New York Dog Bite Law

New York is a “mixed” state, meaning that it has a dog bite statute that mixes the one-bite rule with a limited degree of strict liability. The statute makes the owner or keeper of a previously adjudicated “dangerous dog” strictly liable only for the victim’s medical and veterinary costs. For other damages, New York requires a victim to prove that the dog had the dangerous tendency to bite people, and that the dog owner knew it. New York does not permit victims to recover compensation on the ground of negligence, at least in most circumstances where the defendant is the owner of the attacking dog. 

Strict liability for medical costs if dog is “dangerous”

Agriculture & Markets Law, Section 121, makes the “owner or lawful custodian” of a “dangerous dog” “strictly liable” for medical costs resulting from “injury” caused by such dog to a person, “companion animal,” farm animal or “domestic animal.” Section 121 contains a number of definitions:

  • The “owner” is a person who harbors or keeps the dog. (Sec. 108, subd. 15.)
  • A “dangerous dog” is one that “without justification” either (a) attacks and injures or kills a person, “companion animal,” farm animal or “domestic animal” or (b) “behaves in a manner which a reasonable person would believe poses a serious and unjustified imminent threat of serious physical injury or death” to one or more of the foregoing. (Sec. 108, subd. 24(a).) There is an exception for dogs assisting the police. (Sec. 108, subd. 24(b).) The conduct of the victim, either on the day of the attack or at a much earlier time, also can exempt a dog from “dangerous” status. (Sec. 121, subd. 4.)

In addition to liability for medical costs, the owner of a dangerous dog may be required to pay a fine if his negligence results in a dog bite to a person, service dog, guide dog or hearing dog. The amount of the fine depends on whether the injury was to a person or animal, the seriousness of the injury, and whether the dog previously was adjudicated to be a dangerous dog. Agriculture & Markets Law, Section 121, subdivisions 6, 7 and 8.)

Criminal penalties

If a dog owner negligently permits his dog to bite a person, the dog previously was declared to be dangerous, and the injury is a “serious injury,” the dog owner can be convicted of a misdemeanor ($1000 file and 90 days in jail). Agriculture & Markets Law, Section 121, subdivision 8.) A “serious injury” is one that causes death or presents the risk of death, or causes “serious or protracted” disfigurement, “protracted impairment of health or protracted loss or impairment of the function of any bodily organ.” Agriculture & Markets Law, Section 108, subdivision 29.)

If a dog previously declared dangerous escapes or otherwise gets to a person and kills him, the owner can be convicted of a class A misdemeanor, in addition to other penalties and civil liability. Agriculture & Markets Law, Section 121, subdivision 9.)

New York is a “one bite state ” for damages other than medical costs

New York courts have long recognized a cause of action that imposes strict liability on the owner for injuries inflicted by his dog if the victim can establish that the dog is vicious and that the owner knew or should have known about such vicious propensities. The state’s highest court ruled “that the owner of a domestic animal who either knows or should have known of that animal’s vicious propensities will be held liable for the harm the animal causes as a result of those propensities. Vicious propensities include the propensity to do any act that might endanger the safety of the persons and property of others in a given situation.” Bard v. Jahnke, 6 NY3d 592 (N.Y. 2006), citation omitted.

Evidence of vicious propensity

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:

[W]hile knowledge of vicious propensities “may of course be established by proof of prior acts of a similar kind of which the owner had notice,” a triable issue of fact as to whether the owner knew or should have known that its animal harbored vicious propensities may be raised by proof of something less (Collier, 1 NY3d at 446). In Collier, a case in which a dog bit a child, we gave the example of evidence that a dog had, for example, “been known to growl, snap or bare its teeth,” or that “the owner chose to restrain the dog, and the manner in which the dog was restrained” (id. at 447). “In addition, an animal that behaves in a manner that would not necessarily be considered dangerous or ferocious, but nevertheless reflects a proclivity to act in a way that puts others at risk of harm, can be found to have vicious propensities albeit only when such proclivity results in the injury giving rise to the lawsuit” (id.). [Bard v. Jahnke, 6 NY3d 592 (N.Y. 2006).]

