New York Dangerous Dog Law
In New York a dog bite usually means two separate processes: a 10-day rabies confinement run by the county health department, and, if someone files a complaint, a court hearing on whether the dog is a "dangerous dog"111. Only a judge can make that finding, on clear and convincing evidence, and euthanasia is limited to serious attacks1.

What happens first: the rabies confinement
The health side moves first. Health care providers must report a person's exposure to an animal suspected of rabies immediately, and the Department of Health asks everyone to report every animal bite to the county health department1112. The local health authority may then order the dog confined for 10 days, vaccinated or not, at the owner's expense11. The health authority sets the conditions and decides who keeps the dog, which can be the owner at home11. If the dog stays healthy for 10 days, it could not have transmitted rabies through the bite12. Outside New York City, every dog must be vaccinated against rabies, first by four months of age16; Public Health Law §§ 2140 to 2145 do not apply in the city15. See the national quarantine guide.
A bite does not by itself make a dog "dangerous" in the legal sense. That label requires a court proceeding.
Who can start a dangerous-dog case?
Anyone who saw an attack or a threatened attack on a person, a companion animal, a farm animal or a domestic animal can complain to the dog control officer or the police; for a child, an adult can act on the child's behalf1. The officer must tell the complainant they can start a court proceeding, and must start one personally if there is reason to believe the dog is dangerous1. The complaint is made under oath to a town, village or city judge or justice1. Dog control officers are appointed locally; the state Department of Agriculture and Markets regulates dog licensing and issues guidance to municipalities on dog control officers14.
If the judge finds probable cause, the judge orders the dog seized and held. Whether or not the dog is seized, a hearing must be held within five days, on at least two days' written notice to the owner1.
What counts as a dangerous dog?
Under § 108(24), a dangerous dog is one that, without justification, attacks a person or a companion, farm or domestic animal and causes physical injury or death; behaves so that a reasonable person would believe it poses a serious and unjustified imminent threat of serious physical injury or death; or attacks a service, guide or hearing dog and causes injury8. "Physical injury" means impairment of physical condition or substantial pain, so a minor bite can qualify8. Police work dogs on duty are excluded8.
The person bringing the case must prove dangerousness by clear and convincing evidence1. A dog cannot be declared dangerous if its conduct was justified: the victim was committing a crime against the owner or the owner's property, had tormented, abused or threatened the dog (now or in the past), or the dog was responding to pain or protecting itself, its owner or its household1. Testimony from a certified behaviorist or other expert is relevant to that question1.
What the court orders
After a dangerous-dog finding the judge must order the dog spayed or neutered and microchipped, plus one or more of: a behavior evaluation and training at the owner's expense, secure humane confinement, leashing in public by an adult of at least 21, muzzling in public, or liability insurance in an amount the court sets, up to $100,0001. The insurance figure is a ceiling, not a statewide minimum. The owner must also report the dog's presence under General Municipal Law § 209-cc1.
Can the court order the dog put down?
Only with an aggravating circumstance proven at the hearing: an unjustified attack that caused serious physical injury or death to a person; a known vicious propensity shown by an earlier unjustified attack on a person causing serious injury or death; or serious injury or death to an animal by a dog found dangerous for injuring an animal in the past two years1. Even then, the judge may choose permanent confinement instead1. See the national guide to dog bite euthanasia laws.
How to appeal
The owner can appeal the finding or the disposition order by filing a notice of appeal within 30 days of the final order, in the court that hears civil appeals for that county1. A euthanasia order cannot be carried out during those 30 days unless the owner waives the appeal in writing, and filing the notice stays it automatically1. For other orders, the owner has to ask the court for a stay1.
Fines and criminal charges
A negligent owner whose dog bites a person or a service, guide or hearing dog faces a civil penalty of up to $400; if a person suffers serious physical injury, up to $1,500, reduced by restitution the owner pays the victim1. If a dog already declared dangerous seriously injures someone through the owner's negligence, it is a misdemeanor with a fine of up to $3,000, up to 90 days in jail, or both1. If a dog already declared dangerous kills a person who was lawfully where they were, the owner is guilty of a class A misdemeanor whether or not the owner was at fault for the escape1. These penalties do not apply when the dog was defending someone against murder, robbery, burglary, arson, first-degree rape or kidnapping on the owner's property1. See dog bite criminal charges.
Civil liability and insurance after a finding
Once a dog has been declared dangerous, the owner or custodian is strictly liable for the medical costs of any later injury it causes1. Homeowners' insurers cannot cancel or surcharge a policy because of a dog's breed, but they may act on a dangerous-dog designation13.
Breed rules
New York forbids breed-specific dangerous-dog programs. Section 107(5) lets municipalities, New York City included, adopt programs stricter than the state's, but none may regulate dogs in a manner specific as to breed9. See breed-specific legislation.

New York rules in brief
Reporting. The State Sanitary Code requires every health care provider to report immediately to the local health authority any person exposed to an animal suspected of rabies; when no provider is involved, a parent reports for a child and an adult reports for themselves11. The Department of Health asks people to report all animal bites to the county health department, even when unsure about rabies12. Public Health Law §§ 2140 to 2145 do not apply in New York City15.
Euthanasia. A judge who finds a dog dangerous may order humane euthanasia or permanent confinement only on an aggravating circumstance: an unjustified attack causing serious physical injury or death, a previous unjustified attack on a person causing serious injury or death, or a serious attack on an animal within two years of an earlier dangerous-dog finding1. The order cannot be carried out during the 30-day appeal period, and a notice of appeal stays it automatically1.
Criminal penalties. An owner whose dog bites through the owner's negligence faces a civil penalty of up to $400, or $1,500 for serious physical injury1. If a dog already declared dangerous bites and causes serious physical injury through the owner's negligence, the owner commits a misdemeanor punishable by a fine up to $3,000, up to 90 days in jail, or both; if it kills a person who was lawfully where they were, the owner is guilty of a class A misdemeanor even if the dog escaped without the owner's fault1.
Breed rules. Agriculture and Markets Law § 107(5) lets municipalities, including New York City, adopt stricter dangerous-dog programs but forbids any program that regulates dogs in a manner specific as to breed9.
