Dog Bite Laws in Iowa
Whether Iowa 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 Iowa
What the rule is, and what you must show.
Landlords & defenses
Who else can be liable, and what defeats a claim.
Iowa’s "unlawful act" defense is narrow: the victim’s illegal act must directly contribute to the injury, so ordinary carelessness by the victim does not defeat the claim. A separate exception covers a dog with rabies unless the owner had reason to know and could have prevented the harm.

| Liability model | Strict liability |
| Basis | Statute — Iowa Code §351.28 |
| What it covers | The dog was attacking or attempting to bite a person (or was caught worrying, maiming, or killing a domestic animal), and you were not doing an unlawful act that directly contributed to the injury. |
| Landlord | Generally no. Section 351.28 fixes liability on the dog’s owner, not a landlord. A landlord can be reached only through ordinary common-law negligence, which requires actual knowledge that the tenant’s dog was dangerous plus the ability to remove it. |
| Main defenses | Victim doing an unlawful act · Not the owner · Rabies exception (no knowledge) |
What Iowa dog-bite victims get wrong
Iowa is a strict-liability state, but its statute is written more broadly than the classic "bite" laws. Under Iowa Code §351.28 the owner is liable for all damages the dog does while it is attacking or attempting to bite a person, so a lunge or attack that causes injury short of a completed bite can still count. You do not have to prove the owner knew the dog was dangerous. The statute carries two built-in limits. First, there is no recovery when the injured person was doing an unlawful act that directly contributed to the injury. Second, if the dog had rabies, the owner escapes liability unless they had reason to know and could have prevented the harm. Landlords sit outside §351.28 and can be reached only through ordinary negligence.
Common questions
Is Iowa a strict-liability state for dog bites?
Yes. Under Iowa Code §351.28 the owner is liable for all damages the dog does while attacking or attempting to bite a person, regardless of whether the owner knew the dog was dangerous.
Does Iowa’s dog-bite law cover more than an actual bite?
Yes. The statute reaches damage the dog does while "attacking or attempting to bite" a person, so an attack that injures you without a completed bite can still be covered, unlike bite-only statutes in some other states.
What is the "unlawful act" defense in an Iowa dog-bite case?
If the injured person was doing an unlawful act that directly contributed to the injury, §351.28 does not apply. The illegal act has to directly contribute, so minor carelessness by the victim is not enough to bar the claim.
Can I sue my landlord if a tenant’s dog bit me in Iowa?
Generally not under §351.28, which applies to the owner. You would have to show the landlord was negligent, meaning they actually knew the dog was dangerous and had the ability to remove it.
