How to Report Animal Cruelty in Colorado: Laws, Contacts, and Penalties
August 1, 2026
Witnessing animal cruelty or neglect is distressing — and knowing what to do next can feel just as overwhelming. Colorado has clear laws that define what qualifies as cruelty, who is responsible for reporting it, and what happens once a complaint is filed. Whether you spotted a neighbor’s dog left outside without shelter in a snowstorm or witnessed something far more severe, your report could be the difference between an animal’s suffering and its safety.
This guide walks you through every step of the reporting process in Colorado, from recognizing abuse to understanding the criminal consequences offenders face. You do not need to be certain that a crime has occurred to make a report — suspicion is enough to get the right people involved.
What Counts as Animal Cruelty in Colorado
Colorado’s animal cruelty statute is found at C.R.S. § 18-9-202, which defines two tiers of offense: standard cruelty and aggravated cruelty. Understanding the difference matters because the penalties vary significantly between them.
Standard cruelty covers a wide range of conduct. A person commits cruelty to animals if they knowingly, recklessly, or with criminal negligence overdrive, overload, overwork, torment, deprive of necessary sustenance, unnecessarily or cruelly beat, allow to be housed in a manner that results in chronic or repeated serious physical harm, carry or confine in or upon any vehicle in a cruel or reckless manner, engage in a sexual act with an animal, or otherwise mistreat or neglect any animal — or, having charge or custody of any animal, fail to provide it with proper food, drink, or protection from the weather consistent with the species, breed, and type of animal involved, or abandon an animal.
In plain terms, this means neglect is just as actionable as active abuse. Under Colorado law, “mistreat” means every act or omission that causes or unreasonably permits the continuation of unnecessary or unjustifiable pain or suffering, while “neglect” means failure to provide food, water, protection from the elements, or other care generally considered normal and accepted for an animal’s health and well-being consistent with the species, breed, and type of animal.
Aggravated cruelty applies when the conduct is intentional and severe. A person commits aggravated cruelty to animals if they knowingly torture, needlessly mutilate, or needlessly kill an animal — or knowingly kill or cause serious bodily injury that results in the death of a law enforcement animal, whether the law enforcement animal is on duty or not on duty.
Colorado law also covers animals in commercial settings. The Pet Animal Care Facilities Act (PACFA), part of the Colorado Department of Agriculture, regulates pet stores, breeders, groomers, and doggy day care centers operating in Colorado, and will investigate complaints concerning the health, safety, and treatment of pets by third parties, as well as complaints concerning the condition of facilities where pets are raised or kept.
Key Insight: You face a separate charge for each animal involved. If two dogs are neglected in the same household, that is two separate cruelty counts under Colorado law.
Wildlife cruelty falls under a different authority. Matters involving wildlife may be handled by law enforcement or Colorado Parks and Wildlife Officers. For a broader look at how Colorado defines and prosecutes animal cruelty, see our guide to animal cruelty laws in Colorado.
Who Can Report Animal Cruelty in Colorado
Any person in Colorado can report suspected animal cruelty — there is no requirement that you witnessed the incident directly or that you have proof beyond a reasonable doubt. It is strongly suggested that even if you only suspect a problem, you make a report. Agencies are trained to investigate and determine whether a violation has occurred.
Reports can be made anonymously in most cases. Your name in a complaint can be kept anonymous from public records. If you prefer complete anonymity, Crime Stoppers offers an additional option. Crime Stoppers offers a guaranteed anonymous reporting process, and if a tip results in a citation or arrest, you may be eligible for a reward.
In Denver, you can report anonymously to Metro Denver Crime Stoppers and may receive up to a $2,000 reward for tips leading to arrests.
Veterinarians, shelter workers, law enforcement officers, and members of the public all have standing to report. The difference between the general public and licensed veterinarians is that vets carry a legal obligation — covered in the next section.
