Ohio Dog Bite Laws: Liability and Victim Rights

Ohio imposes strict liability on the owner, keeper, or harborer of a dog for any injury, death, or property damage the animal causes under Ohio Rev. Code 955.28. Victims do not need to prove negligence or a prior bite to recover compensation.

How Ohio Dog Bite Liability Works

Ohio is a strict liability state for dog bites. Under ORC § 955.28(B), the owner, keeper, or harborer of a dog is liable for any injury, death, or loss to a person or property caused by the dog. The victim does not need to prove the owner was negligent or that the dog had bitten anyone before.

This means that if a dog bites you while you are lawfully present on someone's property or in a public place, the person responsible for the dog owes you compensation. Ohio's strict liability approach is one of the strongest victim protections of any state.

Who Can Be Held Liable

Liability under ORC § 955.28(B) extends beyond the dog's legal owner. Ohio law holds three categories of people responsible:

This three-part framework means that multiple people can share liability for a single dog bite incident. For example, if a dog bites someone while being watched by a neighbor at the neighbor's home, both the owner and the neighbor (as keeper or harborer) could be liable.

What the Victim Must Prove

Because Ohio applies strict liability, the victim's burden of proof is relatively straightforward. The victim must show:

• The defendant was the owner, keeper, or harborer of the dog
• The dog caused injury, death, or property damage
• The victim was in a place where they had a legal right to be

The victim does not need to prove the owner was careless, that the dog had a history of aggression, or that the owner knew the dog was dangerous.

Exceptions to Strict Liability

Ohio's strict liability statute includes specific exceptions. The owner, keeper, or harborer is not liable if, at the time of the injury, the victim was:

• Committing or attempting to commit criminal trespass or another criminal offense (other than a minor misdemeanor) on the property of the owner, keeper, or harborer
• Committing or attempting to commit a criminal offense other than a minor misdemeanor against any person
• Teasing, tormenting, or abusing the dog on the owner's, keeper's, or harborer's property

These exceptions are narrowly defined. The trespassing defense, for instance, requires that the victim was actually committing a criminal offense, not simply that they were uninvited. A delivery driver, mail carrier, or door-to-door salesperson who enters a property to conduct lawful business is protected under the statute.

Comparative Fault in Ohio Dog Bite Cases

Even in a strict liability state, Ohio applies comparative fault principles under ORC § 2315.33. This means a victim's compensation can be reduced if they were partially at fault for the incident.

Ohio follows a modified comparative negligence system with a 51% bar:

• If the victim is 50% or less at fault, the victim can still recover damages, but the award is reduced by the victim's percentage of fault
• If the victim is 51% or more at fault, the victim is completely barred from recovery

For example, if a jury finds that a victim suffered $80,000 in damages but was 20% at fault for approaching the dog despite warning signs, the victim would recover $64,000.

Common actions that can increase a victim's share of fault include ignoring posted warning signs, interacting with a visibly agitated dog, or reaching into a fenced area.

Dangerous and Vicious Dog Classifications

Ohio law classifies dogs by their behavior, and the classification attaches only through a formal process. Under ORC § 955.01, a dog is a nuisance dog, dangerous dog, or vicious dog only if it has been designated as such under ORC § 955.23, or if a court determines that the dog previously engaged in the corresponding act. The underlying acts are defined in ORC § 955.22(A).

A dog warden or other authorized person who has probable cause to believe a dog committed one of these acts may designate the dog and must then notify the owner, keeper, or harborer by certified mail or in person. The owner has ten calendar days to request a court hearing. The court must hold that hearing within ten days and decide, by clear and convincing evidence, whether the dog committed the act.

Nuisance Dog Act

A nuisance dog act is committed when a dog, without provocation and while off the premises of its owner, keeper, or harborer, chases or approaches a person in a menacing fashion or an apparent attitude of attack, attempts to bite or otherwise endanger a person, causes injury to a person without making physical contact, chases, threatens, harasses, or injures another dog or livestock, or has been the subject of a third or subsequent violation of ORC § 955.21.

