Can You Shoot a Dog on Your Property in New Hampshire? What the Law Actually Says
June 23, 2026
Few situations on a rural New Hampshire property feel more alarming than a strange dog charging at you, your children, or your livestock. When adrenaline takes over, the instinct to reach for a firearm can feel entirely justified. But whether that instinct is legally protected is a separate question — and the answer depends on very specific facts that New Hampshire law takes seriously.
New Hampshire does have a statute that permits civilians to kill a dog under defined circumstances, but the legal window is narrower than most people assume. Acting outside it can expose you to criminal charges, civil liability, and a permanent record. This article walks through exactly what the law says, where it draws the line, and what happens after a shooting occurs.

Is It Legal to Shoot a Dog on Your Property in New Hampshire?
The short answer is: sometimes, but only under narrow conditions. New Hampshire is one of the states that explicitly addresses civilian dog killings in its statutes. Under RSA 466:28, titled “Killing Dogs Legalized,” any person may kill a dog that suddenly assaults the person while such person is peaceably walking or riding without the enclosure of its owner or keeper, and any person may kill a dog that is found out of the enclosure or immediate care of its owner or keeper worrying, wounding, or killing sheep, lambs, fowl, or other domestic animals.
That statute creates two distinct justifications: a personal assault on you, or an active attack on your domestic animals. Neither justification is a blanket permission to shoot any dog that enters your land. The law is specific about what must be happening at the moment you act — and courts and police will scrutinize the facts closely after the fact.
New Hampshire also has a parallel provision aimed at law enforcement. Under RSA 466:36, any conservation officer, state police officer, dog constable, or any New Hampshire certified police officer may kill any dog found in the act of maiming or in close pursuit of deer, moose, caribou, sheep, cattle, swine, poultry, or any domestic animal. This authority belongs specifically to officers — it does not extend to private property owners acting on their own.
Key Insight: RSA 466:28 protects you only when the threat is active and ongoing. It is not a retroactive defense for shooting a dog because it caused harm yesterday or might cause harm tomorrow.
The Livestock and Pet Protection Exception in New Hampshire
For property owners who keep chickens, sheep, rabbits, goats, or other domestic animals, RSA 466:28 does offer meaningful protection — but the wording matters. The statute covers a dog that is found “worrying, wounding, or killing” livestock. All three of those words describe active, present-tense conduct.
“Worrying” in the legal sense means the dog is actively harassing or threatening the animals — chasing them, snapping at them, or causing them obvious distress. A dog that walked through your pasture an hour ago and left does not meet this standard. A dog that is currently circling your chicken coop and causing your birds to scatter in a frenzy likely does.
Real-world cases in New Hampshire illustrate how blurry this line can be. In one widely reported Hampstead case, a retired Manchester police officer was cleared of any wrongdoing by police after he used an AR-15 to shoot and kill a neighbor’s 6-year-old Brittany spaniel. He said he killed the dog because she wandered onto his property and frightened his two caged rabbits by barking at them and chasing around the outside of their cage. While the dog never got inside the cage, he told police he was concerned for the rabbits because they are fragile and susceptible to heart attacks.
Police cleared him under RSA 466:28, but the case sparked significant public debate and a legislative push to tighten the statute’s language. One lawmaker said she “didn’t want a law with interpretive language to be an excuse for killing a neighbor’s pet,” but the bill hit resistance from farmers who were afraid that any change would have a detrimental effect on their livestock. The statute’s language remains broad enough that outcomes can differ depending on local law enforcement interpretation.