Who Is Required to Report Animal Cruelty in Colorado
Colorado is one of a minority of states that imposes a mandatory reporting duty on licensed veterinarians. Colorado requires veterinarians to report suspected animal cruelty. Under CRS 12-315-120, a licensed veterinarian who has reasonable cause to suspect that an animal has been subjected to cruelty or animal fighting must report the situation to local law enforcement or the Bureau of Animal Protection. This is a mandatory duty, not a discretionary one, which means a vet who notices signs of abuse during a routine exam cannot simply look the other way.
About 24 states place a mandatory duty upon state-licensed veterinarians (and sometimes vet techs) to report suspected animal cruelty to the proper authorities, including California, Colorado, Hawaii, Illinois, Minnesota, Oklahoma, and West Virginia.
Veterinarians who report in good faith are protected from legal blowback. Colorado’s law protects veterinarians by providing them with immunity from civil and criminal liability when reports are made in good faith. This immunity removes one of the main reasons vets historically hesitated to get involved.
Beyond veterinarians, peace officers who witness excessive force by a law enforcement animal’s handler also carry a reporting obligation. A peace officer who witnesses the use of excessive force by a law enforcement animal, as permitted by the animal’s handler, must report the excessive force to the officer’s or handler’s supervisor.
For the general public, reporting is not legally required — but it is strongly encouraged. Studies indicate that people who intentionally harm animals may be more likely to commit violent crimes towards people, and reporting animal abuse helps prevent future violence and improve the quality of life for everyone in the community.
Important Note: If you are a licensed veterinarian in Colorado and you fail to report suspected cruelty, you are not simply overlooking an ethical obligation — you are violating a statutory duty under CRS 12-315-120.
How to Report Animal Cruelty in Colorado
The right agency to contact depends on where you are in the state and the nature of the situation. Since animal cruelty occurs in a wide variety of settings, jurisdictions, and situations, the specifics of each occurrence will dictate what agency is responsible for investigation. While some larger municipal or county jurisdictions may have specific animal control units and officers, other areas may rely solely on their law enforcement officers or investigators commissioned by the Colorado Department of Agriculture Bureau of Animal Protection.
Here is a breakdown of your main reporting options:
- Emergency situations: Law enforcement should always be contacted in emergency situations (911) and/or if there is knowledge regarding animal cruelty in conjunction with other criminal behavior and/or violence and/or human maltreatment issues.
- Colorado Bureau of Animal Protection (BAP): The Bureau of Animal Protection serves as a support mechanism to local law enforcement agencies in conducting animal cruelty and neglect investigations. You can file a complaint through the Colorado Department of Agriculture’s BAP complaint page.
- Local animal control or humane society: The first step for reporting animal cruelty or neglect is to contact local law enforcement, animal control, or a local humane society. Many of these local agencies have BAP agents on staff and resources to respond rapidly to public reports of animal mistreatment or neglect.
- Colorado Humane Society / Crime Stoppers tip line: You can report animal abuse by visiting Colorado’s Bureau of Animal Protection website and clicking your county to find local contact numbers, or by calling Colorado’s Humane Society at (720) 913-7867. You can also text 274637 (CRIMES) or fill out their online complaint form.
- PACFA (pet care facilities): Report concerns about breeders, pet stores, or boarding facilities on the Complaint Form to the Pet Animal Care Facilities Act (PACFA) Program. The email for PACFA is cda_pacfa@state.co.us, and their phone number is (303) 869-9146.
Regional organizations also handle reports for specific counties. The Dumb Friends League can investigate animal cruelty and neglect in Adams, Arapahoe, Elbert, Jefferson, Douglas, Broomfield, Weld, and Denver counties. To report animal neglect or cruelty to the Denver Dumb Friends League, call 303-923-0022 or file an online report. The Humane Society of the Pikes Peak Region can investigate animal cruelty and neglect in Arapahoe, Douglas, El Paso, and Pueblo counties, and can be reached at 719-473-1741.
