North Dakota Dog Bite Laws: Liability, Dangerous Dog Rules, and Insurance
What North Dakota law expects from you as a dog owner — who pays after a bite, how a dog gets designated dangerous, and whether the state requires liability insurance. Every citation links to the official statute.
This page is not legal advice. It summarizes North Dakota state law as of 2026-07-13. Laws change and cities add their own rules — personally check the official statutes linked below, and talk to a licensed North Dakota attorney before acting on anything that matters.
| Liability rule | One-bite (owner knowledge) rule |
|---|---|
| Bite statute | common law (negligence + scienter); N.D. Cent. Code § 42-03 covers only "dogs as public nuisance," not bite-injury damages |
| Dangerous-dog statute | none found (no statewide dangerous/vicious dog chapter; municipalities regulate under N.D. Cent. Code § 40-05-01(22)) |
| Insurance requirement | No statewide requirement found |
Who pays when a dog bites: the North Dakota rule
North Dakota has no statute that makes a dog owner automatically liable for a bite. The Century Code's nuisance title has just one dog-specific chapter, Chapter 42-03, and it treats dogs as a public nuisance, not a bite-injury issue (N.D. Cent. Code Ch. 42-03). Its only remedy is a court order to kill a dog after a second complaint and hearing, and it awards no damages to a bitten person.
Because no bite-specific statute exists, North Dakota courts apply the common-law one-bite rule. An injured person generally has to show your dog had a dangerous or vicious tendency and that you knew or should have known about it. The North Dakota Supreme Court set this standard in Sendelbach v. Grad (1976), rejecting strict liability in favor of this knowledge-plus-negligence test. In practice, a first bite from a dog with no known history of aggression does not make you automatically liable. A prior bite, or other reason to know your dog was dangerous, makes a negligence claim much stronger.
No statute spells out a trespasser or provocation defense for dog bites, so that rests on general premises-liability principles rather than a confirmed statute. This research also found no statewide leash law in the titles it checked, so it is unresolved whether leash rules are set only at the local level or whether a statewide provision exists elsewhere in the code. A separate strict-liability rule covers livestock, not people: under N.D. Cent. Code § 36-21-11, you owe damages if your dog kills, wounds, or chases someone else's sheep, other domestic animal, or poultry.
How a dog gets designated dangerous
North Dakota has no statewide dangerous-dog or vicious-dog law: no state designation process, no hearing standard, and no statewide list of obligations such as confinement, muzzling, signage, or registration. Instead, the state hands dog regulation to cities. N.D. Cent. Code § 40-05-01(22) authorizes municipalities to license dogs and regulate how they are kept, including restricting or destroying a dog for public safety, though license fees are waived for assistance dogs.
Whether your dog can be designated dangerous, and what follows, depends on your city or county's ordinance.
Insurance requirements
North Dakota law does not require dog owners to carry liability insurance or post a bond statewide. This research checked every dog-related chapter in state law and found no insurance or bonding mandate, even for a dog a city has designated dangerous. Cities may also set their own insurance requirements under their licensing power.
The closest thing to a financial-responsibility rule in state law is a cost-recovery provision, not an insurance mandate. Under N.D. Cent. Code § 23-36-09, you are liable for quarantine, veterinary costs, and any postexposure rabies treatment a bitten person receives, if your dog was not licensed, confined, or vaccinated as required by law, with no dollar cap set.
Worth knowing
- No statewide breed rule either way. North Dakota has not banned breeds or blocked cities from doing so, and at least one city has its own breed-specific ordinance.
- Rabies quarantine runs through a statewide framework under the Department of Health and Human Services (N.D. Cent. Code Ch. 23-36). The department can seize and quarantine a dog that bit or exposed someone, and a licensed veterinarian must examine a confined dog at the owner's expense; seizure on private property usually requires a warrant.
- Violating a quarantine order is an infraction. The nuisance chapter itself creates no crime; its only sanction is a court-ordered killing after a second complaint.
- Whether a statewide leash law exists is unresolved. This research found none in the nuisance or livestock titles, but did not rule one out elsewhere.
Other states
Rules change at the state line — a dog that is fine at home can put you under a different liability standard on vacation. See the full 50-state table.
