Strict Liability vs. the One-Bite Rule in Iowa

By the FigureMyTax Editorial Team · How we calculate

Iowa has held dog owners strictly liable since the 1870s — one of the oldest, most settled strict liability dog bite rules in the country, and a sharp contrast to any neighboring one-bite state.

A rule dating to 1873

Under Iowa Code §351.28, an owner is liable for all damages from a qualifying attack regardless of the dog's prior history or the owner's knowledge of any dangerous propensity. The core language traces back to the Iowa Code of 1873, making it one of the oldest continuously-applied strict liability dog bite statutes in the country.

Broader than a bite-specific statute

The statute covers a dog attacking or attempting to bite a person, as well as a dog caught worrying, maiming, or killing a domestic animal — a meaningfully wider scope than states whose strict liability statutes apply only to the bite itself.

No history required

A dog's first qualifying attack still triggers full owner liability — no prior incident needed. That's the defining difference from a true one-bite state, where a victim generally has to prove the owner knew or should have known about the dog's dangerous propensity before a first bite can support a claim.
