New Mexico takes animal cruelty seriously, and the state’s criminal code spells out clear consequences for those who harm, neglect, or exploit animals under their care. Whether you witnessed a neighbor’s dog left without food and water for days, or you are trying to understand your own legal obligations as a pet or livestock owner, knowing how these laws work matters.
The primary statute governing animal cruelty in New Mexico is N.M.S.A. § 30-18-1, which covers everything from basic neglect to extreme cruelty. This article walks through each layer of that law — what conduct is prohibited, how charges are classified, who enforces the rules, and what penalties a conviction can bring.

What Counts as Animal Cruelty in New Mexico
New Mexico law defines animal cruelty in two broad ways: active harmful conduct and a failure to act. Cruelty to animals consists of a person negligently mistreating, injuring, killing without lawful justification, or tormenting an animal — or abandoning or failing to provide necessary sustenance to an animal under that person’s custody or control. Both categories carry real criminal exposure, even if the harm was not intentional.
The statute covers domesticated animals and wild animals that have been brought into captivity. The law applies only to domesticated animals and wild animals previously reduced to captivity; treatment of free-roaming wild animals is governed by the hunting and fishing laws in Chapter 17, which preempt this section. So if you see a stray cat being harmed, it falls under this statute — but a hunter’s actions toward wild game in the field generally do not.
As used in the statute, “animal” does not include insects or reptiles. This means snakes, lizards, and similar reptiles fall outside the scope of New Mexico’s animal cruelty law, though other laws may still apply depending on the circumstances.
Intentional cruel actions include intentionally or maliciously torturing, mutilating, injuring, or poisoning an animal; maliciously killing an animal; killing an animal without lawful justification; or tormenting an animal. Courts have also confirmed that acting with “willful disregard” for an animal’s safety — even without a specific intent to cause suffering — can satisfy the criminal standard.
Key Insight: New Mexico courts have held that evidence a defendant acted intentionally, purposely, or deliberately in harming an animal is enough to establish “willful disregard” for that animal’s safety under the cruelty statute.
Animal Neglect Laws in New Mexico
Neglect is one of the most common forms of animal cruelty investigated in New Mexico, and the law treats it as a criminal offense in its own right. Cruel treatment includes situations where a person has failed to act or failed to provide necessary food or care. Failing to act rises to the level of cruelty when it involves negligently mistreating, abandoning, or failing to provide necessary sustenance.
What counts as “necessary sustenance” includes food, clean water, and adequate shelter. A real-world example from New Mexico case law illustrates how seriously courts treat neglect: a defendant was found guilty where the state established that the defendant kept numerous dogs chained outdoors, some were not given sufficient food, water, or shelter, some were emaciated to the degree that their ribs and hip bones were visibly protruding, some were infested with ticks, and some had visible injuries and open sores.
Animal cruelty is a concern in New Mexico, especially with equines such as horses, donkeys, and mules, but so is the prosecution of those who do not adequately feed and care for their livestock. If you own horses or other livestock in New Mexico, the same neglect standards apply — and law enforcement actively investigates these cases.
Under New Mexico law, domestic equines are considered livestock, and enforcement of cruelty laws involving livestock falls under the jurisdiction of the New Mexico Livestock Board. After responding to a call, investigators examine the livestock and determine a course of action: either immediate seizure or working with the owner to monitor the care of the animals under investigation. If the life or health of the animal is in danger, the animal may be seized and taken to a veterinarian for immediate evaluation.
Misdemeanor vs. Felony Animal Cruelty in New Mexico
New Mexico draws a clear legal line between standard animal cruelty — which starts as a misdemeanor — and conduct serious enough to qualify as a felony from the first offense. Understanding where your conduct falls on that spectrum is important, because the consequences differ significantly.
| Charge Level | Trigger | Classification | Basic Sentence | Fine |
|---|---|---|---|---|
| Standard Cruelty (1st–3rd offense) | Negligent mistreatment, tormenting, abandonment, failure to provide sustenance | Misdemeanor | Up to 364 days | Up to $1,000 |
| Standard Cruelty (4th+ offense) | Repeat conviction | Fourth-Degree Felony | 18 months | Up to $5,000 |
| Extreme Cruelty | Intentional/malicious torture, mutilation, poisoning, or killing | Fourth-Degree Felony | 18 months | Up to $5,000 |
Whoever commits cruelty to animals is guilty of a misdemeanor. Upon a fourth or subsequent conviction, the offender is guilty of a fourth-degree felony. This escalation provision means that repeat offenders face dramatically increased consequences even if each individual act would otherwise be classified as a misdemeanor.