What “Immediate Danger” Means Under New Hampshire Law
The personal assault prong of RSA 466:28 requires that the dog “suddenly assaults” you. That phrase carries specific legal weight. A sudden assault means the dog is actively attacking or charging you with no opportunity for retreat or de-escalation. It does not mean the dog is barking, growling from a distance, or behaving in a way that makes you nervous.
New Hampshire’s broader self-defense framework reinforces this standard. Under RSA 627:4, you are permitted to use non-deadly force — defined as force not likely to result in death or serious bodily injury — to protect yourself or another individual when you have a reasonable belief that someone is using or is about to use illegal non-deadly force against you. Deadly force carries a higher threshold: you must reasonably perceive an imminent threat of serious bodily injury or death.
Applied to dogs, this means a small dog that is barking at you from across the yard almost certainly does not meet the imminent-threat standard. A large dog that has knocked you to the ground and is actively biting presents a very different picture. The key word throughout New Hampshire law is “imminent” — the danger must be happening right now, not anticipated for later.
In New Hampshire, using deadly force against a trespasser is generally not legal unless there is an immediate threat to personal safety. Property owners may ask trespassers to leave but must avoid excessive force. The same logic applies to animals: the fact that a dog is on your land without permission does not, by itself, authorize deadly force.
Trespassing Alone Is Not Justification in New Hampshire
This is the point where many property owners make a dangerous legal mistake. A dog crossing your property line — even repeatedly, even after you have complained to the owner — does not give you the legal right to shoot it. New Hampshire law requires an active threat or an active attack on livestock, not mere trespass.
Ultimately, the responsibility lies with dog owners to follow leash laws and keep their animals on their own property — but when they fail to do so, your remedy is to contact animal control, not to use a firearm. Shooting a dog that is simply wandering on your land, digging in your garden, or even chasing your cat could expose you to criminal prosecution under the state’s animal cruelty statute.
The correct steps when a neighbor’s dog repeatedly trespasses include documenting each incident with photos or video, filing a formal complaint with your local animal control officer, and contacting local police if the owner refuses to act. Under RSA 436:8, complaints under RSA 644:8 and any other law pertaining to the abuse of domestic animals shall initially be filed with the local law enforcement agency, animal control officer, state police, or sheriff which has jurisdiction over where the animal is located or kept.

Pro Tip: Keep a written log of every incident involving a neighbor’s dog — date, time, what the dog did, and any witnesses. This documentation strengthens your complaint to animal control and protects you legally if the situation escalates.
Firearm Discharge Laws That May Apply in New Hampshire
Even when the use of deadly force against a dog is legally justified under RSA 466:28, you can still face separate legal exposure based on how and where you discharge your firearm. New Hampshire has several statutes that govern firearm use independent of the dog-specific law.
It is unlawful to discharge a firearm from or across a public highway, including the rights of way of a highway, in pursuit of wild birds or animals. If a dog is near a road and your shot crosses that right-of-way, you may be in violation regardless of whether shooting the dog itself was justified.
Municipal ordinances add another layer. Many New Hampshire towns and cities restrict or prohibit firearm discharge within their limits. Before assuming you can legally fire a weapon on your property, check your municipality’s local ordinances. To the extent consistent with federal law, the state of New Hampshire has authority and jurisdiction over the sale, purchase, ownership, use, possession, transportation, licensing, permitting, taxation, or other matter pertaining to firearms in the state — but that state authority does not preempt all local discharge ordinances.
Negligent discharge is also a concern. Negligently discharging a firearm or causing death, injury, or damage to domestic animals or property is prohibited under New Hampshire hunting regulations, and similar negligence standards appear in the criminal code. If a shot intended for a dog strikes a neighbor, a bystander, or their property, you face serious criminal liability well beyond the dog-related statutes.
| Legal Consideration | Relevant Statute | Key Restriction |
|---|---|---|
| Killing a dog (civilian) | RSA 466:28 | Active assault or active livestock attack required |
| Killing a dog (officer) | RSA 466:36 | Law enforcement only; in-act maiming or pursuit |
| Discharge across highway | RSA 207 / hunting regs | Unlawful regardless of justification for the shot |
| Municipal discharge bans | Local ordinances | Varies by town; check before assuming permission |
| Animal cruelty | RSA 644:8 | Applies if shooting falls outside lawful justification |
What Happens After You Shoot a Dog in New Hampshire
If you shoot a dog — even in a situation you believe is fully justified — you should expect law enforcement involvement. Police will determine whether you had the legal right to kill the dog under RSA 466:28, and they will investigate the circumstances before making that determination. You are not the one who decides the shooting was justified; police and, potentially, prosecutors make that call.
Call police immediately after any shooting involving a dog. Do not wait for the dog’s owner to show up and escalate the situation. In at least one documented New Hampshire case, the shooter called police immediately after he shot the dog on his property to report what had happened — a step that factored into how police evaluated the incident. Prompt, transparent reporting demonstrates good faith and gives you control over how the initial account is framed.
Be prepared for the dog’s owner to challenge your account. Disputes about what exactly the dog was doing, whether it was truly “out of the enclosure or immediate care” of its owner, and whether the threat was genuine are common in these cases. In the Hampstead case, the dog’s owners insisted the shooter knew the dog well and had seen her running in their yard in the summer, and they believed the dog was shot because they had complained about the shooter’s target practice in the past. These competing narratives can lead to lengthy investigations even when no charges are ultimately filed.
Civil liability is a separate track from criminal law. Even if police determine no crime was committed, the dog’s owner may still sue you in civil court for the value of the dog and related damages. Dogs are considered personal property under New Hampshire law, and their owners have legal standing to seek compensation.

