New York dog bite law changed significantly in 2025 after the state's highest court overruled nearly two decades of precedent, allowing bite victims to pursue negligence claims even when a dog has no prior history of aggression.
Before this ruling, dog owners in New York often escaped full liability if their pet had never bitten before, a concept widely known as the "one bite rule." That shield is now gone.
Dog bites are not rare incidents. The CDC estimates approximately 4.7 million dog bites occur annually in the United States, and a published study using New York City emergency department data found more than 6,000 animal bite patient visits per year in NYC alone, with dog bites accounting for over 70% of those visits.
If you or someone close to you was bitten, understanding how New York law works right now is the first step toward knowing whether you have a case.

What Was the "One Bite Rule" and Did New York Ever Follow It?
New York never had a pure "one bite rule" written into statute. But for years, the practical result was similar. Under a 2006 Court of Appeals decision called Bard v. Jahnke, plaintiffs injured by domestic animals were barred from relying on ordinary negligence.
They were limited to strict liability claims based on proof that the owner knew or should have known about the dog's "vicious propensities."
If they could not prove that prior knowledge, the owner often escaped liability for pain, suffering, and other non-economic damages, even if the owner had been obviously careless.
Vicious propensities is a broader concept than it sounds. A dog does not need to have bitten before. Courts have found vicious propensities based on:
- Prior attacks on people or other animals
- Repeated growling, snapping, or bearing of teeth
- Being kept as a guard dog
- Needing consistent restraint, muzzling, or heavy control measures
Still, the requirement to prove that the owner knew about any of this created a real barrier for first-bite victims. That is where the shorthand "one free bite" came from. It was not technically the law, but it was often the outcome.
What Did New York's Dangerous Dog Statute Actually Say?
New York Agriculture and Markets Law § 123, titled "Dangerous Dogs," has long been the state's primary dog bite statute. It creates a specific legal process for having a dog declared "dangerous" and imposes statutory strict liability for certain costs once that designation is made.
Under § 123, a dog can be found dangerous if it:
- Attacks a person, companion animal, farm animal, or other pet without justification and causes physical injury or death, or
- Behaves in a manner that a reasonable person would believe poses a serious, unjustified, imminent threat of serious physical injury or death
Once a dog is adjudicated dangerous under this statute, the owner is strictly liable for the victim's medical expenses from the attack.
That means you do not have to prove negligence to recover medical costs, only that the dog was designated dangerous and caused your injury.
The statute also gives courts authority to order secure confinement, muzzling, mandatory training, or in extreme cases involving serious injury or death, humane euthanasia if the dog is deemed a continuing threat.
There are statutory defenses, however. A dog is generally not considered dangerous if it was protecting its owner or property from someone committing a crime, responding to pain or injury, or protecting itself or its household from an imminent threat.
How Did Flanders v. Goodfellow Change Everything?
In April 2025, the New York Court of Appeals issued its ruling in Flanders v. Goodfellow, 2025 NY Slip Op 02261, and in doing so, explicitly overruled Bard v. Jahnke.
The facts were straightforward. A postal worker delivering a package was bitten by the defendant's dog and sued on both strict liability and negligence grounds. Lower courts, following Bard, dismissed the negligence claim and focused only on whether the owner knew about vicious propensities.
The Court of Appeals reversed course. The court held that plaintiffs injured by domestic animals may now pursue common law negligence claims in addition to strict liability claims.
The court clarified that New York law never actually prohibited negligence actions in dog bite cases. Bard had improperly added that restriction, and it was time to correct the record.
What this means in practice is that a dog bite victim in New York now has two independent legal paths:
| Theory | What You Must Prove | Damages Available |
| Strict liability (vicious propensities) | Owner knew or should have known the dog had dangerous tendencies | Full compensatory damages |
| Negligence (post-Flanders) | Owner failed to exercise reasonable care, even without prior incidents | Full compensatory damages |
| Statutory (§ 123) | Dog was adjudicated "dangerous" and caused the injury | Medical expenses only |
The negligence path is particularly significant for first-bite cases. A dog owner who violated a local leash law, allowed a dog to roam unsecured around children, or failed to restrain an animal in a situation where a reasonable person would have can now be held liable even if the dog never showed aggression before.
As legal commentators have noted after Flanders: it is no longer the rule in New York State that every dog gets one free bite.
What Does a Victim Need to Prove After Flanders?
The answer depends on which theory your attorney pursues, and a competent personal injury attorney will likely pursue all viable theories simultaneously.
For a strict liability claim, the victim must demonstrate that the owner had actual or constructive knowledge of the dog's vicious propensities. Evidence can include prior bite reports, complaints from neighbors, veterinary notes about aggression, or the manner in which the owner kept and handled the dog.
For a negligence claim, the victim must show that the owner failed to act with reasonable care and that this failure caused the injury. Examples of negligent conduct include violating a municipal leash ordinance, knowingly allowing a dog to interact with strangers in a way that creates foreseeable risk, or failing to properly secure a gate or enclosure. Critically, there is no requirement under this theory to show the dog had been aggressive before.
For the statutory medical expense claim under § 123, the victim must show the dog was adjudicated dangerous through the local court process and that the attack caused the specific medical costs being claimed.
In any of these cases, New York's pure comparative negligence rule under CPLR § 1411 still applies. If a victim is found partially at fault, for example by provoking the animal or ignoring an obvious warning, the damages award is reduced proportionally by their percentage of fault. You can still recover even if you are found to be partially responsible.
What Defenses Can a Dog Owner Raise?
