Oregon animal laws sit across several chapters of the Oregon Revised Statutes and reach almost everyone who lives with, works with, or lives near an animal. They set a floor of care every owner must meet, grade cruelty and neglect from misdemeanors up to a five-year felony, make dog owners strictly liable for bite injuries, ban most private ownership of exotic species, and split the state into zones that decide whether you fence livestock in or fence them out. What follows is a practical walkthrough of the rules most likely to matter to you.
Minimum Care Every Owner Must Provide
A “domestic animal” under Oregon law is any animal a person owns or possesses, other than livestock or equines. Every owner has to provide enough food to maintain a healthy body weight, open access to clean drinking water (snow and ice do not count), adequate shelter against wind, rain, snow, and sun, bedding that keeps the animal dry and warm, and sanitary living conditions.1Oregon Public Law. Oregon Code 167.310 – Definitions for ORS 167.310 to 167.351
Tethering has its own rule. You cannot tether a domestic animal for more than ten hours in any twenty-four-hour period. The tether has to be a reasonable length for the animal’s size and space, and the collar cannot choke or pinch when the animal pulls against it.2Oregon Public Law. Oregon Code 167.343 – Unlawful Tethering Falling short of any of these standards can bring in law enforcement or animal control, and it is often the first step toward a neglect charge.
Cruelty, Neglect, and Abuse Charges
The criminal statutes are layered. Which charge applies turns on whether the animal was actively harmed or simply not cared for, whether serious injury or death resulted, and whether the defendant has prior convictions.
Neglect
Animal neglect in the second degree is a Class B misdemeanor and the usual starting charge. It covers failing to provide minimum care, or tethering a domestic animal in a way that causes physical injury. Physical harm is not required to prove the failure-to-provide-care version. The charge steps up to a Class C felony if the defendant has two or more prior neglect convictions, the offense involves eleven or more animals, or it is committed in front of a child and the defendant has a domestic violence history.3Oregon Public Law. Oregon Code 167.325 – Animal Neglect in the Second Degree
First-degree neglect is a Class A misdemeanor and applies when the failure to provide care, or improper tethering, results in serious physical injury or death.4Oregon Public Law. Oregon Code 167.330 – Animal Neglect in the First Degree Serious physical injury is defined as injury creating a substantial risk of death, or causing lasting disfigurement or loss of organ function.1Oregon Public Law. Oregon Code 167.310 – Definitions for ORS 167.310 to 167.351 First-degree neglect also escalates to a Class C felony with prior convictions, ten or more animals involved, or commission in front of a child.
Abuse
Animal abuse in the second degree is a Class B misdemeanor covering the reckless or intentional infliction of physical injury on an animal.5Oregon Public Law. Oregon Code 167.315 – Animal Abuse in the Second Degree First-degree abuse is a Class A misdemeanor and applies when someone causes serious physical injury or cruelly causes the animal’s death. It becomes a Class C felony with prior abuse or domestic violence convictions, or if committed in a child’s presence.6Oregon Public Law. Oregon Code 167.320 – Animal Abuse in the First Degree
The most serious charge is aggravated animal abuse in the first degree, a Class C felony from the start. It applies when a person maliciously kills an animal or intentionally tortures one. “Maliciously” means acting with a depravity of mind and reckless disregard for life; “torture” means an action whose primary purpose is to inflict pain.7Oregon Public Law. Oregon Code 167.322 – Aggravated Animal Abuse in the First Degree A Class C felony carries up to five years in prison.8Oregon Public Law. Oregon Code 161.605 – Maximum Terms of Imprisonment for Felonies
Abandonment
Leaving a domestic animal or horse at any location without arranging for minimum care is animal abandonment, a Class B misdemeanor.9Oregon State Legislature. Oregon Code 167.340 – Animal Abandonment Dropping the animal near a shelter or vet clinic is not a defense unless you actually coordinated care with that facility beforehand.
Dog Bite Liability
Oregon holds dog owners strictly liable for the economic damages their dog causes when it injures someone. Under ORS 31.360, a bite victim does not have to prove the owner knew the dog was dangerous or should have seen an attack coming. If the dog bites, the owner owes the medical bills regardless of the dog’s history. The owner can still raise defenses, most importantly that the victim provoked the dog.10Oregon Public Law. Oregon Code 31.360 – Proof Required for Claim of Economic Damages
A separate rule kicks in once a court has classified a dog as “potentially dangerous.” After that designation, the keeper faces strict liability for all economic damages from any later injury the dog causes, unless the injured person was provoking the dog, assaulting the owner, or trespassing.11Oregon Public Law. Oregon Code 609.115 – Liability for Injury or Property Damage Caused by Potentially Dangerous Dog The designation creates a documented record of risk, so an owner has a much harder time arguing the next incident was unforeseeable.
Dangerous Dogs and Nuisance Dogs
A dog is classified as “dangerous” if it causes serious physical injury or kills someone without provocation, repeats potentially dangerous behavior after the owner has already been found in violation of nuisance rules, or is used as a weapon during a crime.12Oregon Public Law. Oregon Code 609.098 – Maintaining Dangerous Dog Owners who negligently fail to prevent those acts face criminal charges for maintaining a dangerous dog, and courts can order the animal seized and euthanized.
