New York Dog Bite Laws: Liability, Dangerous Dog Rules, and Insurance

What New York 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.

Who pays when a dog bites — the New York rule

New York has no bite statute making an owner automatically liable for every bite. Liability runs through case law that changed recently.

The old rule, from Bard v. Jahnke, 6 N.Y.3d 592 (2006), was strict liability tied to knowledge: you were liable only if you knew or should have known your dog had violent tendencies, and that was the only theory available. On April 17, 2025, the Court of Appeals overruled that limit in Flanders v. Goodfellow (2025 NY Slip Op 02261) and added a second track, ordinary negligence. A person bitten by your dog now can pursue you either way: showing your dog's known history to claim strict liability, or, with no history at all, showing you failed to use reasonable care, such as leaving a door open.

A narrower rule layers on top: under N.Y. Agric. & Mkts. Law § 123(10), a dog a court has already declared dangerous carries automatic strict liability for medical and vet costs from any later injury, though not full personal-injury damages. This does not apply if the injured person was committing a crime, abusing the dog, or the dog was acting in self-defense (§ 123(4)). Whether these exceptions also limit an ordinary negligence claim is unsettled in the statute text.

How a dog gets designated dangerous

New York defines a dangerous dog in § 108(24) as one that, without justification, attacks and injures or kills a person, another animal, or a service, guide, or hearing dog, or that poses an imminent threat of serious injury or death. Police dogs on duty are excluded.

A witness, dog control officer, or police officer can file a sworn complaint with a municipal judge, who can seize the dog pending a hearing held within five days on two days' notice to the owner. The complainant must prove the dog is dangerous by clear and convincing evidence, a higher bar than most civil cases.

If the dog is found dangerous, § 123(2) requires spaying or neutering and microchipping, plus at least one more condition the judge picks: behavioral evaluation, secure confinement, adult leashing in public, muzzling in public, or liability insurance.

Insurance requirements

New York does not require liability insurance for dog owners statewide. The only insurance provision applies after a specific dog has gone through the hearing above and been found dangerous, and even then a judge need not order it. It is one of five options in § 123(2), capped at $100,000 if ordered, with no state-set minimum.

For ordinary owners with no dangerous-dog finding, state law sets no insurance mandate. Localities may add their own licensing or insurance rules, so long as those rules are breed-neutral and no less strict than state law.

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.
