A dog bite can happen in seconds — a neighbor’s yard, a city sidewalk, a friend’s living room — and the physical and emotional aftermath can be serious. If you’ve been bitten by a dog in New York, one of the first legal questions you’ll face is whether the owner can be held responsible. The answer depends on a legal framework that has evolved significantly, most recently with a landmark court decision in April 2025.
New York does not follow a single, simple rule. Instead, the state blends the traditional one bite rule with strict liability principles and, now, a newly recognized negligence standard. Understanding how each piece fits together can help you make informed decisions about your next steps.
Key Insight: In April 2025, New York’s highest court issued the Flanders v. Goodfellow decision, fundamentally expanding dog bite victims’ rights by allowing negligence claims even when a dog has no prior history of aggression.
Does New York Follow the One Bite Rule
Like many states, New York uses a version of the so-called “one-bite rule” to decide when a dog owner is strictly liable. However, instead of adhering to the typical one-bite rule, New York employs a complex combination of statutory and case law, distinguishing it from other states.
New York uses a mix of the one-bite rule and strict liability. With these mixed rules, a dog owner will be responsible for a bite victim’s losses based on whether or not they knew that their dog was dangerous. This means the outcome of your case can differ substantially depending on the dog’s history and what the owner knew — or should have known — before the attack.
While approximately 36 states impose automatic liability for dog bites regardless of prior knowledge, New York’s one-bite rule places additional burdens on victims. That said, the legal landscape shifted in a meaningful way in 2025. In April 2025, New York’s highest court recognized the unfairness of the prior approach and decided that dog-attack victims should be allowed to file negligence lawsuits.

How the One Bite Rule Works in New York
Contrary to popular belief, the term “one-bite rule” does not mean that every dog literally gets one free bite before liability attaches. Instead, it means that the owner must have had some notice that the dog posed a danger, which can come from a variety of aggressive behaviors beyond just a prior bite.
Under New York’s framework, the level of compensation you can recover depends on what the owner knew:
- Under these laws, a dog owner is strictly liable for all losses that a dog bite victim suffers if the dog owner knew or should have known of the dog’s vicious propensities.
- Dog owners are also strictly liable for all medical costs if their dog causes physical injury or death to another person even if the dog has never bitten or attacked someone before.
In practical terms, this creates two tiers of recovery:
- Full damages (including pain and suffering): If the dog has previously bitten or attacked a human, a dog owner will be liable for all losses, including property damage, medical bills, pain and suffering, and related losses.
- Medical costs only: If the dog has not previously bitten or attacked anyone, a dog owner will be liable for all medical costs associated with any physical injury that their dog causes.
The 2025 Flanders v. Goodfellow ruling added a third path. Now, individuals injured by a dog can pursue negligence claims if the owner failed to take reasonable care — even if it was the dog’s first time biting someone. This means that even if you cannot establish prior vicious propensity, you may still recover full damages by showing the owner acted carelessly.
Important Note: The governing statute for dog bites in New York is Agriculture and Markets Law § 123. Under this statute, if a plaintiff can prove that the dog was “dangerous” as per the law, the owner is strictly liable for any medical expenses that the dog bite caused.
What Victims Must Prove Under the One Bite Rule in New York
If you are pursuing a claim under the one-bite rule — seeking full damages including pain and suffering — the burden of proof falls on you. Under New York’s traditional one-bite rule, a dog owner can be held strictly liable for all damages, including pain and suffering, lost wages, and non-economic losses, if the victim proves that the dog had “vicious propensities” and that the owner knew or should have known about those propensities.
You will generally need to establish three things:
- The dog had vicious propensities. “Vicious propensities” is broadly defined under New York law to include any behavior that might endanger the safety of persons or property, even if the dog is not violent or ferocious.
- The owner had knowledge of those propensities. The crux of the one-bite rule hinges on the owner’s awareness of their dog’s potential for violence.
- The injury resulted from those propensities. An owner is strictly liable for all of a victim’s damages if they knew about their animal’s vicious propensity, and the damage or injury was caused by that vicious propensity.
If you cannot meet this standard but the owner acted carelessly, a victim can recover all of their damages — including compensation for their pain and suffering — by showing that an owner was careless in how they handled or controlled their dog, and this carelessness allowed the dog to injure the victim.
