How to Report Animal Cruelty in Massachusetts: Laws, Steps, and Penalties
July 14, 2026
Animal cruelty is a felony in Massachusetts, and the state gives both private citizens and designated professionals the tools to act when they witness it. Whether you see a neighbor’s dog left outside in dangerous weather or suspect an animal is being starved or beaten, knowing how the reporting system works can make the difference between an animal suffering longer and getting the help it needs.
This guide walks you through what the law defines as animal cruelty, who can and must report it, exactly how to file a report, what investigators do after you call, and what penalties offenders face under Massachusetts law.
What Counts as Animal Cruelty in Massachusetts
Massachusetts General Law Chapter 272, Section 77 is the state’s primary anti-cruelty statute. It covers whoever overdrives, overloads, overworks, tortures, torments, deprives of necessary sustenance, cruelly beats, mutilates, or kills an animal, as well as whoever, having the charge or custody of an animal, inflicts unnecessary cruelty upon it or unnecessarily fails to provide it with proper food, drink, shelter, sanitary environment, or protection from the weather.
In practice, that broad language covers a wide range of situations. Prohibited conduct includes failing to provide an animal with food and water, sanitation, protection from the elements, or proper veterinary care; overworking an animal to the point of exhaustion and collapse; and willfully allowing an animal to be tortured, to suffer, or to be put in danger of bodily injury or death — which can include mutilation, beatings, and burnings.
Leaving an animal in a parked car on a hot day — even 70 degrees can be too hot — and hoarding a large quantity of animals in a single small location are also covered. Whether as owner or custodian, any person who willfully abandons an animal is in violation of Massachusetts state cruelty laws.
Beyond Section 77, several related statutes address specific conduct. M.G.L. c. 140, § 174E restricts how dogs may be chained or tethered and kept outside, and M.G.L. c. 140, § 174F addresses leaving an animal in a hot or cold vehicle or removing an animal in danger from a vehicle. Animal fighting is addressed separately under M.G.L. c. 272, § 94, and animal fighting is a felony in Massachusetts.
Important Note: The law applies to both active abuse and passive neglect. You do not need to witness a physical attack to have grounds for a report — inadequate food, water, shelter, or veterinary care are all actionable under M.G.L. c. 272, § 77.
Who Can Report Animal Cruelty in Massachusetts
Anyone who witnesses or reasonably suspects animal cruelty in Massachusetts can make a report. You do not need to be certain abuse is occurring — reasonable suspicion is enough. The MSPCA Law Enforcement department accepts anonymous calls, and all calls are treated as confidential.
This means that if you are a neighbor, passerby, friend, or family member who observes something that concerns you, you have every right to contact authorities. If you ever witness animal cruelty, stay away from the abuser for your own safety. If you can, try to get photos or videos for evidence, then contact animal control and the police right away.
Being thorough before you call strengthens the case. Animal abuse is a serious claim, so before you contact the police, make sure you are certain of what happened. For example, you may think your neighbor is abusing their dog because it is always out in the yard without food — but there could be food in an area you cannot see, or your neighbor might feed the dog at odd hours. Document what you observe with dates, times, and photographs whenever it is safe to do so.
Massachusetts also recognizes a connection between animal abuse and other forms of household violence. Research shows that animals are often abused by people who also abuse their children or spouse. Children who witness or participate in animal abuse may show signs of aggression that can lead to criminal activity as they age. If a child is abusing an animal, it is likely a sign that other forms of abuse are occurring in the home. Reporting animal cruelty may therefore protect human victims as well.
Who Is Required to Report Animal Cruelty in Massachusetts
While any member of the public may report, certain professionals are legally required to do so. In 2014, animal abuse laws in Massachusetts were greatly expanded. The Act Protecting Animal Welfare and Safety (PAWS) increased punishments for existing animal abuse crimes and created a mandatory requirement for veterinarians to report abuse.
Under M.G.L. c. 112, § 58B, a veterinarian who, while in the normal course of business, observes an animal whom such veterinarian knows or reasonably suspects has been the victim of animal cruelty prohibited under sections 77 or 94 of chapter 272 shall report said suspected animal cruelty to a police officer or special state police officer. A veterinarian duly registered who reports, in good faith and in the normal course of business, a suspected act of cruelty to animals shall not be liable for doing so — meaning the law provides immunity from civil or criminal action for good-faith reporters.
