dog, a service animal, or someone breaking up a dog fight¹. Police dogs used carefully are exempt¹². As of October 2026 no published Idaho appellate opinion has applied subsection (11), so how courts will read its edges is still open.

Fault is compared under § 6-801. The bar is at equal fault: you recover only if your share is less than the owner's⁴. In Boswell the court applied that rule to a strict-liability dog claim².

Idaho borders six states with different rules. To compare it with Washington, Oregon, Nevada, Utah, Wyoming and Montana, see the national table.

The Idaho dog bite statute

A dog that physically attacks, wounds, bites or otherwise injures a person who is not trespassing makes its owner, or anyone who has accepted responsibility as the dog's possessor, harborer or custodian, or both, civilly liable for the injuries¹. The rule does not apply if the dog was physically provoked or justified under the list in § 25-2810(5), or was a police dog used as § 25-2808 allows¹¹². A prior finding that the dog is dangerous or at risk is not a prerequisite to liability¹.

• Law: Idaho Code § 25-2810(11) (Dangerous and at-risk dogs (civil liability clause)), enacted 2016; last changed 2019: Laws 2019, ch. 300, amended § 25-2810; subsection (11) has kept its 2016 rule
• Injuries covered: Any injury the dog causes (bites, knock-downs, chases)
• Where: Public places, or lawfully on private property
• Who is liable: The owner, or a keeper or harborer
• Damages: All damages, under the ordinary rules

Other ways to prove liability

Before 2016, an owner of a non-trespassing dog was liable only if they "knew or should have known" of its vicious or dangerous tendencies. A non-owner who controlled the property could be liable on the same notice³. Once that knowledge was shown, the owner was liable even with ordinary care: "Reasonable care is simply not an element" of the claim². These theories still matter for bites before the 2016 statute and for injured trespassers. A claim of negligence per se for breaking a dog-control law needs proof that the defendant actually harbored the dog³. A city ordinance can also create its own claim: Boswell treated Pocatello's dangerous-animal ordinance as a separate cause of action².

Defenses owners raise

Trespassing

The statute covers only a person "who is not trespassing"¹. A trespasser falls back on the common-law rules, and one who was committing a crime on the owner's property also counts as having provoked the dog under § 25-2810(5)(b)¹.

Provocation

No liability under the statute if the dog was "physically provoked" or justified under § 25-2810(5). That list includes willfully tormenting, abusing or assaulting the dog now or in the past, a dog responding to pain or protecting puppies, and stepping between fighting animals¹. The list is open-ended. It also covers any act a reasonable person with common knowledge of dog behavior would expect to set off a bite by an ordinary dog¹.

Other defense

A dog defending a person nearby from an attack, a working hunting, herding or predator-control dog on duty where it lawfully works (public lands included), and a trained service animal are all within the justified-provocation list, so the statute does not reach them¹.

Police dogs

The state, a city or county, and their peace officers are not civilly liable for injury by a dog trained for law enforcement when it is used "reasonably and carefully" to find, apprehend or arrest a suspect or keep public order¹².

Assumption of risk

Your own conduct reduces or bars the award under § 6-801, which Idaho applies to strict-liability claims⁴². A person who ignored a "Beware of Dog" sign, or reached for a dog they knew had bitten before, can expect the owner to argue fault.

Shared fault

Modified comparative fault (barred at 50%) (Idaho Code § 6-801).

Your damages are cut by your share of fault, and you recover nothing if your fault is as great as the defendant's⁴. In Boswell v. Steele the Idaho Supreme Court held that § 6-801 applies to strict-liability dog claims under the common law. It also held that it did not apply to the claim created by the Pocatello ordinance, where provocation was a complete defense instead². No appellate court had ruled on § 25-2810(11) itself as of October 2026.

How the five fault systems compare: provocation, trespass and shared fault.

Idaho dog bite statute of limitations

2 years (Idaho Code § 5-219(4))

Suit must be filed within two years of the bite. The claim accrues on the day of the injury, and later complications do not extend it⁵. If a city, county or other political subdivision is responsible (a county shelter dog, for example), a written claim must be filed with its clerk within 180 days, and suit must follow within two years⁸⁹.

Children. The two years do not run while the injured person is under 18. Tolling for minority is capped at six years, so a child bitten at age 5 has until age 13⁶⁷. A child bitten at 16 has until age 20⁶⁷.

