Dog Bite Laws in Indiana
Whether Indiana holds a dog owner automatically liable, follows the one-bite rule, or takes a mixed approach, plus landlord liability and the main defenses.
How liability works in Indiana
A hybrid: the two prongs below apply differently.
Under Ind. Code §15-20-1-3, if a dog bites you without provocation while you are acting peaceably somewhere you must be to discharge a duty imposed by state law, federal law, or postal regulations, the owner is strictly liable even if the dog had never behaved viciously and the owner had no knowledge of it.
Outside the duty-bound class, Indiana falls back on common law. You must show the owner knew or should have known of the dog’s dangerous propensity, or was otherwise negligent in keeping and controlling it (Ross v. Lowe).
This is a hybrid that splits by the dog’s legal status.
Landlords & defenses
Who else can be liable, and what defeats a claim.
The strict prong is narrow: an owner can defeat it by showing the victim provoked the dog, was not acting peaceably, or was not in a place required to discharge a legal or postal duty, which pushes the claim back into the harder common-law negligence prong.

| Liability model | Mixed / hybrid |
| Basis | Statute + common law — Ind. Code §15-20-1-3 (duty-bound victims) + negligence/scienter for everyone else |
| What it covers | For the strict prong: an unprovoked bite while you were acting peaceably in a place you had to be to discharge a duty under state law, federal law, or postal regulations. For the common-law prong: the owner knew or should have known of a dangerous propensity, or failed to use reasonable care in keeping and controlling the dog. |
| Landlord | Generally no. The §15-20-1-3 strict prong runs against the owner. A landlord is reached only through common-law negligence, which requires actual knowledge the tenant’s dog was dangerous plus the ability to remove it. |
| Main defenses | Provocation · Victim not acting peaceably · No duty / not in the covered class · No knowledge or negligence (common-law prong) · Trespassing |
What Indiana dog-bite victims get wrong
Indiana is a trap for anyone who wants a one-word answer. It is neither a clean strict-liability state nor a clean one-bite state; it is mixed, and the split turns on who got bitten. Indiana Code §15-20-1-3 makes an owner strictly liable when a dog bites, without provocation, a person who is acting peaceably and is somewhere they have to be to carry out a duty under state law, federal law, or postal regulations. That is the mail carrier, the meter reader, the process server. For that narrow group, prior viciousness and the owner’s knowledge do not matter. For everyone else, a social guest, a neighbor, most ordinary visitors, Indiana keeps the common-law rule: you have to prove the owner knew or should have known the dog was dangerous, or was otherwise negligent in keeping it (Ross v. Lowe). So the right question in Indiana is not "strict or one-bite," it is "which victim are you."
Common questions
Is Indiana a strict-liability or a one-bite state for dog bites?
Both, depending on the victim. Indiana Code §15-20-1-3 gives strict liability to people bitten while performing a legal or postal duty (like mail carriers). Everyone else must prove the owner’s knowledge or negligence under common law, so Indiana is a mixed state.
Who counts as a "duty-bound" victim under Indiana Code §15-20-1-3?
Someone acting peaceably in a place they had to be to discharge a duty imposed by Indiana law, federal law, or postal regulations. Mail carriers are the classic example, along with meter readers and officials on official business.
If a dog bites a house guest in Indiana, is the owner automatically liable?
No. A social guest is outside the §15-20-1-3 strict prong, so the guest must prove the owner knew or should have known the dog was dangerous, or was otherwise negligent in keeping and controlling it.
Does provocation defeat a strict-liability dog-bite claim in Indiana?
Yes. The §15-20-1-3 strict prong applies only to an unprovoked bite of someone acting peaceably. Provocation, or the victim not acting peaceably, takes the claim out of strict liability and back into the harder common-law prong.