Owners and their insurers routinely challenge dog bite claims, and the defenses available under New York law are worth understanding.
Under Agriculture and Markets Law § 123, the statutory defenses include provocation, trespassing, and justification. These defenses can apply to both the statutory claim and the broader civil suit.
In negligence cases, owners will typically contest whether their conduct was actually unreasonable given the circumstances, challenge causation, or argue that the victim assumed the risk of interacting with the animal.
It is worth noting that New York City has additional animal bite reporting requirements under the NYC Health Code dog bite guidelines, including mandatory reporting within 24 hours of a bite. This creates a paper trail that can work in a victim's favor, or if not followed by the owner, become evidence of negligence.
What Should You Do After a Dog Bite in New York?
The steps you take immediately after a dog bite can affect both your medical outcome and your legal case.
- Wash the wound thoroughly with soap and water and seek medical care promptly. Dog bites carry a significant infection risk, and a treating physician's records will document the nature and severity of the injury.
- Identify the dog and its owner. Obtain contact information, vaccination records if possible, and any information about prior incidents.
- Report the bite. In New York City, dog bites must be reported within 24 hours to the NYC Department of Health Animal Bite Unit via 311 so the department can evaluate rabies risk. Outside NYC, reporting requirements vary by municipality.
- Photograph the injuries, the scene, and any conditions that may have contributed to the attack such as an unlatched gate or missing leash.
- Do not give a recorded statement to an insurance company without speaking with an attorney first. Insurance adjusters represent the owner's interests, not yours.
The statute of limitations for a personal injury lawsuit in New York is generally 3 years from the date of the attack under CPLR § 214. If the bite occurred on government property or involved a municipality in some way, the deadline to file a Notice of Claim may be as short as 90 days from the incident.
Missing that window can permanently bar your claim, even if the general statute of limitations has not expired.

Frequently Asked Questions About NY Dog Bite Law
Does New York still have a one bite rule?
No. As of 2025, New York does not give every dog one free bite. After Flanders v. Goodfellow, dog bite victims can now pursue a negligence claim even if the dog had no known prior history of aggression. The strict liability path based on vicious propensities still exists alongside the negligence route, but neither requires a prior bite to succeed.
How much can I recover after a dog bite in New York?
The amount depends on the severity of your injuries, lost income, medical expenses, and the degree of pain and suffering you experienced. There is no statutory cap on dog bite damages in New York. Cases involving serious injuries such as deep lacerations, nerve damage, facial scarring, infections requiring surgery, or psychological trauma tend to result in significantly higher recoveries. No attorney can guarantee a specific outcome, and prior results do not guarantee similar outcomes in your case.
Can I sue if I was bitten by a neighbor's dog?
Yes. The relationship between you and the dog's owner has no bearing on whether a legal claim exists. What matters is the circumstances of the attack: was the owner negligent, did the owner know about prior dangerous behavior, or was the dog designated dangerous under Agriculture and Markets Law § 123. Homeowners' and renters' insurance policies frequently cover dog bite liability, which means there is often an insurer involved even in neighbor-on-neighbor claims.
What if I was partially at fault for the dog bite?
Under New York's pure comparative negligence rule under CPLR § 1411, your damages are reduced by your percentage of fault, but you are not barred from recovering. If a jury finds your total damages to be $100,000 but determines you were 25% at fault, you would receive $75,000. This is a more plaintiff-friendly standard than most states, many of which bar recovery entirely once a plaintiff reaches 50% or 51% fault.
Does it matter if the dog had no leash on?
Yes, it can. Violating a local leash law is relevant evidence in a negligence claim. It demonstrates that the owner failed to exercise the reasonable care expected of a dog owner. Many municipalities in New York have leash ordinances, and a violation can support the argument that the owner created a foreseeable risk of injury.
How long do I have to file a lawsuit after a dog bite in New York?
The general statute of limitations for personal injury claims in New York is 3 years from the date of the incident under CPLR § 214. However, if the dog was owned or controlled by a government entity or the injury occurred on government property, you may need to file a Notice of Claim within 90 days. Cases involving minors are treated differently. Under CPLR § 208, the statute of limitations is tolled until the child's 18th birthday, giving them until age 21 to file.
Should I report the dog bite?
Yes. In New York City, reporting is legally required within 24 hours under the city's Health Code. Reporting creates an official record and initiates the NYC Health Department's animal bite and rabies risk evaluation process. Outside NYC, reporting is encouraged and may trigger a dangerous dog hearing that could result in the dog being officially designated "dangerous," which creates statutory strict liability for your medical expenses under Agriculture and Markets Law § 123.
What if the dog that bit me has bitten someone before?
Prior bite history is strong evidence of vicious propensities, which supports a strict liability claim against the owner. Prior incidents may also appear in municipal records, animal control reports, or prior civil filings. If you know or suspect the dog has bitten before, tell your attorney. That history can be decisive in establishing what the owner knew and when.
Summing It Up
New York dog bite law has always been more layered than the "one bite rule" label suggested. Agriculture and Markets Law § 123 created a statutory framework for dangerous dog designations and limited strict liability for medical costs.
The common law added strict liability based on vicious propensities. What was missing, until Flanders v. Goodfellow in 2025, was a clear right to sue in negligence.
That gap is now closed. Dog owners in New York are held to a standard of reasonable care, and a first bite can generate full liability if the owner's negligence contributed to the attack. For victims, that means more paths to recovery. For owners, it means that a lack of prior incidents is no longer a reliable defense.
