How liability works in Ohio

What the rule is, and what you must show.

What the victim must show
Liability attaches unless the victim was trespassing or committing a crime, or was teasing, tormenting, or abusing the dog on the owner’s property. It reaches any injury, not just bites.

Landlords & defenses

Who else can be liable, and what defeats a claim.

Landlord liability
Conditional — only if the landlord is a "harborer" (housing or controlling the dog) or the attack was in a common area the landlord controls. Ohio has narrowed "harborer" so a property owner who merely allows a tenant’s dog is not strictly liable.
Main defenses
Criminal trespass / other crimeTeasing, tormenting, or abusing the dog (provocation)

Recent developments

Avery’s Law (HB 247) (effective 2026-03-18) — overlay only, the liability type did not change: Avery’s Law adds a tiered dangerous/vicious classification system, mandatory liability insurance (minimum $100,000) for vicious/dangerous dogs, and authority for a dog warden to seize a dog immediately after a serious attack. It strengthens criminal enforcement and public safety — it does NOT change the civil standard. Ohio remains strict liability under §955.28(B); do not read Avery’s Law as a flip to one-bite.

What Ohio dog-bite victims get wrong

Ohio is a broad strict-liability state: under R.C. §955.28(B) the owner, keeper, or harborer is liable for any injury a dog causes — bite or not — unless the victim was trespassing, committing a crime, or tormenting the dog. The headline you may have seen is Avery’s Law (HB 247), effective March 18, 2026, and it is important to read it correctly: it adds a tiered dangerous-dog classification, mandatory liability insurance of at least $100,000 for vicious or dangerous dogs, and immediate-seizure authority for dog wardens. What it does not do is change the civil standard — Ohio is still strict liability. Anyone telling you Avery’s Law turned Ohio into a "one-bite" state has it backwards. On landlords, Ohio has narrowed "harborer," so simply allowing a tenant’s dog is not enough.

Common questions

Is Ohio a strict-liability dog-bite state?

Yes. Under R.C. §955.28(B) the owner, keeper, or harborer is strictly liable for any injury a dog causes, without proof of prior viciousness or the owner’s knowledge.

Did Avery’s Law change Ohio from strict liability to one-bite?

No. Avery’s Law (effective March 18, 2026) adds a dangerous-dog classification, mandatory $100,000 insurance, and seizure authority — but Ohio remains strict liability under §955.28(B). The civil standard did not change.

Does Ohio’s dog-bite law cover injuries other than bites?

Yes. Section 955.28(B) reaches any injury a dog causes, so being knocked down or otherwise hurt can qualify, not just a bite.

Is a landlord liable for a tenant’s dog in Ohio?

Only if the landlord is a "harborer" or the attack was in a controlled common area. Ohio has narrowed "harborer," so merely allowing a tenant’s dog is not enough for strict liability.