The mandatory reporting obligation extends beyond veterinarians. Several categories of state employees must also act when they encounter suspected abuse in the course of their work:
- Under M.G.L. c. 19C, § 14, any investigator designated by the Disabled Persons Protection Commission, when acting in their professional capacity, who has knowledge of or observes an animal they know or reasonably suspect has been the victim of animal cruelty, abuse, or neglect, may report to the entities that investigate reports of animal cruelty as described in section 57 of chapter 22C, or any local animal control authority.
- Under M.G.L. c. 19A, § 42A, an employee of the Department of Elder Affairs or its designated agency, when acting in their professional capacity, who has knowledge of or observes an animal they know or reasonably suspect has been a victim of animal cruelty, abuse, or neglect, may report to the entities that investigate reports of animal cruelty or any local animal control authority.
- Under M.G.L. c. 119, § 21, animal control officers are mandatory reporters for child abuse. Additionally, employees of the Department of Social Services may report animal abuse they reasonably suspect in the course of their professional capacity or within the scope of their employment, and a person making such a report in good faith is immune from civil or criminal action.
For mandatory reporters, the report may be made within 2 working days of receiving the information concerning the animal, by facsimile transmission, a written report, or by telephone. In cases where an immediate response may be necessary to protect the health and safety of the animal, the report should be made by telephone as soon as possible.
Pro Tip: If you are a veterinarian or state employee covered by a mandatory reporting statute, document your observations in writing — including dates, clinical findings, and photographs — before making your call. This record supports the investigation and protects you professionally.
How to Report Animal Cruelty in Massachusetts
Massachusetts gives you several channels for reporting, depending on the urgency of the situation. Choosing the right one helps ensure the fastest and most appropriate response.
In an Emergency
If you know or suspect that an animal is in imminent danger of serious bodily harm or death, immediately contact your local law enforcement agency or the Massachusetts State Police. Call 911 for the fastest response time and to detain someone mistreating an animal in a public space.
Non-Emergency Reports
In non-emergency situations where you know of or suspect animal abuse, neglect, or cruelty, contact your municipal animal control officer, often listed on your town’s website. You can also reach out to your local police. You may have to make a few calls, but be persistent.
Two statewide organizations also accept reports and have law enforcement authority in Massachusetts:
- MSPCA Law Enforcement: Call (617) 522-6008 or (800) 628-5808, Monday through Friday, 9 a.m. to 4:30 p.m. When calling after hours, leave a brief message with your name and phone number. The MSPCA Law Enforcement voicemail is not monitored during weekends, nights, or holidays, so messages left will not be received until the next business day. In the event of an emergency after hours, contact local police or animal control.
- Animal Rescue League of Boston (ARL): Contact the Animal Rescue League of Boston at 617-426-9170 (Option 2) or email [email protected].
For pet shop complaints specifically, the Massachusetts Department of Agricultural Resources (MDAR) licenses pet shops and various other animal businesses in the state. Complaints about animal health at pet shops should be directed to MDAR. Concerns about other aspects of pet stores can go to the Office of Consumer Affairs and Business Regulation, the Attorney General, and/or MDAR.
What to Include in Your Report
The more detail you provide, the easier it is for investigators to act quickly. Include the following when you report:
- The address or location where the animal is being kept
- A description of the animal (species, breed, color, approximate age)
- A description of what you observed, including dates and times
- The name or description of the person responsible, if known
- Any photos or videos you were able to safely capture
- Your contact information (even for anonymous reports, a callback number helps investigators follow up)
You can also compare your observations to other animal welfare situations in the state. For context on the kinds of animals protected under Massachusetts law, see our guides to venomous animals in Massachusetts and endangered animals in Massachusetts.
What Happens After You Report in Massachusetts
Once a report is filed, law enforcement or a special state police officer will investigate. Under M.G.L. c. 272, § 84, sheriffs, deputy sheriffs, constables, and police officers shall prosecute all violations of sections 77 through 81 that come to their notice. This means officers are not simply permitted to act — they are required to pursue violations they become aware of.