A misdemeanor carries a basic sentence of 364 days in prison and a fine of $1,000, followed by one year of parole. A fourth-degree felony carries a basic sentence of 18 months in prison and a fine of $5,000, followed by one year of parole. These are the baseline sentences — courts may adjust them based on circumstances.

Aggravated Animal Cruelty and Special Circumstances in New Mexico
Beyond the standard cruelty statute, New Mexico has enacted additional laws targeting the most serious forms of animal abuse. These include extreme cruelty, animal fighting, bestiality, and harm to police and service animals — each carrying its own set of penalties.
Extreme Cruelty
Extreme cruelty to animals consists of a person intentionally or maliciously torturing, mutilating, injuring, or poisoning an animal. Whoever commits extreme cruelty to animals is guilty of a fourth-degree felony. Unlike standard cruelty, extreme cruelty is a felony on the very first offense — no prior convictions are required to trigger felony-level prosecution.
Animal Fighting
Dog fighting and cockfighting are addressed under N.M.S.A. § 30-18-9. Cockfighting was previously treated differently in New Mexico, but a 2007 amendment removed a prior exemption that had allowed it. Animal fighting operations are now prosecuted as serious criminal offenses.
Bestiality
In 2023, New Mexico passed a law to outlaw bestiality. Under N.M.S.A. § 30-9A-3, bestiality consists of a person engaging in sexual contact with an animal, and a person who commits bestiality is guilty of a fourth-degree felony. A person who commits aggravated bestiality is guilty of a third-degree felony. Following a conviction, all animals under the direct care and control of the convicted person must be seized and turned over to an agent of the New Mexico Livestock Board or to an animal control agency operated by the state or a local government.
Injury to Police and Service Animals
New Mexico law under § 30-18-13 specifically protects police dogs, police horses, and fire dogs. Whoever commits injury to a police dog, police horse, or fire dog when the injury causes serious physical injury or death, or directly causes the destruction of the animal, is guilty of a fourth-degree felony. A person convicted of this offense may be ordered to make restitution for the animal’s veterinary bills or replacement costs if the animal is permanently disabled, killed, or destroyed.
Exemptions Under New Mexico’s Animal Cruelty Laws
New Mexico’s animal cruelty statute includes several explicit exemptions for activities the legislature has determined fall outside the scope of criminal animal cruelty. If you work in agriculture, veterinary medicine, or certain regulated industries, these exemptions are relevant to your daily operations.
The provisions of the cruelty statute do not apply to: fishing, hunting, falconry, taking and trapping as provided in Chapter 17; the practice of veterinary medicine as provided in Chapter 61, Article 14; rodent or pest control as provided in Chapter 77, Article 15; the treatment of livestock and other animals used on farms and ranches for the production of food, fiber, or other agricultural products when the treatment is in accordance with commonly accepted agricultural animal husbandry practices; the use of commonly accepted Mexican and American rodeo practices unless otherwise prohibited by law; and research facilities licensed pursuant to federal law.
The agricultural husbandry exemption is not a blank check, however. If there is a dispute as to what constitutes commonly accepted agricultural animal husbandry practices or commonly accepted rodeo practices, the New Mexico Livestock Board shall hold a hearing to determine if the practice in question qualifies. Courts have confirmed that the district court — not the livestock board — is the proper initial forum for raising such disputes in criminal proceedings.
It is also worth noting that lawful justification for killing an animal means humanely destroying a sick or injured animal, or protecting a person or animal from death or injury due to an attack by another animal. This covers situations like humanely euthanizing a suffering pet or defending livestock from a predator attack.
Pro Tip: If you are a livestock owner and unsure whether a particular husbandry practice could be considered cruelty, consult the New Mexico Livestock Board or a local agricultural extension office before proceeding.
Who Enforces Animal Cruelty Laws in New Mexico
Enforcement of animal cruelty laws in New Mexico is shared across several agencies, depending on the type of animal involved and where the alleged cruelty occurred.
- Local animal control officers — Municipal and county animal control agencies handle most companion animal cases within city and county limits.
- County sheriffs and state police — In rural or unincorporated areas, sheriff’s deputies and New Mexico State Police officers have authority to investigate and make arrests for animal cruelty violations.
- New Mexico Livestock Board — Under New Mexico law, domestic equines are considered livestock, and enforcement of cruelty laws involving livestock falls under the jurisdiction of the New Mexico Livestock Board. Livestock inspectors have authority to arrest persons for violations of Article 18.
- Peace officers with warrant authority — A peace officer who reasonably believes that the life or health of an animal is endangered due to cruel treatment may apply to the district court, magistrate court, or metropolitan court in the county where the animal is located for a warrant to seize the animal.