Short of a bite, a dog counts as a public nuisance if it chases people or vehicles off its owner’s property, damages other people’s property, or disturbs neighbors with frequent or prolonged noise.13Oregon Public Law. Oregon Code 609.095 – Dog as Public Nuisance Maintaining a nuisance dog is a Class B violation, with a maximum fine of $1,000.14Oregon Public Law. Oregon Code 153.018 – Maximum Fines
Rabies Vaccination
All dogs must be vaccinated against rabies by six months of age. The shot has to be given by a licensed veterinarian, who issues a certificate recording the dog’s description, the vaccine type and lot number, the vaccination date, and the revaccination due date.15Legal Information Institute. Oregon Administrative Code 333-019-0017 – Rabies Vaccination for Animals Counties license dogs separately and generally require proof of current vaccination before issuing a license, with lower fees for spayed or neutered animals.
Rescuing an Animal From a Hot Car
Oregon shields bystanders from criminal and civil liability for breaking into a vehicle to save a distressed animal, but only if they meet all five conditions in ORS 30.813:16Oregon Public Law. Oregon Code 30.813 – Liability of Person Who Enters Motor Vehicle
- Confirm the vehicle is locked or the animal otherwise cannot get out.
- Reasonably believe the animal will suffer harm if left inside.
- Call law enforcement or emergency services before entering, or as soon as reasonably possible after.
- Use no more force than necessary to open the vehicle and remove the animal.
- Stay with the animal until law enforcement, emergency responders, or the vehicle’s owner arrives.
The immunity does not cover gross negligence or reckless behavior. Smashing a window when an unlocked door is available, or leaving the scene immediately after, will strip the protection.
Service and Assistance Animals
Under ORS 659A.143, places of public accommodation and state government programs cannot ask about the nature of a person’s disability, demand documentation that an animal is a trained assistance animal, or charge extra fees because of the animal.17Oregon Public Law. Oregon Code 659A.143 – Assistance Animals The only grounds for removing the animal are that it is not housebroken, or it is out of control and the handler is not taking effective action. Even then, the person still has to be allowed to access the goods and services without the animal.
Housing is a separate question, and the ground has shifted. In May 2026 the U.S. Department of Housing and Urban Development announced it would no longer pursue fair housing complaints on behalf of tenants whose emotional support animals have not been individually trained to perform specific tasks. Landlords are not required, under the new federal guidance, to waive no-pets policies for untrained ESAs. Oregon state law may still offer broader protection, but the terrain is unsettled. A tenant relying on an untrained ESA for a housing accommodation should talk to a disability rights attorney about how Oregon’s own fair housing statutes apply.
Exotic Animals and Native Wildlife
Oregon bans private ownership of several categories of exotic animals: non-indigenous cats other than domestic cats, nonhuman primates, non-indigenous non-wolf canids other than domestic dogs, bears other than black bears, and crocodilians.18Oregon State Legislature. Oregon Code 609.305 – Exotic Animal Defined Wolves fall outside the exotic definition because gray wolves are native to Oregon and are covered by separate wildlife rules.
No new private exotic animal permits have been issued since January 1, 2010. Anyone who kept an exotic animal under a pre-2010 permit may continue to do so, but breeding is prohibited except in narrow circumstances involving small exotic cats.19Oregon State Legislature. Oregon Code 609 – Dogs, Exotic Animals, Dealers Keeping an exotic animal without a valid permit is a Class B misdemeanor, and a court can order the animal forfeited to a sanctuary or agency and require the defendant to repay the cost of care.20Oregon Public Law. Oregon Code 609.992 – Penalties for ORS 609.341
Native wildlife is regulated separately. Oregon prohibits removing native wildlife from its habitat or holding it in captivity without authorization from the Department of Fish and Wildlife.21Oregon Public Law. Oregon Code 497.308 – Wildlife Holding and Habitat Removal Permits That covers deer, raccoons, birds of prey, and other animals people sometimes try to raise after finding them injured or apparently orphaned. Picking up a baby animal and taking it home is a Class A misdemeanor, punishable by up to one year in jail and a $6,250 fine.22Oregon Department of Fish and Wildlife. Leave Young Wildlife in the Wild If you find a wild animal that needs help, call ODFW or a licensed wildlife rehabilitator rather than trying to care for it yourself.
Livestock Fencing: Open Range vs. Livestock Districts
Whether you have to keep livestock in or keep livestock out depends on where your land is. Oregon divides the state into livestock districts, where animals may not roam freely, and open range, where they may.23Oregon Public Law. Oregon Code 607.005 – Definitions
In a livestock district, the owner has to build and maintain fences adequate to contain the animals. If stock escape and damage a neighbor’s crops or property, the owner is liable. In open range, the burden flips: a landowner who wants to keep wandering cattle or sheep off their fields is responsible for fencing them out. This catches newcomers off guard, particularly people who buy rural property near open range without realizing the neighbor’s cows are legally entitled to be there.
Livestock found on public highways or in prohibited areas can be impounded by the county sheriff or a brand inspector. Recovering them means paying daily boarding fees and administrative costs, and repeated failures to maintain legal fencing can lead to civil lawsuits for crop damage and lost agricultural revenue.