Damages

You can recover medical costs, lost wages and other economic losses, plus pain and suffering, scarring and emotional harm, under § 25-2810(11) and at common law¹². Noneconomic damages are capped at $250,000, adjusted every July 1 by the change in Idaho's average annual wage. The cap does not apply to willful or reckless misconduct or to a felony proven beyond a reasonable doubt¹⁰. Punitive damages need clear and convincing proof of oppressive, malicious or outrageous conduct. They must be added by court motion, not in the first complaint, and are capped at the greater of $250,000 or three times compensatory damages¹¹. In a criminal dangerous-dog case the court can also order restitution for medical bills and property damage¹.

Landlords and property owners

In Bright v. Maznik, 162 Idaho 311, 396 P.3d 1193 (2017), a tenant's dog attacked a visitor. The Idaho Supreme Court held that a landlord may owe a duty only if it had notice of the dog's "vicious or dangerous propensity"³. The property manager had asked the tenants' former landlord about "dog issues" and heard no concerns, and no one had complained about the dog. That was not notice, and summary judgment for the landlords stood³. Owning the land and letting a tenant keep a dog does not make the landlord a "harborer"³. Subsection (11) does reach a person who "accepted responsibility" as harborer or custodian, but that is the same kind of control test¹.

Insurance

No Idaho statute we found limits insurers' use of dog breed in homeowners or renters policies. The 2016 dangerous-dog law does not make owners of declared dogs carry liability insurance or a bond¹.

Boswell v. Steele: the last big common-law case

Stephen Boswell was bitten in 2011 by a Scottish terrier that had drawn blood twice before and lived behind a "Beware of Dog" sign. His case went up on appeal twice. In 2018 the Idaho Supreme Court ordered a new trial because the jury was never told that, under the common law, an owner who knows of a dog's vicious tendency is liable "regardless of whether the owner or custodian acted with ordinary care"². The court also held that comparative fault applies to that common-law claim but not to a claim under Pocatello's dangerous-animal ordinance². In a footnote, it observed that the 2016 statute had supplanted the common-law theories it had just explained². The case is still the best guide to how Idaho courts treat strict liability for dogs and the fault of the person bitten.

Bite reports and quarantine

Idaho's reportable-disease rule does not list dog bites. A provider who starts rabies post-exposure shots must report that to the Department of Health and Welfare or the public health district within one working day¹⁶. The Department tells anyone who is bitten to wash the wound and contact a healthcare provider and the local public health district, which decides whether the animal should be tested¹⁷. Cities add their own rules: Boise requires the owner of a dog that broke a person's skin to surrender it for quarantine¹⁸.

Under the state rule as amended effective July 1, 2026, a healthy dog that bit a person, vaccinated or not, must be managed under the supervision of a licensed veterinarian or a person designated by the Department of Agriculture, the health district or the Department of Health and Welfare. The owner must follow their instructions¹⁶. The rule text no longer sets a number of days¹⁶. A dog that cannot be managed that way is euthanized and its head is tested, and no one may destroy the head without authorization¹⁶. Local codes fill in the period: Boise requires veterinary confinement for 10 to 15 days after a bite¹⁸.

Dangerous-dog hearings, euthanasia orders and criminal penalties are covered on Idaho dangerous dog law.

Questions about Idaho dog bite law

Is Idaho a one-bite state?

Not since 2016. Section 25-2810(11) makes the owner or custodian liable for an unprovoked injury to someone who is not trespassing, and says no earlier dangerous-dog finding is required¹. The older rule, which required proof that the owner knew the dog was dangerous, still matters for bites before the statute and for trespassers³².

Does the Idaho statute cover a dog that knocks someone down without biting?

Its wording reaches a dog that "physically attacks, wounds, bites or otherwise injures" a person¹. The words "otherwise injures" suggest non-bite injuries are covered, but no Idaho appellate court had ruled on that as of October 2026. A negligence claim remains an alternative³.

My child was bitten in Idaho. How long do we have?

The two-year limit does not run while the child is under 18, but Idaho caps that pause at six years⁵⁶. A child bitten at 4 has until age 12; a child bitten at 17 has until 20⁶⁷. If a city or county is involved, the 180-day claim notice is a separate deadline⁸.

Can I sue the landlord of the dog's owner in Idaho?

Only in narrow cases. Bright v. Maznik requires notice of the dog's dangerous propensity, and owning the rental does not make a landlord the dog's harborer³. See the guide to landlord liability.

Will my Idaho dog be put down after one bite?

Not by the dangerous-dog law alone. A first bite without serious injury can only make the dog "at risk", and only a court can order euthanasia, after finding the dog "dangerous"¹. Separately, the rabies rule requires euthanasia only for a dog that cannot be managed under veterinary supervision¹⁶.