Dangerous Dog Act

A dangerous dog act is committed when a dog, without provocation, causes injury to a person by physical contact (other than killing or serious injury) in a menacing fashion or an apparent attitude of attack, causes serious injury to a person without making physical contact in a menacing fashion or an apparent attitude of attack, kills another dog, or causes serious injury to another dog that results in that dog being euthanized.

Vicious Dog Act

A vicious dog act is committed when a dog, without provocation, kills a person, causes serious injury to a person by physical contact, or engages in a dangerous dog act after having already been designated a dangerous dog under ORC § 955.23. Police dogs being used to assist law enforcement officers in the performance of their official duties are excluded from all three definitions.

Under ORC § 955.22(A)(6), whether a dog acted "without provocation" turns on whether the dog was teased, tormented, or abused by a person, whether it was coming to the aid or defense of a person who was not engaged in illegal or criminal activity, and whether it was attacked by another dog or livestock.

Requirements for Owners of Dangerous and Vicious Dogs

Owners of dogs with a dangerous or vicious designation must comply with strict requirements under ORC § 955.24 (confinement and insurance) and ORC § 955.02 (registration):

• Maintain at least $100,000 in liability insurance and provide proof of it on request to a law enforcement officer, dog warden, or public health official (ORC § 955.24(B)(1) and (2))
• While the dog is outdoors on the owner's property, securely confine it in a locked pen with a top, a locked fenced yard built to prevent escape, or another locked enclosure with a top (ORC § 955.24(A)(1))
• While the dog is off the owner's property, keep it on a chain-link leash or tether no longer than six feet and additionally do at least one of the following: keep it in a locked topped enclosure, have the leash controlled by a person of suitable age and discretion (or securely anchored with such a person stationed close enough to prevent injury), or muzzle the dog (ORC § 955.24(A)(3))
• Notify the local dog warden immediately if the dog is loose or unconfined, bites a person, or attacks another animal while off the owner's property (ORC § 955.24(B)(3))
• Apply to the county auditor for a dangerous dog registration and pay a $100 fee, renewed annually (ORC § 955.02(D))
• Post and continue to post clearly visible signs at the residence warning both minors and adults of the presence of a dangerous dog (ORC § 955.02(D))
• Have the dog permanently identified by a microchip and supply the microchip number with the registration (ORC § 955.02(D))

A muzzle is one of three ways to satisfy the off-premises requirement, not a standing obligation on top of the leash. Failing to comply with these requirements is a criminal offense that can result in fines and potential jail time, and the penalties are set out below.

Avery's Law: Major Changes in Effect Since March 2026

Governor DeWine signed House Bill 247, known as Avery's Law, on December 19, 2025. The law took effect on March 20, 2026, and significantly strengthened Ohio's dangerous dog framework. It is the law now in force.

Avery's Law also renumbered much of Chapter 955, so older sources still cite sections that have moved. The owner-duty section formerly numbered 955.22 is now ORC § 955.24, the designation procedures formerly at 955.222 are now ORC § 955.23, the chapter definitions of nuisance, dangerous, and vicious dog now appear in ORC § 955.01, and a new ORC § 955.22 sets out the nuisance, dangerous, and vicious dog acts along with the criminal offenses for failing to prevent them. ORC § 955.28, the strict liability statute this page is built around, was not renumbered.

Avery's Law is named after Avery Russell, an 11-year-old girl who was severely injured in a dog attack in Reynoldsburg, Ohio, in June 2024. The legislation passed the Ohio House in June 2025 and received unanimous Senate approval in November 2025.

Key Provisions of Avery's Law

Mandatory euthanasia for the most serious attacks. If a dog kills or causes serious injury to a person in an unprovoked attack, the court must now order the dog's humane euthanasia. Previously, Ohio law only mandated euthanasia after a dog killed a second person. An exception applies if the serious injury occurred during playful, nonaggressive, or age-appropriate behavior.