The colonel of the state police may appoint, at the request of the MSPCA, the Animal Rescue League of Boston, and several other named humane organizations, duly accredited agents of those organizations as special state police officers. These officers carry full law enforcement authority in animal cruelty cases alongside local police and animal control.
If the investigation uncovers probable cause, investigators can seek a search warrant. If complaint is made to a court or magistrate that there is reasonable cause to believe that cruelty laws have been or are being violated in any particular building or place, the court or magistrate shall issue a search warrant authorizing officers to search that building or place.
When an animal is seized, the legal process does not end there. If an animal is seized or impounded pursuant to section 77 or 94 of chapter 272 resulting in the issuance of a criminal complaint or a criminal indictment, the authority or prosecuting agency may file a petition with the court requesting that the person from whom the animal was seized be ordered to post a security.
The security must be in an amount sufficient to cover the reasonable expenses incurred by the authority that has custody of the seized animal. Expenses are calculated from the date of seizure and continue until the authority ends custody, and the amount must cover a period of not less than 30 days. Failure to post the security within the appointed time is deemed an immediate forfeiture of the seized animal to the authority.
Key Insight: After you file a report, you may not receive regular updates on the investigation. This is normal. Investigators are bound by confidentiality rules and active case protocols. If the situation worsens or you observe new incidents, call again — each new report adds to the record.
Upon conviction, the defendant must forfeit to the custody of any society incorporated under the laws of the commonwealth for the prevention of cruelty to animals, or for the care and protection of homeless or suffering animals, the animal whose treatment was the basis of the conviction.
Penalties for Animal Cruelty in Massachusetts
In Massachusetts, violation of the animal cruelty statute is a felony. The penalties are substantial and have been strengthened over time.
| Offense | Prison Term | Fine | Statute |
|---|---|---|---|
| First offense (M.G.L. c. 272, § 77) | Up to 7 years (state prison) or up to 2.5 years (house of correction) | Up to $5,000 | M.G.L. c. 272, § 77 |
| Subsequent offenses | Up to 10 years | Up to $10,000 | M.G.L. c. 272, § 77 |
| Animal fighting (M.G.L. c. 272, § 94) | Felony; penalties under § 77 apply | Per § 77 schedule | M.G.L. c. 272, § 94 |
The operative anti-cruelty statute provides that whoever overdrives, overloads, overworks, tortures, torments, deprives of necessary sustenance, cruelly beats, mutilates, or kills an animal, or knowingly and willfully authorizes or permits it to be subjected to unnecessary torture, suffering, or cruelty of any kind shall be punished by imprisonment in the state prison for not more than 7 years or imprisonment for not more than 2.5 years, or by a fine of not more than $5,000, or by both such fine and imprisonment.
A defendant’s first violation could result in a prison sentence of up to 7 years and a maximum fine of $5,000. The punishment is enhanced for any subsequent violation: up to 10 years in prison with a fine not to exceed $10,000.
Beyond fines and imprisonment, a conviction carries additional consequences. A person convicted of a crime of cruelty to an animal shall be prohibited from working in any capacity that requires contact with an animal, including a commercial boarding or training establishment, shelter, animal control facility, pet shop, grooming facility, commercial breeder service, veterinary hospital or clinic, or animal welfare society or other nonprofit organization incorporated for the purpose of providing for and promoting the welfare, protection, and humane treatment of animals.
Massachusetts courts have also addressed edge cases, such as sanitation failures. In one appellate ruling cited by the Law Office of Justin R. McCarthy, the court found that large accumulations of fecal matter in an animal’s living space could support a conviction. Officers testified that there was a large accumulation of feces in the kennels, and at least two dogs were shut in those kennels and forced to move around and step in their own waste.

Take Action When You See Something
Massachusetts has built a layered enforcement system that depends on people speaking up. Law enforcement officers, MSPCA agents, ARL investigators, and animal control officers all have the authority to investigate and prosecute — but they can only act on what they know about.
If you see an animal that appears to be suffering, neglected, or abused, you have both the right and the practical means to report it. Call 911 for emergencies, contact the MSPCA or ARL for non-urgent concerns, and reach your local animal control officer for ongoing situations. Document what you observe, report it clearly, and let the system take it from there.