In New Mexico there are a limited number of animal control officers, sheriff’s deputies, and others charged with enforcing animal cruelty laws. They are often responsible for enforcing these laws over large geographic areas of the state, and the time they can allocate to animal cases is often limited. Citizens who can observe and report abuse or neglect are therefore vital to protecting both wild and domesticated animals in New Mexico.

How to Report Animal Cruelty in New Mexico
If you suspect an animal is being abused or neglected, reporting it promptly and correctly gives law enforcement the best chance of helping that animal. Knowing what information to gather — and what not to do — makes your report far more effective.
When you call, be ready to provide the number and type of animals, the address or location where abuse is alleged, directions to or a description of the property, the name of the alleged abuser, a description of the nature of the abuse or neglect, whether animals are visible from a public road, and whether there are other witnesses.
Once you have your documentation ready, call your local animal control officer, police, sheriff, or whoever has jurisdiction in the area of the abuse. Know where the abuse is located and who has jurisdiction — whether that is municipal animal control, county animal control, the county sheriff, or state police.
Documenting what you observe is also important. Being able to see the actual scene and condition of the animal is the best evidence. Photographs do a good job of convincing a judge or jury of the animal’s true condition, and video can be even more compelling, especially in cases of a person actively abusing an animal.
One critical caution: some animal welfare advocates may be tempted to enter private property to help an allegedly maltreated animal, but law enforcement warns against entering private property for any reason without owner permission. Doing so could expose you to a criminal trespass charge and may compromise the case against the abuser. Your information and evidence can help law enforcement officials obtain a warrant.
You can also contact Animal Protection New Mexico for guidance on documenting and reporting suspected cruelty cases, or reach out to your local animal shelter for referrals to the appropriate enforcement agency.
Penalties and Consequences for Animal Cruelty Convictions in New Mexico
A conviction for animal cruelty in New Mexico carries more than just jail time and fines. Courts have a range of tools they can use — and in some cases must use — to address the underlying conduct and protect animals going forward.
Criminal Sentences
If you are found guilty of cruelty to animals — including failing to provide food or water, failing to provide veterinary care, or any other act deemed not to be extreme cruelty — you can be charged with a misdemeanor, which carries a basic sentence of 364 days in prison and a fine of $1,000, followed by one year of parole. Extreme cruelty, as a fourth-degree felony, carries an 18-month baseline sentence and a $5,000 fine.
Mandatory and Discretionary Court Orders
- The court may order a person convicted of cruelty to animals to participate in an animal cruelty prevention program or an animal cruelty education program.
- The court may also order a person convicted of cruelty to animals or extreme cruelty to obtain psychological counseling for treatment of a mental health disorder if, in the court’s judgment, the mental health disorder contributed to the commission of the criminal offense.
- The offender bears the expense of participating in an animal cruelty prevention program, education program, or psychological counseling ordered by the court.
- If a child is adjudicated of cruelty to animals, the court shall order an assessment and any necessary psychological counseling or treatment of the child.
Financial Liability
In addition to fines and penalties, individuals convicted and sentenced may be responsible for other charges, including court costs, impound fees, or veterinary expenses. Under N.M.S.A. § 30-18-1.3, upon conviction, a defendant is liable for the reasonable cost of boarding the animal and all necessary veterinary examinations and care provided to the animal.
Animal Seizure and Security
An agent of the New Mexico Livestock Board, an animal control agency, or an animal shelter in whose custody a cruelly treated animal has been placed may petition the court to request that the animal’s owner post security to indemnify the costs incurred to care for the seized animal pending the disposition of criminal charges. If the owner does not post security within fifteen days after the issuance of the order, or if the owner cannot be located after reasonable attempts, the animal may be deemed abandoned and relinquished for adoption or humane destruction. Nothing in this provision prohibits an owner from voluntarily relinquishing an animal to an animal control agency or shelter in lieu of posting security.
For context on how other states structure their penalty systems, you can compare New Mexico’s approach with animal cruelty laws in Michigan, animal cruelty laws in Ohio, and animal cruelty laws in Florida. You can also review the frameworks used in New York, Virginia, Georgia, and Washington to see how penalty structures vary by state.
New Mexico’s animal cruelty framework is clear: from misdemeanor neglect to fourth-degree felony charges for extreme cruelty, the law draws meaningful distinctions and imposes real consequences. If you witness suspected abuse, document what you can safely observe, stay off private property, and contact your local animal control agency, sheriff, or the New Mexico Livestock Board right away. Timely, accurate reporting is the most effective thing you can do to protect an animal in distress.