Presence of “Beware of Dog” signs standing alone are not enough to imply that dog owner knew of his dog’s vicious propensities.  Altmann vs Emigrant Savings Bank, 249 AD2d 67, 68 (First Dept, 1998); Frantz vs McGonagle, 242 AD2d 888 (Fourth Dept, 1997); Arcara vs Whytas, 219 AD2d 871, 872 (Fourth Dept, 1995).

A defendant who establishes by undisputed proof that his dog had never bitten anyone before and had never bared its teeth or growled at anyone before is entitled to summary judgment.  Arcara vs Whytas, 219 AD2d 871, 872 (Fourth Dept, 1995).

The fact that a dog was chained and strained on its chain and barked when people approached was held insufficient to create an inference that the dog was vicious.  Gill vs Welch, 136 AD2d 940 (Fourth Dept, 1988).

In determining whether an animal has vicious propensities, a jury may consider the nature and the result of the attack on the victim. Lynch vs Nacewicz, 126 AD2d 708, 709 (Second Dept, 1987).

Evidence of the severity of injuries by prior victims of same dog is admissible as probative of the dog’s vicious propensities and the owner’s knowledge of same. Lynch vs Nacewicz, 126 AD2d 708, 709 (Second Dept, 1987). 

Negligence not recognized as ground

New York cases refer to negligence as a ground against parties other than the owner of the attacking dog, but do not permit recovery for general or common-law negligence from the owner of the attacking dog unless he or she knew or should have known that the dog in question had a vicious or dangerous temperament — in other words, in cases against the owner of the dog, the victim has to prove scienter. Bard v. Jahnke, 6 NY3d 592 (N.Y. 2006), citing Collier v Zambito, 1 NY3d 444 (2004). The Bard court stated emphatically, “when harm is caused by a domestic animal, its owner’s liability is determined solely by application of the rule articulated in Collier.” Id. For the definition of “scienter,” see The One Bite Rule at For a great summary of the relevant New York cases, see Richards, Karen M., Court of Appeals Takes the Bull by Its Horns: Liability for Roaming Cattle and Other Domestic Animals (2014). 

New York courts, including the Court of Appeals (the highest court of the state), have been edging away from the Bard rule. As stated in the dissent in a recent Court of Appeals case, NY courts always have applied negligence principles in domestic animal liability cases until they wrongly decided Bard and thuse deviated from not only American law but also the English common law from whence NY inherited the one bite rule. For more, see NY Courts Edge Closer to Fairness for Dog Bite Victims by Attorney Kenneth M. Phillips. 

Negligence per se

New York has a unique restriction on the doctrine of negligence per se. If a person violates a state law, the violation constitutes negligence per se, and equals negligence without more proof. If a person violates a city or county law, however, the violation constitutes evidence of negligence but not negligence per se. Kevin Elliott v. City of New York, 95 N.Y. 2d 730; 747 N.W.2d 760 (2001) (“As a rule, violation of a State statute that imposes a specific duty constitutes negligence per se, or may even create absolute liability. [Citations omitted.] By contrast, violation of a municipal ordinance constitutes only evidence of negligence.”)

The Court of Appeals has specifically held that there is no cause of action for negligence when a dog bites a person while in violation of a leash law. (Petrone v. Fernandez, 12 N.Y.3d 546, 550, 910 N.E.2d 993, 996 (2009).)

Landlord liability

To hold a landlord liable for a bite injury caused by a tenant’s dog, the victim must prove that at the time of the initial leasing the landlord had actual knowledge of (1) the presence of the dog and (2) the dog’s vicious propensity to bite humans. Strunk v. Zoltanski, 62 N.Y.2d 572, 468 N.E.2d 13, 479 N.Y.S.2d 175 (1984). Landlords can even be held liable for off premises attacks under the general common-law rule where the landlord has the right to remove the animal by evicting the tenant. Strunk v. Zoltanski, supra, 62 N.Y.2d at p. 576; see also Cronin v. Chrosniak, 145 App. Div. 2d 905, 906–907, 536 N.Y.S.2d 287 (1988).

