How Missouri Dog Bite Laws Protect Victims

Sansone & Lauber | August 22, 2025 | Dog Bites

If a dog has bitten you or someone you love in Missouri, you’re not powerless—and you don’t have to apologize for demanding full compensation. Missouri law is designed to protect victims, hold irresponsible dog owners accountable, and make insurance companies pay what’s owed.

Below, the dog bite lawyers at Sansone & Lauber breaks down exactly how these laws work, what compensation you can claim, the deadlines that apply, and the aggressive strategy we use to win.

Quick Takeaways

Missouri is a strict-liability state for dog bites. If a dog bites you without provocation while you’re in a public place or lawfully on private property, the owner (or possessor) is liable—period. Prior bites or “warning signs” aren’t required.
Comparative fault may reduce—but won’t erase—your recovery. If the defense argues you provoked the dog, your damages can be reduced by your percentage of fault, but you can still recover under Missouri’s pure comparative fault rule.
You usually have 5 years to file a dog-bite lawsuit in Missouri; for minors, the deadline is tolled until age 21 (often making the outer limit effectively age 26). Don’t wait—evidence disappears fast.
Report bites and follow quarantine rules. Missouri law requires reporting and enforcement of rabies/quarantine protocols—another source of crucial evidence.
Criminal and municipal penalties can apply to owners of “dangerous dogs,” separate from your civil claim for damages.

Missouri’s Strict-Liability Dog Bite Statute—Your Rights, Clearly

Missouri’s dog-bite statute is straightforward: when a dog bites without provocation, the owner or possessor is strictly liable for your injuries whether or not the dog ever showed vicious tendencies before and whether or not the owner “knew.” The law applies when you’re in public or lawfully on private property (including the owner’s property). Missouri Revisor of Statutes

Two other key points under the statute:

Comparative Fault Reduction. If the defense proves you share some fault (e.g., provoking the animal), your damages are reduced by that percentage—but your claim is not barred. That fits Missouri’s broader “pure comparative fault” system.
Additional Penalties. Courts can impose a fine up to $1,000 on the owner/possessor in dog-bite cases (a penalty separate from the civil compensation we’ll pursue for you).

Bottom line: In Missouri, you don’t have to prove the dog was “known dangerous.” You only need to prove (a) the dog bit you, (b) you were in a place you had a right to be, and (c) you didn’t provoke the attack. That’s the power of strict liability.

Pure Comparative Fault: How “Provocation” Arguments Really Work

Insurers love to allege “provocation” or “shared blame” to shrink your payout. Missouri is a pure comparative fault state: even if you were mostly at fault, you can still recover the remainder. For example, if a jury finds you 20% at fault on a $100,000 case, you still collect $80,000.

Missouri’s pure comparative-fault doctrine stems from Gustafson v. Benda (1983) and remains the standard. In short, shared fault reduces damages—it doesn’t wipe them out.

Who Can Be Held Liable Beyond the Dog’s Owner?

Owner or Possessor / Harborer. Liability attaches to people who own, possess, or harbor the dog. (Think: the person in control of the dog—not merely someone who’s present.)
Landlords? Rarely. Missouri courts generally do not hold a landlord liable unless the landlord is also an owner/possessor/harborer or exercised specific control over the animal and the area. These cases are tough and fact-intensive—but we know how to build them when the facts support it.
Employers. If a dog owned by an employee injures you within the scope of employment (e.g., a security animal), a vicarious liability theory may apply. We investigate employment relationships immediately.

“Lawfully on Private Property” — Delivery Drivers, Guests & Workers

The statute protects people bitten while lawfully on private property (think: invited guests, mail carriers, delivery drivers, contractors, utility workers). Trespassers have weaker claims, though each case turns on specific facts and evidence of notice/permission.

Dangerous Dogs & Criminal Exposure (Separate From Your Civil Case)

Missouri criminal law penalizes keeping a “dangerous dog,” especially after prior bite incidents. While these are criminal or municipal matters separate from your civil lawsuit, they can create helpful paper trails and admissions we use as leverage.

