New Jersey Dangerous Dog Law

What happens right after the bite?

Two separate systems start. The first is public health. A doctor who treats the bite must report it to the local health department within 12 hours, and if no doctor is involved the adult who was bitten, or the parent of a bitten child, must report it¹². The health department then serves a notice (form VPH-11) ordering the owner to confine the dog for at least ten days, at the owner's expense, either at home or at a shelter or veterinary hospital named in the notice^12,13. An inspector checks the dog at the start, and the dog is released only when the department signs a certificate of release^12,13. If the dog shows signs of rabies, it is examined by a veterinarian and may be euthanized and tested, and the owner must first be told why testing is needed^13,14.

The second system is the Vicious and Potentially Dangerous Dog Act of 1989, which applies statewide and replaces local dangerous-dog ordinances¹⁰. Most bites never reach it. It starts when the animal control officer has reasonable cause to believe the dog attacked a person and caused death or serious bodily injury, or caused bodily injury in an unprovoked attack and poses a serious threat to people or domestic animals. In those cases the officer must seize and impound the dog until the case is decided; with the health officer's approval it can be held at a facility the owner agrees to¹⁰.

How is a dog declared vicious or potentially dangerous?

The officer notifies the municipal court and the health officer immediately, and must notify the owner by certified mail within three working days of identifying them. The owner then has seven days to return a signed statement either asking for a hearing or giving up the dog. An owner who does not answer, or refuses the certified letter, risks having the dog humanely destroyed¹⁰. The municipality and the owner may also settle the case on agreed terms at any point¹⁰.

At the hearing, the municipal court applies a clear-and-convincing-evidence standard, higher than in an ordinary civil case^10,11:

• Vicious dog: the dog killed a person or caused serious bodily injury. A provoked dog cannot be declared vicious, and the municipality must prove the dog was not provoked.
• Potentially dangerous dog: the dog caused bodily injury in an unprovoked attack and poses a serious threat of serious injury or death to a person, or it seriously injured or killed another domestic animal and poses a serious threat to people or to other animals.

Since a 2019 amendment, the Act lists situations that cannot support a potentially dangerous finding: a provoked bite, a fight the other animal started, a bite to someone committing a crime against the owner or trespassing on the owner's property, a bite to someone abusing or threatening the dog or its puppies, and a bite to someone breaking up a dog fight¹¹. Dogs used for law enforcement are outside the Act entirely¹⁰.

Either the owner or the animal control officer can appeal the municipal court's decision to the Superior Court, Law Division, which hears the case from the beginning under the court rules for appeals from courts of limited jurisdiction¹⁰.

What must the owner of a potentially dangerous dog do?

The court issues an order and compliance schedule, with no more than 60 days to comply. The dog stays impounded until the owner gets a special municipal license, registration number and red identification tag, and the registration number must be tattooed on the dog. The owner builds a locked enclosure with solid sides, top and bottom inside a six-foot fence, posts a warning sign, and keeps the dog muzzled and on a short tether under direct supervision whenever it is out of the enclosure¹⁰. The court may also require liability insurance in an amount it chooses; there is no fixed statewide minimum¹⁰. The animal control officer inspects the property at least monthly, and the annual license fee runs from $150 to $700¹⁰. The owner must report the dog being loose or attacking, and give 24 hours' notice of its death, sale or donation, telling any buyer about the designation¹⁰.

When can the dog be euthanized?

For a vicious dog, the court may order euthanasia or restrictions at least as strict as those for a potentially dangerous dog, but no dog may be euthanized while an appeal is pending¹¹. A potentially dangerous dog can be seized again and destroyed by court order if the owner ignores the Act or the order, and the owner faces fines of up to $1,000 for each day of violation¹⁰. Once appeals end, the owner pays the costs of impoundment and destruction, and pays for impoundment outside the municipal pound whatever the outcome¹⁰. If the dog bit someone within ten days before euthanasia, its head goes to the state laboratory for rabies testing¹⁰.

What if the dog bites again?

A court that clears a dog keeps the power to hold a new hearing on its later conduct¹⁰. The owner of a dog already declared potentially dangerous must report it to the licensing authority, police and animal control officer if it attacks a person, and a new attack that kills or seriously injures someone meets the test for a vicious dog^10,11.

Are owners charged with crimes?

The Act's penalties are municipal-court fines, not criminal offenses. A 2025 Senate bill to create offenses for owners whose unrestrained dogs injure people stated that existing law does not explicitly impose criminal culpability on them¹⁵. Breed is irrelevant: the Act overrides any local law aimed at a specific breed¹⁰.

Rules for a declared dog in New Jersey

New Jersey rules in brief

Reporting. A physician who treats a bite must report it to the local health department within 12 hours; if no physician attends, the adult bitten, or the parent or guardian of a bitten child, must report within 12 hours (N.J.S.A. 26:4-79 to -81)¹². The Department of Health tells anyone bitten to notify the local health department where the animal is located¹⁴.

Euthanasia. A municipal court that finds by clear and convincing evidence that an unprovoked dog killed a person or caused serious bodily injury declares it vicious and may order it euthanized, though never while an appeal is pending; either side may appeal to the Superior Court, Law Division, which hears the case anew^10,11. A potentially dangerous dog whose owner breaks the court's order can also be seized and destroyed¹⁰.

Criminal penalties. No New Jersey statute makes a serious or fatal dog attack a crime in itself. The owner of a potentially dangerous dog who violates the Act or a court order faces fines of up to $1,000 per day¹⁰. A 2025 bill to create criminal offenses for owners whose unrestrained dogs injure people noted that existing law does not explicitly impose criminal culpability¹⁵.

Breed rules. The Act supersedes any municipal, county or local health board law on vicious or potentially dangerous dogs or "any specific breed of dog" that is inconsistent with it¹⁰.