For comparison, see how neighboring states handle the burden of proof differently in our guides to Pennsylvania dog bite laws and Virginia dog bite laws.
What Counts as Prior Knowledge in New York
One of the most important — and often misunderstood — aspects of New York’s one-bite rule is what actually qualifies as evidence of prior knowledge. A previous bite is the clearest form of notice, but courts look well beyond that.
The state’s highest court has ruled that a jury is entitled to consider any evidence of a dangerous propensity, and that a prior bite is only one such type of evidence. Courts have accepted a wide range of behaviors as evidence that an owner knew or should have known their dog was dangerous:
- If the dog often jumps aggressively on people; if the dog has received training to fight; if the dog displayed previously vicious behavior; if there have been prior complaints against the dog; or if the dog has previously bitten or attacked someone.
- A pet owner will likely be held responsible for damages caused by an animal who has been trained to attack, because the owner is fully aware that their dog is dangerous and capable of violence.
- Prior frightening or vicious behavior can include situations in which a dog chases others to the point where they are frightened, or barks viciously from behind a fence as though it is willing to attack.
Physical signs on the owner’s property can also serve as evidence. Physical examples of the owner’s prior knowledge include “Beware of Dog” signs and fitting the dog with a muzzle while walking in public.
Pro Tip: The first step that a dog bite attorney will take will be to contact the dog owner’s neighbors and others who live within a small radius of the dog’s home. These attempts at contact are helpful, as neighbors may report having been chased by the dog or feeling too afraid to let their children near the owner’s yard.
Attorneys can also use public records to build a case. Through requests under the Freedom of Information Act, attorneys can ask for information from various governmental entities about any records of a previous attack or propensity from that dog.
Exceptions and Defenses to the One Bite Rule in New York
Even when you can establish prior knowledge and vicious propensity, a dog owner may still raise defenses that reduce or eliminate their liability. Understanding these defenses helps you anticipate what you may face.
| Defense | How It Works in New York | Impact on Your Claim |
|---|---|---|
| Provocation | Owner argues the victim provoked the attack through teasing, hitting, or threatening the dog | Can reduce or eliminate owner liability |
| Trespassing | If the plaintiff was on the owner’s property without their consent, even if the dog has bitten before, the owner may not be held liable | May bar recovery entirely |
| No Prior Knowledge | If the owner has no knowledge whatsoever that the dog has bitten before, they are not liable under the one-bite rule | Limits recovery to medical costs only |
| Justified Defense | Any danger the dog causes if it bites while defending its owner or offspring is deemed justified | May excuse the dog’s behavior entirely |
| Pain or Suffering Reaction | The law excuses any injuries caused by a dog that was reacting to pain or suffering | May reduce or eliminate liability |
Keep in mind that, even under strict liability, an owner is only liable for unjustified attacks. The law can excuse a dog’s behavior if it’s been provoked or is acting to defend itself, its owner, or others.
Children occupy a special position in these cases. If the victim is a child, the property owner is responsible whether there was a warning sign or not. Courts tend to hold owners to a higher standard when young children are involved, recognizing that children may not fully understand how to interact safely with animals.
Dog Owner Liability Beyond the One Bite Rule in New York
New York’s liability framework extends well beyond the traditional one-bite rule. Even if you cannot establish prior vicious propensity, several other legal theories may support your claim.
Negligence (Post-2025 Flanders Rule)
Before April 17, 2025, New York was among a minority of states that required dog bite victims to prove the owner knew their dog had vicious propensities. What made New York particularly restrictive was its 2006 Bard v. Jahnke decision that barred negligence claims entirely for domestic animal injuries, meaning victims often could not recover damages even when owners were clearly negligent. The April 17, 2025 Flanders v. Goodfellow decision overturned that restriction, allowing victims to pursue negligence claims and aligning New York more closely with most other states.
Evidence such as violations of leash laws, broken fences, prior complaints to animal control, and the owner’s failure to supervise the dog can all support a negligence claim.
Dangerous Dog Designation
When a dog has been formally adjudicated as “dangerous” under Agriculture and Markets Law § 123, owners face automatic strict liability for all medical costs, regardless of precautions taken. The definition of a dangerous dog under New York law is specific. New York law defines a dangerous dog as a dog that attacks a person, companion animal, or farm animal without justification and causes physical injury or death; or behaves in a way that a reasonable person would believe poses a serious and unjustified imminent threat of serious physical injury or death to one or more people, companion animals, farm animals, or domestic animals.