When you make your report, document as much detail as possible. Provide the dates, times, and locations of the incident or suspected incident, document patterns of progressively more harmful behaviors, and provide the names and addresses of involved parties if known. Photographs or video evidence, if you can safely gather them, are also helpful.
Pro Tip: If you are unsure which agency covers your area, contact Humane Colorado at 303-751-5772 — they can direct you to the right local authority.
What Happens After You Report in Colorado
Once a report is filed, the investigation process begins. Enforcement of animal cruelty laws in Colorado involves collaboration between law enforcement agencies, animal control officers, and animal welfare organizations. Investigations into allegations of animal cruelty typically begin with reports from concerned citizens, veterinarians, or animal welfare professionals.
Most reports are resolved through education, assistance, and enforcement. Not every case results in criminal charges — investigators may first attempt to educate the animal’s owner about proper care standards and provide resources. If the situation is serious or the owner is uncooperative, the case moves toward formal enforcement.
If an officer determines an animal is in immediate danger, they have the authority to remove it. A peace officer having authority to act pursuant to this section may take possession of and impound an animal that the officer has probable cause to believe is a victim of a violation and is endangered if it remains with the owner or custodian.
Once impounded, the animal’s care becomes the owner’s financial responsibility. The owner or custodian of an animal that is the subject of a motion brought under this section shall be liable for the cost of the care, keeping, transport, or disposal of the animal. If the animal is suffering severely, a licensed veterinarian may authorize euthanasia without a court order.
After the investigation, the responding agency may refer the case to prosecutors if criminal charges are warranted. The strength of your documentation — dates, photos, witness accounts — directly affects how well investigators can build a case.
Penalties for Animal Cruelty in Colorado
Colorado imposes criminal penalties that escalate based on the severity of the offense, prior convictions, and whether the victim was a service or law enforcement animal. Here is how the penalty structure breaks down under C.R.S. § 18-9-202:
| Offense | Classification | Potential Penalties |
|---|---|---|
| Standard cruelty (first offense) | Class 1 misdemeanor | Up to 364 days in jail; $500–$1,000 fine |
| Standard cruelty (second or subsequent offense) | Class 6 felony | Prison term; $1,000 mandatory minimum fine; treatment program required |
| Aggravated cruelty (first offense) | Class 6 felony | 1–1.5 years prison; $1,000–$100,000 in fines |
| Aggravated cruelty to a law enforcement animal | Felony (enhanced) | $2,000 mandatory minimum fine; restitution for training/replacement costs |
Non-aggravated animal cruelty is a class 1 misdemeanor for a first offense, with penalties including up to 364 days in jail and/or $500 to $1,000 in fines, and the judge has discretion to order anger management treatment.
A first offense of aggravated animal cruelty under CRS 18-9-202 is a class 6 felony. A first-time offense carries a potential prison term of one to one and a half years, with one year of mandatory parole.
Courts also have authority to order treatment programs. In addition to any other sentence imposed, the court may order an offender to complete an anger management treatment program, a mental health treatment program, or any other appropriate treatment program designed to address the underlying causative factors for the violation. The court shall order an evaluation to be conducted prior to sentencing to assist the court in determining an appropriate sentence.
For law enforcement animals specifically, House Bill 1074 gives police canines and horses their own legal category, and the law adds new consequences — a mandatory minimum fine of $2,000 plus restitution for costs to rehabilitate or replace the hurt or killed animal.
Animal cruelty convictions can also carry immigration consequences. Animal cruelty is a deportable offense, and it is vital for non-citizens facing criminal charges to contact an attorney right away, as non-citizens convicted of it face removal from the U.S.
Finally, fines collected under the statute serve a direct purpose. Any fines collected shall be transmitted to the state treasurer, who shall then transmit the same to the county where the offense occurred for deposit in the general fund to be used for the care of the animals involved in the offense, if required, or, if not required, for any other lawful purpose.