Summary Judgment

If a defendant moves for summary judgment and introduces admissible evidence that indicates that defendant had no knowledge of the dog’s vicious propensities, plaintiff must submit rebuttal evidence or risk having his complaint dismissed.  Luts vs Weeks, ___AD2d___(Second Dept, 1/31/2000); Althoff vs Lefebvre, 240 AD2d 604 (Second Dept, 1997); Smith vs Farner, 229 AD2d 1017, 1018 (Fourth Dept, 1996); Arcara vs Whytas, 219 AD2d 871, 872 (Fourth Dept, 1995); Fox vs Martin, 174 AD2d 875, 876 (Third Dept, 1991); Gill vs Welch, 136 AD2d 940 (Fourth Dept, 1988). 

If a defendant fails to submit admissible evidence his summary judgment motion must be denied.  Pringle vs New York City Housing Authority, ___AD2d____; 689 NYS2d 181, 182(Second Dept, 1999).

If there is conflicting evidence regarding the dog’s vicious propensities, that issue must be given to the jury to decide.  Frantz vs McGonagle, 242 AD2d 888 (Fourth Dept, 1997).

Proof that dog was bred to be aggressive and was high strung and territorial not enough to raise issue of fact regarding the dog’s vicious propensities or owner’s knowledge of same.  Wilson vs Whiteman, 237 AD2d 814, 815 (Third Dept, 1997).


Out-of-pocket, lost wages and punitive damages were all recoverable in Nardi vs Gonzalez, 165 Misc2d 336, 339 (1995)(note that although this case involved a dog injuring another dog, the court stated that such damages could be recoverable in an attack on a human).

Damages of $310,000.00 were held excessive where evidence indicated that the victim was able to perform most of her household duties and work full time, and was coping with phobia of dogs by seeking counseling.  Fontecchio vs Esposito, 108 AD2d 780, 781-782 (Second Dept, 1985).

An attack on another dog or companion animal

An attack on another dog or companion animal can result in serious consequences for the dog owner or keeper as well as the attacking dog itself. A judge or magistrate can determine that the dog is dangerous and impose penalies on the owner and conditions of confinement of the dog. The dog even can be euthanized if it previously was declared dangerous and this time it inflicted serious injuries or death on another dog. For more information, see Agriculture & Markets Law, Section 121.

Change the dog bite law of New York

New York needs to move into the 20th Century (it was in that century that most of the strict liability dog bite laws were enacted). Although it is thought of as a liberal state, New York’s dog bite laws are almost exactly the same ones that were created in the 17th century by British judges for the quaint English countryside. The highest court of New York has even ruled in Bard that there is no such thing as dog owner negligence. Reliance on the one bite rule is completely wrong, in modern New York or any other American state, because when the one bite rule was established there were no pit bulls, the practice of dog fighting had not been invented, there was no insurance industry to spread the risks, and there was no USA with its focus on fairness and human rights. All those things have changed, and that is why dogs have lost their right to bite in most states.

New York needs a strict liability law like that of nearby New Hampshire. The state of New Hampshire has a law pertaining to canine-inflicted injuries that covers any cause of damage by a dog, and applies to injuries to not only humans but also any form of property, including another dog or cat. (The text of the statute is set forth at the New Hampshire section of Such a law is worth fighting for. (For more, see Help New York Improve Its Dog Bite Law.)

In 2015, there began a legislative attempt to correct the Bard decision. State Senator Robert J. Ortt (R-Dist. 62) asked Attorney Kenneth M. Phillips to propose revisions of the New York statutes involving dog bite liability, and Mr. Phillips responded with a draft of a bill that would have brought New York law in alignment with two-thirds of American states, including both “red states” and “blue states.” Since then, however, Sen. Ortt’s bill has been pending in one committee after another, with no decision in sight.