Criminal penalties for negligent owners. ORC § 955.22 makes it an offense for an owner, keeper, or harborer to negligently fail to prevent a dog from committing a nuisance, dangerous, or vicious dog act. The charge depends on the act and on whether the dog had already been designated dangerous or vicious:

An animal shelter for dogs that keeps or harbors the dog is held to a recklessness standard rather than negligence for these offenses.

Immediate seizure authority. Local dog wardens can now seize a dog immediately after an attack, eliminating the procedural delays that previously hampered enforcement.

Ownership restrictions for convicted offenders. A person convicted of a felony violent dog attack offense cannot own or reside with unspayed or unneutered dogs older than 12 weeks, any dog classified as dangerous or vicious, or any dog that lacks a microchip.

Dog Owner Responsibilities

Beyond the rules for dangerous and vicious dogs, all Ohio dog owners must follow general requirements.

Licensing and Registration

All dogs over three months old must be registered with the county auditor. Registration must be renewed annually. The county issues a dog tag that must be attached to the dog's collar.

Rabies Vaccination

Ohio law requires all dogs to be vaccinated against rabies. After a bite, the dog must be quarantined for observation, typically for 10 days.

Confinement and Leash Laws

Under Ohio Revised Code Chapter 955, dogs must be kept under reasonable control at all times. Ohio does not have a single statewide leash law, but state law requires that dogs be confined to the owner's property or kept under the owner's control. Most Ohio municipalities enforce their own leash ordinances in public areas.

Victim Rights and Recoverable Damages

Dog bite victims in Ohio can recover a broad range of damages through a civil lawsuit or insurance claim.

Economic Damages

• Medical expenses, including emergency care, surgery, hospitalization, and rehabilitation
• Future medical costs for ongoing treatment, reconstructive surgery, or therapy
• Lost wages during recovery
• Lost earning capacity if injuries cause long-term disability
• Property damage, such as destroyed clothing or personal items

Non-Economic Damages

• Pain and suffering
• Emotional distress and psychological trauma, including PTSD and anxiety around dogs
• Scarring and permanent disfigurement
• Loss of enjoyment of life

Because Ohio applies strict liability, victims can recover both economic and non-economic damages without needing to prove the owner was at fault. The only limits on recovery come from the statutory exceptions or comparative fault reductions.

Statute of Limitations

The deadline for filing a dog bite lawsuit in Ohio depends on the legal theory:

• Bodily injury claims under ORC § 2305.10 must be filed within two years from the date of the bite
• Strict liability claims filed directly under ORC § 955.28 may be subject to a longer filing period, as some Ohio courts have applied a six-year window for statutory claims

Important exceptions to the deadline include:

• Minors: The statute of limitations may be tolled (paused) until the child turns 18, at which point the filing clock begins
• Mental incapacity: If the victim is mentally incapacitated at the time of the bite, the filing deadline may be paused until competency is restored
• Government entity claims: Claims against a city, county, or state government entity often require earlier notice and shorter filing deadlines

Filing after the deadline almost always results in the court dismissing the case. Victims should consult an attorney promptly after a dog bite to preserve all legal options.

Landlord Liability for Dog Bites

Landlords in Ohio can be held liable as a "harborer" under ORC § 955.28 only in narrow circumstances. On June 17, 2026, the Ohio Supreme Court decided L.H. v. Sun Secured Financing, L.L.C. (Slip Opinion No. 2026-Ohio-2219, Case No. 2025-0175), the appeal previously argued as Hipshire v. Oakwood Village, and for the first time defined "harborer" under R.C. 955.28(B): a person harbors a dog only if they shelter, protect, or exercise control over the dog itself.

