Does Indiana Follow the One-Bite Rule?
Last updated: August 2026. Reviewed by the Dog Bite Laws legal team.
Partially. Indiana is a mixed state, and which rule applies depends entirely on who was bitten.
- If you were performing a duty imposed by law, such as a postal carrier, a meter reader, a police officer, a firefighter, or a process server, Indiana Code section 15-20-1-3 imposes strict liability. The dog’s history is irrelevant.
- If you are anyone else, such as a neighbor, a guest, a child, or a passerby, Indiana applies the common-law one-bite rule. You must prove the owner knew or should have known the dog was dangerous.
Because most bite victims fall into the second category, Indiana functions as a one-bite state for the majority of claims.
| Rule | Mixed / limited (depends on the victim) |
|---|---|
| Governing law | Ind. Code § 15-20-1-3, plus common law |
| What the victim must prove | Depends on who you are. Performing a duty imposed by law, such as a postal carrier: nothing about the dog. Everyone else: that the owner knew, or should have known, the dog was dangerous. |
| Does the dog’s past matter? | Yes for most victims. No for those performing a legal duty. |
| Covers injuries other than bites? | The statute addresses bites. Other injuries proceed in negligence. |
| Deadline to file | 2 years (modified comparative fault bars recovery above 50%) |

Which rule applies to you
| You were performing a duty imposed by law | You are anyone else | |
|---|---|---|
| Typical examples | Postal carrier, meter reader, police officer, firefighter, process server, building inspector | Neighbor, houseguest, child, customer, passerby, jogger |
| Rule that applies | Strict liability | One-bite rule |
| Must you prove the owner knew? | No. The dog’s history is irrelevant. | Yes. This is usually the whole case. |
| Governing law | Ind. Code § 15-20-1-3 | Indiana common law, plus ordinary negligence |
| Conditions | You were acting peaceably, were required to be there by law, and did not provoke the dog | You were lawfully present and did not provoke the dog |
This split is the single most important thing to establish early in an Indiana case, because it decides what you have to prove.
The statutory exception: Indiana Code section 15-20-1-3
Indiana’s statute is unusually narrow. It applies only where the victim was:
- Acting peaceably, and
- In a place they were required to be in order to discharge a duty imposed on them by law or by the United States Postal Service, and
- Not provoking the dog.
Where those conditions are met, the owner is liable regardless of whether the dog had ever shown aggression. The statute exists because people who cannot decline to approach a property, mail carriers above all, should not bear the risk of an unknown dog.
Everyone else: proving the owner knew
For a typical victim, Indiana requires proof that the owner had notice of the dog’s dangerous propensity. Evidence that commonly establishes it includes prior bites or attacks, complaints to animal control or the landlord, warning signage, muzzle or restraint use, veterinary notes about aggression, and testimony from neighbors or delivery drivers about earlier lunging or charging.
Indiana also permits an ordinary negligence claim, which does not depend on the dog’s history at all. An owner who violated a leash ordinance, left a gate open, or failed to restrain a dog around children can be liable on that theory even for a first incident. In practice, most Indiana dog bite cases plead both.
Criminal exposure for Indiana dog owners
Separately from any civil claim, Indiana Code section 15-20-1-4 makes it a Class C misdemeanor for an owner to recklessly fail to restrain a dog that then bites someone, punishable by up to 60 days in jail and a $500 fine. The offense escalates to a Class B misdemeanor for a repeat violation, and to a felony where the attack causes serious bodily injury or death.
Deadline to file an Indiana dog bite claim
Indiana’s personal injury statute of limitations is two years from the date of injury under Indiana Code section 34-11-2-4. Indiana also applies modified comparative fault: a victim found more than 50% at fault recovers nothing, and any award is reduced by the victim’s share of fault. That makes provocation arguments consequential in Indiana even when they do not defeat the claim outright.
Frequently asked questions
Partially. Indiana applies the common-law one-bite rule to most victims, but Indiana Code section 15-20-1-3 imposes strict liability when the victim was performing a duty imposed by law, such as a postal carrier or police officer.
Both, depending on the victim. Strict liability applies to people carrying out a legal duty. Everyone else must prove the owner knew or should have known the dog was dangerous.
Not necessarily. You must prove the owner knew of the dog's dangerous propensity, which prior growling, lunging, complaints, or restraint measures can establish without any earlier bite. You can also bring a negligence claim that does not depend on the dog's history.
Yes. Indiana Code section 15-20-1-3 was written to cover people required to be on the property to discharge a duty imposed by law or by the U.S. Postal Service, provided they were acting peaceably and did not provoke the dog.
Yes. Recklessly failing to restrain a dog that then bites someone is a Class C misdemeanor under Indiana Code section 15-20-1-4, and the offense escalates for repeat violations or serious injury.
Two years from the date of injury under Indiana Code section 34-11-2-4.

Because Indiana’s rule depends on the victim’s status and on what the owner knew, the early evidence, including animal control history, prior complaints, and veterinary notes, often decides the case. Those records are also the first to disappear.