Reporting, Rabies & Quarantine: Why It Matters to Your Case

Missouri’s rabies-control and reporting statutes require agencies to be notified of bite incidents and authorize quarantine/isolation orders. Compliance records, health department notes, and animal control reports often become key evidence we pull early.

What Compensation Can a Missouri Dog Bite Victim Recover?

Every case is different, but we routinely pursue full-spectrum damages, including:

Emergency care, hospitalization & surgery (including plastic/reconstructive procedures)
Infection control (antibiotics, wound care), tetanus/rabies prophylaxis where indicated
Follow-up and scar revision; laser therapy; physical/occupational therapy
Psychological trauma (PTSD, phobias, anxiety); counseling
Lost income and diminished earning capacity
Out-of-pocket costs (medications, travel, childcare, bandages, compression garments)
Pain, suffering, disfigurement, and loss of normal life
Property damage (torn clothing, broken glasses/phones)
Punitive damages in egregious cases (e.g., reckless disregard)

Missouri’s statute also recognizes property/livestock damages caused by dogs—sometimes piggybacking on a bite claim.

The Deadline: Missouri Statute of Limitations for Dog Bite Claims

Adults: Generally 5 years from the date of injury to file a lawsuit. Don’t sit on your rights—witnesses disappear, dogs get relocated, and insurers shift tactics.
Minors: Missouri tolls the limitations period until age 21, then provides 5 additional years—often making the outside limit age 26. Specific facts and claim types can alter this; talk to us now.

Who Pays? (Hint: Usually Insurance)

In many cases, homeowners’ or renters’ insurance covers injuries caused by the policyholder’s dog (sometimes with breed or prior-bite exclusions). Umbrella coverage may also apply. If the bite happened at a business, there may be commercial coverage. We identify all collectible policies and stack coverage whenever possible.

On rental properties, we target the dog’s owner first (strict liability). We also examine whether a tenant or landlord exercised control over the animal or common areas—a nuanced, fact-heavy inquiry in Missouri.

What To Do Immediately After a Dog Bite (Step-by-Step)

Get urgent medical care. Bite wounds can seed deep infections. Follow your doctor’s orders and keep all records.
Report the bite to local animal control/health authorities and cooperate with quarantine protocols—this creates an official record we’ll use.
Identify the dog and owner. Names, addresses, phone numbers; photograph tags and the dog if safe.
Document everything. Photograph wounds immediately and over time; keep a pain and healing diary; save bloody clothing.
Collect witness info and any video (doorbell cams, neighbors’ phones).
Do not give recorded statements to insurers before speaking with us.

Insurance Pressure. We identify every applicable policy and apply leverage through well-documented demands and trial readiness.

Common Defense Tactics (and How We Counter Them)

“You Provoked the Dog.” We show your behavior was reasonable or that any contact wasn’t “provocation” under the circumstances; even if fault is shared, pure comparative fault limits the reduction.
“You Were Trespassing.” We establish that you were lawfully present (deliveries, invited guests, contractors, meter readers) or that the owner still violated duties.
“The Dog Never Bit Before.” Irrelevant under strict liability. We hammer the statute.
“It’s the Landlord’s Fault, Not Ours.” We pursue the owner/possessor first; landlord theories in Missouri are limited and fact-specific, which we’ll analyze aggressively.

FAQs: Missouri Dog Bite Claims

Does Missouri follow the “one-bite” rule?
No. Missouri has strict liability—you don’t need to show prior bites or known viciousness.

What if I was petting the dog?
If the defense proves “provocation,” your damages may be reduced, not eliminated, under pure comparative fault.

I’m a delivery driver. Am I protected?
Yes, if you’re lawfully on the property doing your job, the strict-liability statute applies.

Do I have to report the dog bite?
Reporting triggers health department and animal control protocols (rabies/quarantine) and creates documents we use as evidence. Follow local authority instructions.

How long do I have to sue?
Usually 5 years from the date of injury. Minors often have until age 26 under Missouri’s tolling rules. Don’t wait.

Can a landlord be liable?
Generally no, unless the landlord is also an owner/harborer or had control over the dog and area. These cases are fact-specific.
