The One Bite Rule in North Dakota: How Dog Bite Liability Actually Works

If a dog bites you in North Dakota, the path to compensation is not as straightforward as it is in most other states. North Dakota handles dog bite liability differently from most states — there is no dedicated dog bite statute on the books, which means the rules come from court decisions, negligence law, and a patchwork of local ordinances. That legal gap puts more of the burden on you as a victim to build your case carefully.

At the center of that framework is the one bite rule, a common-law doctrine that shapes whether a dog owner can be held responsible for your injuries. Understanding how it works in North Dakota — and where its limits are — can make a real difference in whether you recover compensation or walk away empty-handed.

Key Insight: North Dakota has no strict liability dog bite statute. Your case will be decided by negligence principles, local ordinances, and case law — not a single clear-cut statewide rule.

Does North Dakota Follow the One Bite Rule?

North Dakota is one of 14 states that follow the one bite rule. Because North Dakota has no specific statute for dog bites, the courts use the one bite rule — meaning a dog owner cannot be held liable the first time a dog bites or attacks someone, under the assumption that the owner did not know the animal was dangerous.

However, calling it a simple “one free bite” rule is a slight oversimplification of how North Dakota courts actually apply the doctrine. North Dakota permits a dog bite victim to recover compensation if they can prove that the dog owner knew the dog was vicious and was negligent in not preventing the accident — and there is no strict liability for knowledge of dangerousness alone when unaccompanied by owner negligence.

The landmark case Sendelbach v. Grad (1976) 246 NW 2d 496 established that dog bite liability in North Dakota is based not on scienter (knowledge) alone under the common law, but on a combination of scienter and negligence. That ruling remains the foundation of every dog bite claim in the state today.

How the One Bite Rule Works in North Dakota

The one bite rule means a dog owner cannot be held liable if it is the first time a dog showed aggressive behavior like biting or attacking, because it holds the assumption that the owner did not know the dog was dangerous. However, after that first bite, the owner must presume the dog is dangerous — making any further aggressive behavior negligence on the part of the owner.

In practice, this creates a two-part test. You need to show both that the owner had knowledge of the dog’s dangerous nature and that the owner failed to act reasonably on that knowledge. The Sendelbach court approved a jury instruction stating: “If the dog’s traits or propensities are of a nature likely to cause injury the owner must exercise reasonable care to guard against and to prevent injuries or damages which are reasonably to be anticipated from the dangerous or vicious propensity of the dog.”

In Hart v. Kern (1978) 268 NW 2d 136, the North Dakota Supreme Court further developed the negligence guidelines for dog bite cases. In that case, two dogs were known to fight each other, and the defendant’s dog got loose and attacked the plaintiff. The defendant knew the plaintiff was coming to the house and had tried to confine the dog in a garage — but the garage door was not fully shut. The court reversed summary judgment for the defendant, stating that a fact-finder must decide whether the owner’s knowledge of the dog’s ability to escape and his failure to warn the plaintiff amounted to wanton or willful negligence.

Important Note: North Dakota’s one bite rule requires more than just proving a prior bite occurred. You must also show the owner failed to take reasonable precautions after gaining that knowledge.

What Victims Must Prove Under the One Bite Rule in North Dakota

Because North Dakota merges the knowledge and negligence requirements, your claim rests on three distinct elements. You must prove the existence of a vicious propensity to bite, the dog owner’s knowledge of that vicious propensity, and the dog owner’s negligence in failing to prevent the bite injuries.

Here is how each element breaks down in a practical claim:

• Ownership or control: The person being held liable must have been the dog’s owner, keeper, or harborer at the time of the attack. In North Dakota, this may extend to anyone who had custody or control over the animal.
• Prior knowledge of dangerousness: Under the one bite rule, you must establish that the owner had knowledge that the dog had previously bitten someone or exhibited aggressive behavior that put the owner on notice of the risk.
• Negligence: You must show that the dog’s owner owed a duty to prevent the animal from causing injuries, that the owner failed to uphold that duty, and that this failure was the direct cause of your injuries and damages.

North Dakota also uses a modified comparative negligence system with a 50% bar, allowing victims to recover damages only if they are less than 50% at fault for the incident. That means your own conduct during the incident can directly affect — or eliminate — any award you receive.

What Counts as Prior Knowledge in North Dakota

Prior knowledge is often the most contested element of a North Dakota dog bite case. Many people assume that “prior knowledge” means the dog must have bitten someone before — but the standard is broader than that. Owners are liable if their dogs have a known propensity for violent behavior, and the most obvious example is that the dog has bitten someone before — but it is far from the only one.

Evidence courts and attorneys look for to establish prior knowledge includes:

• A documented history of biting or attacking a person or other animal
• Prior complaints or reports made to local animal control
• Growling, snapping, lunging, or other threatening behavior witnessed by neighbors or visitors
• The owner’s own statements acknowledging the dog’s aggression
• Veterinary or training records noting aggressive tendencies
• A “Beware of Dog” sign posted by the owner (which can suggest awareness of danger)

If a dog owner violated a local ordinance, that can be used as evidence of negligence. And if the dog had already been reported before, that can strengthen your case even more. Cities like Fargo and Bismarck maintain their own dangerous-dog registries and ordinances, so checking with local animal control is a practical first step after any bite.

The concept of “scienter,” or knowledge of the dog’s dangerous tendencies, is central to how North Dakota courts evaluate these claims. Even if no bite occurred previously, a pattern of aggressive behavior that a reasonable owner would recognize as dangerous can satisfy this element.