Penalties for Illegally Killing a Dog in New Hampshire
If your shooting of a dog does not meet the requirements of RSA 466:28, you face potential prosecution under New Hampshire’s animal cruelty statute, RSA 644:8. The penalties depend on your mental state at the time of the act — what the law calls “mens rea.”
The cruelty law describes both misdemeanor and felony offenses. First-time negligent offenses are misdemeanors; second negligent offenses are felonies. Negligence, in this context, means you failed to recognize a substantial and unjustifiable risk that your conduct would harm the animal — for example, shooting at a dog that posed no genuine threat because you misjudged the situation.
The penalties escalate sharply for intentional conduct. Under RSA 644:8, III-a, a person is guilty of a class B felony who purposely beats, cruelly whips, tortures, or mutilates any animal. While shooting a dog is not the same as torture, a prosecutor could pursue felony charges if the circumstances suggest the killing was deliberate and unjustified — for example, shooting a dog that was clearly retreating or posed no threat.
Beyond criminal penalties, conviction carries long-term consequences for animal ownership. The court shall prohibit or limit any person convicted of a felony offense of animal cruelty under RSA 644:8 from having future ownership or custody of other animals for a minimum of 5 years, and may impose any other reasonable restrictions on the person’s future ownership or custody of, or residing or having contact with animals as necessary for the protection of the animals.
A summary of potential penalties appears below:
| Offense Level | Statute | Potential Penalty |
|---|---|---|
| First-time negligent cruelty | RSA 644:8, III | Misdemeanor; possible fines, probation |
| Second negligent offense | RSA 644:8, III | Felony; enhanced penalties |
| Purposeful cruelty / mutilation | RSA 644:8, III-a | Class B felony |
| Felony conviction (any) | RSA 644:8 | 5-year minimum ban on animal ownership |
| Dog owner whose dog attacks livestock | RSA 466:36 | Violation; fine up to $500 |
Note that the dog’s owner is not without consequences either. The owner or owners of any dog caught in the act of maiming or in close pursuit of deer, moose, caribou, sheep, cattle, swine, poultry, or any domestic animal shall be guilty of a violation and may be fined up to $500. That does not authorize you to shoot the dog as a substitute for that legal process, but it does mean the law holds irresponsible dog owners accountable through their own channel.

Important Note: When in doubt, do not shoot. Contact your local animal control officer or police non-emergency line first. The legal risk of acting outside RSA 466:28 far outweighs the inconvenience of making a phone call.
New Hampshire law does give property owners a meaningful — though carefully bounded — right to defend themselves and their livestock from dog attacks. RSA 466:28 is real protection, but it demands an active, present-tense threat. A dog that is trespassing, barking, or that caused damage in the past does not clear that bar. Understanding exactly where the law draws the line is the difference between a justified act of defense and a criminal charge.
