Ohio Dog Bite Laws: Liability and Victim Rights

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:

Category	Definition
Owner	The person who legally possesses or claims ownership of the dog, typically the individual whose name appears on licensing or veterinary records
Keeper	A person who had or was supposed to have physical control over the dog at the time of the incident, such as a dog walker, pet sitter, or friend temporarily caring for the animal
Harborer	A person who has possession and control over the premises where the dog lives and silently acquiesces to the dog's presence

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 based on their behavior under ORC § 955.11. These classifications carry serious consequences for owners.

Nuisance Dog

A nuisance dog is one that, without provocation and while off the premises of its owner, keeper, or harborer, has chased or approached a person in a menacing fashion or an apparent attitude of attack, or has attempted to bite or otherwise endanger any person.

Dangerous Dog

A dangerous dog is one that, without provocation, has caused injury (other than killing or serious injury) to any person, or has been the subject of a third or subsequent violation of confinement requirements.

Vicious Dog

A vicious dog is one that, without provocation, has killed or caused serious injury to any person. Police dogs acting in the line of duty are excluded from this definition. Dogs that injured someone who was committing a criminal offense on the owner's property are also excluded.

Requirements for Owners of Dangerous and Vicious Dogs

Owners of dogs with a dangerous or vicious designation must comply with strict requirements under ORC § 955.22:

• Maintain at least $100,000 in liability insurance
• Keep the dog in a locked, secure enclosure on the owner's property
• Use a muzzle and a leash no longer than six feet when the dog is off the owner's property
• Post clearly visible warning signs on the property
• Microchip the dog for permanent identification
• Pay a $100 annual registration fee for a dangerous or vicious dog

Failing to comply with these requirements is a criminal offense that can result in fines and potential jail time.

Avery's Law: Major Changes Effective March 2026

Governor DeWine signed House Bill 247, known as Avery's Law, on December 19, 2025. The law takes effect in March 2026 and significantly strengthens Ohio's dangerous dog framework.

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. Owners who negligently fail to prevent an unprovoked attack by a dog already classified as nuisance, dangerous, or vicious now face criminal charges:

Dog Classification	Charge Level
Dangerous dog attack	Fourth-degree misdemeanor
Vicious dog attack	Fourth-degree felony with a minimum of six months in jail
Repeat vicious dog offense	Felony punishable by up to $10,000 fine and three years in prison

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 ORC § 955.22, dogs must be kept under reasonable control at all times. Ohio does not have a single statewide leash law, but the statute 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 in certain circumstances. The Ohio Supreme Court has considered this issue in recent cases, including Hipshire v. Oakwood Village (Case No. 2025-0175), which examined whether a manufactured housing complex owner qualifies as a harborer.

Under current Ohio law, a landlord may be considered a harborer if:

• The landlord possesses and controls common areas where the dog was present
• The landlord permitted or acquiesced in the tenant keeping the dog in shared spaces
• The landlord had some level of control over where the dog was kept

A landlord who simply rents property to a tenant who owns a dog is not automatically liable. The key question is whether the landlord exercised control over the premises where the bite occurred and knowingly allowed the dog's presence there.

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 § 955.22, failing to confine or control a dangerous or vicious dog is a criminal offense. The severity depends on the circumstances:

• Failing to confine a dangerous dog: up to a fourth-degree misdemeanor
• Failing to confine a vicious dog: up to a first-degree misdemeanor
• A vicious dog that causes injury while unconfined: may result in felony charges

Penalties Under Avery's Law (Effective March 2026)

As noted above, Avery's Law introduces new criminal penalties for owners who negligently fail to prevent attacks by dogs already classified as dangerous or vicious. These range from fourth-degree misdemeanors to fourth-degree felonies depending on the dog's classification and the severity of the attack.

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.