Exceptions and Defenses to the One Bite Rule in North Dakota

Even when you can prove knowledge and negligence, a dog owner may still raise defenses that reduce or eliminate their liability. North Dakota recognizes several of these under its negligence framework.

Provocation

A common defense is provocation. If a person provoked the dog, leading to aggressive behavior, the owner might not be held liable. Provocation can include teasing, hitting, or harassing the dog, and this defense requires substantial evidence, including thorough documentation and witness testimonies.

Provocation can include a range of behaviors from teasing and taunting to physically harming the dog. The key element is that the dog’s reaction must be a direct response to the victim’s actions. Courts look closely at the context — accidentally startling a dog is treated very differently from deliberately tormenting one.

Trespassing

Another defense arises from trespassing incidents. If someone unlawfully enters a property and is bitten by a dog, the owner may not be liable, as North Dakota’s legal framework recognizes property owners’ rights to protect their premises. The circumstances of the trespass, such as the trespasser’s intent and actions, are critical in determining whether this defense applies.

Individuals like mail carriers, delivery drivers, and utility workers are generally not considered trespassers, since they have an implied license to be on the property. A child who wanders onto a neighbor’s yard is also evaluated differently than an adult who ignores posted warning signs.

Assumption of Risk

The assumption of risk defense argues that the injured person voluntarily and knowingly accepted the risk of being bitten. This is most commonly applied to individuals who work with animals professionally, such as veterinarians, dog groomers, and kennel employees.

Comparative Fault

North Dakota follows a modified comparative negligence rule in personal injury cases. If you are found to be partially at fault — for example, by provoking the animal or trespassing on private property — your awarded compensation might be reduced by your percentage of fault. If you are found to be 50% or more at fault, you may be barred from recovering any compensation at all.

Pro Tip: Even if a dog owner raises a provocation or trespass defense, the strength of your documentation — photos, medical records, witness statements, and animal control reports — can significantly offset those arguments.

Dog Owner Liability Beyond the One Bite Rule in North Dakota

The one bite rule is not the only legal avenue available to victims. Beyond the primary liability framework, North Dakota law may provide additional theories for holding dog owners accountable. Negligence claims, violations of local leash laws or animal control ordinances, and in some cases landlord liability can all serve as the basis for a dog bite injury claim.

When a dog owner violates a local animal control ordinance — such as a leash law or containment requirement — this violation may constitute negligence per se, creating a presumption of negligence that strengthens the victim’s case. This is particularly relevant in North Dakota’s urban areas, where city-specific codes carry real legal weight.

There is also one area where strict liability does apply regardless of prior knowledge. A North Dakota statute holds a dog owner automatically liable for certain damages and costs resulting from a bite in one specific circumstance: if the owner violated state law by failing to license, register, or protect the dog from contracting rabies through vaccination or confinement, the owner will automatically be liable to a bite victim for any medical treatment for potential rabies exposure.

Local ordinances in major cities add another layer. Under Fargo Municipal Code § 12-0117, a dog may be deemed dangerous if it has attacked or bitten a person or another animal without provocation, and owners of such dogs are required to meet specific conditions such as registration and confinement requirements. In Bismarck, under Title 3, Chapter 3-03 of the Bismarck Code of Ordinances, a dog that has bitten or attacked a person or animal without provocation may be declared dangerous, and owners must adhere to regulations that may include secure confinement, muzzling when off the owner’s property, and maintaining liability insurance.

It is also worth noting that liability is not limited to the dog’s registered owner. Under North Dakota law, numerous individuals, businesses, or entities could owe you damages for negligently failing to protect you from getting bitten. Negligence occurs when someone fails to exercise reasonable care by not keeping you safe from a dog — and liable parties could include an insurance company that issued liability coverage, such as homeowners insurance, to any of the above.

What to Do After a Dog Bite in North Dakota

The steps you take in the hours and days after a dog bite can directly shape the strength of your legal claim. Because North Dakota’s one bite rule requires you to prove the owner’s prior knowledge and negligence, building a clear factual record from the start is essential.

1. Seek medical attention immediately. Get your injuries treated and documented by a medical professional. Medical records are foundational evidence in any dog bite claim.
2. Report the bite to local animal control. Filing an official report creates a public record of the incident and may reveal prior complaints about the same dog. Many cities and counties in North Dakota have their own rules about dogs, including dangerous dog designations and what happens when a dog attacks someone.
3. Document everything. Photograph your injuries, the location of the attack, and any relevant conditions such as broken fencing, missing leashes, or absent warning signs.
4. Gather witness information. Collect names and contact details from anyone who saw the attack or who has knowledge of the dog’s prior behavior.
5. Research the dog’s history. Investigate the dog’s history, including any prior reports to animal control, and request records from the city or county about leash law violations or dangerous dog designations.
6. Be mindful of the statute of limitations. In North Dakota, you have six years from the date of your dog bite to file a personal injury lawsuit under N.D. Cent. Code § 28-01-16 — but waiting can hurt your case. Evidence fades and witnesses forget, so acting promptly is always the better approach.
7. Consult a personal injury attorney. Given the complexity of proving knowledge and negligence without a dedicated statute, legal guidance is valuable. An attorney can help you navigate local ordinances, insurance claims, and the evidentiary demands of a one bite rule case.

Pro Tip: Even if you are unsure whether the dog has bitten before, report the incident to animal control anyway. Your report may be the first on record — and it protects the next potential victim by creating the documented history that a future claim would require.

Dog bite cases in North Dakota are genuinely more complex than in strict liability states, but that does not mean victims are without recourse. The one bite rule places a higher evidentiary bar on your claim, but with thorough documentation and a clear understanding of what the law requires, you can build a strong case.