Under this 5-2 decision, controlling the premises is not enough. A property owner is a harborer only by sheltering, protecting, or exercising control over the dog itself. The Court held that:

• Allowing residents or tenants to keep dogs in their own dwellings is not, by itself, harboring
• Permitting a dog to be in common areas while on a leash is not, by itself, harboring
• A property owner harbors a dog only by sheltering, protecting, or exercising control over the dog itself

A landlord who simply rents property to a tenant who owns a dog, or who allows leashed dogs in shared areas, is not automatically liable. After L.H. v. Sun Secured Financing, the key question is whether the landlord sheltered, protected, or exercised control over the dog itself, not merely over the premises where the bite occurred. This ruling narrows landlord and property-owner liability for a tenant's dog in Ohio.

Landlords should consider including clear pet policies in lease agreements, requiring tenants with dogs to carry renter's insurance with liability coverage, and acting promptly when they learn a tenant's dog has shown aggressive behavior.

Breed-Specific Legislation in Ohio

Ohio repealed its statewide breed-specific legislation in 2012 when Governor Kasich signed House Bill 14 into law. Before HB 14, Ohio was the only state with a statewide law that automatically classified all pit bull-type dogs as "vicious," regardless of the individual dog's behavior.

HB 14 replaced the breed-based classification with a behavior-based system. Under the current law, any dog of any breed can be designated as nuisance, dangerous, or vicious based on its individual actions, not its breed.

However, HB 14 did not preempt local ordinances. Some Ohio municipalities still enforce their own breed-specific restrictions:

• Lakewood maintains restrictions on pit bull-type dogs
• Warrensville Heights bans pit bulls
• Garfield Heights enforces breed-specific rules

The trend across Ohio municipalities has shifted toward behavior-based dangerous dog ordinances that apply to all breeds equally. Residents should check their local ordinances for any breed-specific rules that may apply in their community.

Criminal Penalties for Dog Owners

Ohio imposes criminal penalties on dog owners in several situations, particularly when a dog causes injury due to the owner's negligence or failure to comply with dangerous dog requirements.

Violations of Confinement and Control Requirements

Under ORC § 955.24(A), the owner, keeper, or harborer of a dog designated dangerous or vicious must confine and restrain the dog as described above. A violation is a strict liability offense, and ORC § 955.24(F)(1) sets a single penalty that does not vary between dangerous and vicious dogs:

• First offense: fourth-degree misdemeanor
• Each subsequent offense: third-degree misdemeanor

In addition, the court may order the owner to personally supervise the dog, to have the dog complete obedience training, or both. In the alternative, the court may order the dog humanely destroyed by a licensed veterinarian or the county dog warden at the owner's expense.

Failing to carry the required liability insurance under ORC § 955.24(B)(1) is a separate offense: a minor misdemeanor on a first offense and a fourth-degree misdemeanor on each subsequent offense.

Penalties for Failing to Prevent a Dog Act

As noted above, ORC § 955.22 sets criminal penalties for owners who negligently fail to prevent a nuisance, dangerous, or vicious dog act. These range from a minor misdemeanor up to a third-degree felony, which applies where a dog already designated dangerous or vicious commits a vicious dog act that injures or kills a person.

Intentional Use of a Dog as a Weapon

If an owner intentionally uses a dog to attack or injure another person, the owner can face felony assault charges in addition to any dog-specific penalties.

How to File a Dog Bite Claim in Ohio

If a dog bites you in Ohio, take these steps to protect your legal rights:

• Get medical treatment immediately. Keep all medical records, bills, and receipts. Dog bites carry a risk of infection, nerve damage, and scarring that may require ongoing care.
• Report the bite to local animal control and your local health department. Ohio law requires reporting of dog bites for rabies monitoring.
• Document everything. Photograph your injuries, the location of the attack, and the dog if you can do so safely.
• Collect witness information. Get names and contact details of anyone who saw the bite occur.
• Identify the responsible parties. Obtain the dog owner's name, address, and homeowner's or renter's insurance information. Remember that keepers and harborers may also be liable.
• Preserve physical evidence. Keep torn or bloodied clothing and any other items damaged in the attack.
• Consult a personal injury attorney. Ohio's strict liability statute gives bite victims strong legal standing, but an attorney can help identify all liable parties and navigate comparative fault issues.