Landlord Liability
If you were bitten in an apartment building or rental property, the landlord may also bear responsibility. The dog bite liability is attached to the landlord if they knew that a tenant’s dog was dangerous but failed to take action. You would need to show that the landlord had actual or constructive knowledge of the dog’s dangerous nature and failed to address it.
Criminal Penalties
Beyond civil liability, owners of dangerous dogs can face criminal consequences. If a dog previously determined to be dangerous causes serious physical injury, the owner faces misdemeanor charges punishable by fines up to $1,000, imprisonment up to 90 days, or both. In the most serious cases, if an owner’s “dangerous” dog kills someone, the owner is strictly liable and could face up to one year in jail, even if they took precautions to protect the public from the dog.

What to Do After a Dog Bite in New York
The steps you take in the hours and days following a dog bite directly affect both your health and your legal options. Acting quickly and methodically gives you the strongest possible foundation for a claim.
1. Seek Medical Care Immediately
After a dog bite incident in New York, the first and most important action is to seek medical care. Dog bites can cause deep wounds, and even if the injury appears minor, it may carry a risk of infection or complications. Some bites can introduce bacteria into the bloodstream, leading to serious infections like tetanus or rabies. Medical records created at this stage become critical evidence later.
2. Document Everything at the Scene
Take photos of your injuries, the location, and the dog if possible. Gather witness names and contact information. It is also beneficial to write down everything you remember about the incident, including how the attack occurred, the behavior of the dog before the bite, and any interactions with the owner.
3. Get the Owner’s Information
If the dog owner is present at the scene, ask for their name, contact information, and details about the dog, including vaccination records. If the owner is not present or the dog is a stray, try to gather information from any witnesses who may have seen the attack or know where the dog lives.
4. Report the Bite to Authorities
Reporting is both a legal requirement and a practical necessity. New York City Health Code § 11.03 requires that all animal bites be reported within 24 hours of the event. This is not optional; it is a legal requirement that applies to every bite incident, regardless of severity. If the attack occurred outside New York City, report the bite to your county health department immediately. Each county maintains its own animal control and public health reporting systems.
Important Note: Reporting enables NYC Veterinary Public Health Services to coordinate a 10-day observation period for the biting dog to determine whether it is healthy and rabies-free, potentially sparing the victim from unnecessary rabies post-exposure prophylaxis.
5. Investigate the Dog’s History
Investigate prior incidents. Contact local animal control to determine if the dog has previous complaints, bite reports, or a dangerous dog designation. This information proves crucial for establishing strict liability under both the dangerous dog statute and the one-bite rule.
6. Preserve Physical Evidence
Preserve physical evidence. Keep damaged clothing, torn personal items, and any other physical evidence in a safe place. These items can demonstrate the attack’s severity and corroborate your account.
7. Be Careful with Insurance Companies
Refrain from speaking with insurance companies, as they may attempt to minimize your claim or pressure you into a low settlement. Insurance companies work hard to minimize legitimate personal injury claims — including those related to dog bites. They will often use a variety of tactics to try to reduce the amount that they have to pay out or will attempt to deny the claim outright.
8. Know Your Statute of Limitations
In New York, the statute of limitations for personal injury lawsuits is three years. That means the victim of a dog attack has three years from the date of the incident to file a lawsuit against the owner or anyone else who might be legally responsible. However, dog bite victims in New York face a three-year statute of limitations to file a personal injury lawsuit, and claims involving public entities may have notice requirements as short as 90 days. Missing these deadlines can permanently destroy even the strongest case.
9. Consult an Attorney
New York now offers victims two parallel paths to recovery: strict liability based on the owner’s knowledge of dangerous propensities — the traditional “one-bite rule” — and negligence based on the owner’s failure to exercise reasonable care, introduced by the 2025 Flanders decision. An experienced dog bite attorney can evaluate which path best fits your situation and help you build the strongest possible case.

New York’s dog bite framework rewards victims who act quickly, document thoroughly, and understand the legal tools available to them. The 2025 shift in the law means you have more options than ever before — but navigating them effectively still requires knowing where you stand.
