Dangerous Dog Proceedings in New York in New York, NY Agriculture and Markets Law 123 Step by Step

A dangerous-dog case is not the injury claim. It is a separate proceeding about the animal, with its own filing route, its own five-day calendar, its own standard of proof and its own penalty schedule, and in New York City a parallel administrative track that moves even faster.

What the statute means by a dangerous dog

Agriculture and Markets Law 108(24) sets three alternative descriptions. The first is a dog that without justification attacks a person, companion animal, farm animal or domestic animal and causes physical injury or death. The second is a dog that behaves in a manner a reasonable person would believe poses a serious and unjustified imminent threat of serious physical injury or death. The third covers a dog that without justification attacks a service, guide or hearing dog and causes physical injury or death. Police work dogs are excluded. Subdivision 28 defines physical injury as impairment of physical condition or substantial pain, and subdivision 29 defines serious physical injury to include protracted disfigurement or protracted loss or impairment of the function of a bodily organ.

How the proceeding starts and how fast it moves

Any person may make a complaint about an attack to a dog control officer or police officer, who may then bring a sworn complaint before a municipal judge or justice. On probable cause the court may order the dog seized pending the outcome. Section 123 requires the hearing to be held within five days on not less than two days' written notice to the owner. The petitioner must establish the dog is dangerous by clear and convincing evidence, a higher standard than the preponderance used in a civil injury case, which is one reason an adverse finding is useful in a later claim while the absence of one proves comparatively little.

The orders a judge may impose

A dangerous-dog finding carries mandatory neutering and microchipping. Beyond that, section 123 lets the court impose one or more further measures: evaluation by a certified applied behaviorist at the owner's expense with any recommended training, secure humane confinement, restraint in public on a leash held by a person at least twenty-one years old, muzzling when in public, or maintenance of a liability insurance policy the statute caps at one hundred thousand dollars for personal injury or death. Euthanasia or permanent confinement is reserved for aggravating circumstances. A euthanasia order is stayed thirty days, and an appeal is taken by filing a notice of appeal within thirty days.

Defenses the statute writes into the case

Section 123 recognizes justification. There is no dangerous-dog finding where the injured person was committing a crime against the owner or a member of the owner's family, was tormenting, abusing or assaulting the dog, or had done so in the past, or where the dog was responding to pain or injury, or was protecting itself, its owner, a member of its household, or its offspring. Those defenses shape the underlying facts a civil file needs. If a claim will later be contested on comparative fault under CPLR 1411, the testimony given at a hearing held within days of the incident will already be on the record.

Penalties, and what they do to the claim

The penalty ladder runs by injury and history. An owner who negligently permits a dog to bite and cause physical injury faces a civil penalty of up to four hundred dollars. Where the injury is serious physical injury the penalty rises to fifteen hundred dollars, and the statute allows that amount to be reduced by restitution the owner pays for unreimbursed medical expenses, lost earnings and other damages. Where a dog already adjudicated dangerous is negligently permitted to bite and cause serious physical injury, the offense is a misdemeanor punishable by a fine of up to three thousand dollars, up to ninety days, or both. Killing a person lawfully present is a class A misdemeanor.

The New York City track, and why it is faster

Inside the five boroughs the Health Code adds an administrative route. Section 161.07 lets the Department make a preliminary determination that a dog is dangerous, weighing the circumstances, the nature and severity of the injuries and any prior bite history, with a behaviorist assessment when needed. The petition and notice of hearing are mailed no later than fifteen days after the dog enters a shelter, and the hearing at the administrative trials office is scheduled no more than twenty days after mailing. A dog that caused severe injury, defined in 161.02 as at least a broken bone or a disfiguring laceration requiring multiple stitches or cosmetic surgery, stays in the shelter until an administrative law judge reports it is not dangerous. Section 123(12) confirms none of this displaces a civil claim.

Medical costs and the rest of the claim are not the same question

New York Agriculture and Markets Law §123(10) makes the owner or lawful custodian of a dangerous dog strictly liable for medical costs resulting from an injury caused by that dog.

Why it matters: That medical-cost rule is narrower than many people expect. A claim for pain, lost income or other damages still commonly depends on proof that the owner knew or should have known the dog had dangerous or vicious tendencies, so the file must preserve both treatment evidence and proof of prior behavior.

A bite report is due within 24 hours

NYC Health requires any type of animal bite to be reported within 24 hours of the event, and the city coordinates follow-up with the animal, owner and person bitten to assess rabies risk.

Why it matters: The Health Department report is a time-stamped public-health record that can help identify the dog and owner. It should be made promptly alongside medical care, while the separate evidence of notice, prior behavior and property control is preserved.

Reported bites reached a ten-year high in 2024

NYC Health reported 3,814 dog bites to city residents in 2024, the highest count of the 2015-2024 period, 51% above the 2,525 reported in 2020 and 28% above the 2,984 reported in 2016.

Why it matters: The citywide count underscores why a prompt Health Department report and a careful evidence record matter. A report addresses public-health follow-up; a civil claim still needs facts about the dog's prior behavior, the owner's notice and, in a building, any party with control.
