The state-level rules every owner and walker in Indiana should know. Local leash lengths, licensing and off-leash rules are set by each city — find those on the city pages below.
Indiana runs on the one-bite rule and negligence, with a narrow strict-liability carve-out — and its legal definition of "owner" includes anyone who keeps or harbors a dog.
Indiana does not impose blanket strict liability. Strict liability (IC 15-20-1-3) applies only in a narrow situation: a dog, without provocation, bites someone acting peaceably while performing a duty required by state law, federal law, or postal regulations — the classic case being a postal worker, meter reader, or code inspector. For those victims the owner is liable regardless of the dog's history.
Everyone else proceeds under the one-bite rule and negligence: the victim must prove the owner knew or should have known of the dog's dangerous propensity, or that the owner was negligent (broke a leash law, left a gate open, failed to repair a fence). Crucially, Indiana's definition of owner is broad (IC 15-20-1-2) — it includes anyone who possesses, keeps, or harbors the dog, so dog-sitters, walkers, and temporary keepers can carry the same liability as the legal owner.
Under IC 15-20-1-4, recklessly, knowingly, or intentionally failing to restrain a dog that then leaves the property and bites someone without provocation is a misdemeanor — escalating with priors or severity, up to a Level 6 felony if the attack causes death.
Leash and restraint rules are set by local ordinance (city or county) — there is no statewide leash law, and violating a local leash ordinance is strong evidence of negligence in a bite claim. Indiana follows modified comparative fault: a victim's recovery is reduced by their share of blame and barred entirely if they are 51% or more at fault. The personal-injury limit is two years.
Wolf hybrids and coydogs are regulated and restricted (IC 15-20-1-5), with secure-enclosure requirements and criminal penalties for non-compliance.
