Dog bites, breed lists and homeowners liability
Liability coverage usually pays when your dog bites someone, unless the insurer excluded the dog. How breed lists, bite history and state law work.
A standard homeowners policy covers a dog bite. The liability section pays the injured person's medical bills and other damages if you are legally responsible, and it pays a lawyer to defend you, up to the limit on your declarations page. The trouble is not the standard form but the fine print attached to it: insurers can decline a breed, exclude a dog after a bite, or cap dog claims at a low sublimit, and any of those changes quietly removes the protection you assumed you had.
The wording discussed here comes from the ISO homeowners form HO 00 03 05 11. Your insurer's own form and any endorsements attached to it control, so read the endorsement list on your declarations page before you rely on any of this.
How the policy responds to a bite
Two parts of Section II apply when your dog hurts someone. personal liability (Coverage E) pays damages you owe because of bodily injury or property damage caused by an occurrence, and it provides a defense even if the suit is groundless. medical payments to others (Coverage F) pays necessary medical expenses regardless of fault. Under the ISO form, Coverage F extends to a person on your property with permission and to an injury off your property that is caused by an animal owned by or in the care of an insured. A jogger bitten on the sidewalk is therefore within Coverage F's reach. The form's limit is per person, and many policies start at $1,000, so it covers the urgent-care visit, not the surgery.
| Situation | Usual result under the ISO form |
|---|---|
| Your dog bites a delivery driver at your door | Coverage F pays medical bills; Coverage E responds to a claim for more |
| Your dog bites a passerby on a walk | Same; the form reaches animals owned by an insured off the premises |
| Your dog injures a neighbor's dog | Property damage claim under Coverage E; the law generally treats pets as property |
| Your dog knocks down a guest, who fractures a hip | A bodily injury claim; the bite is not required |
| Your dog bites you or a resident family member | Not covered; injury to an insured is excluded, and Coverage F excludes regular residents |
| You train or board other people's dogs for pay | Business exclusions can apply (Liability exclusions: what Coverage E won't pay) |
| An endorsement excludes your dog | No coverage, and no defense, for claims arising from that dog |
Injuries from dogs are not limited to bites. Triple-I and State Farm estimated that dog-related injury claims cost homeowners insurers $1.86 billion in 2025, across 28,450 claims averaging $65,450, and the count includes fractures and other blunt trauma. Claim counts rose about 25.6% from 2024, while the average claim fell about 5.5% (Triple-I, accessed October 2026). California, Florida, Michigan and Ohio had the most claims, and New York had the highest average cost, at $92,154. Those numbers explain why underwriters ask about dogs. They are not a reason to assume your own claim would be small: an average sits well below what a deep facial wound or a child's reconstructive surgery can cost.
Whether you are liable depends on your state
Coverage E pays only if you are legally liable, and the law that decides that varies. Triple-I describes three frameworks: a dog-bite statute that makes the owner liable without proof of prior aggression, the "one-bite" rule that requires the owner to have known the dog was likely to cause that kind of harm, and ordinary negligence. As of March 2021 it counted 29 states with owner-liability laws that carry exceptions such as provocation, and 17 states plus D.C. without automatic liability, along with a few with no dog bite statute at all.
| Framework | What the injured person must show | What a defense looks like |
|---|---|---|
| Dog-bite statute | The dog bit them while they were in a public place or lawfully on private property | Provocation, trespass, the person's own carelessness |
| One-bite rule | The owner knew or should have known of a dangerous tendency | No warning signs, no history |
| Negligence | The owner failed to use reasonable care (a gate left open, a leash not used) | The owner acted reasonably |
Florida shows how a statute works. Under Fla. Stat. 767.04, the owner of a dog that bites a person in a public place, or lawfully on private property, is liable for damages "regardless of the former viciousness of the dog or the owners' knowledge of such viciousness." The bitten person's own negligence reduces the award by their share of fault. A prominently posted "Bad Dog" sign defeats liability to people age 6 or older unless the owner's negligence caused the injury, and it never helps against a child under 6. See Florida for the broader market and rules there.
Two points follow. A sign, a fence or a "friendly dog" is not a defense in a strict-liability state, and a clean record is not a defense in a negligence state if the gate was open. And because local leash and dangerous-dog ordinances can create liability by themselves, a violation such as an unleashed dog can matter even when state law is generous to owners. Ask an attorney about your state's rules if a claim arises.
Breed lists and what insurers actually do
There is no industry-wide list. According to Triple-I, some insurers will not write owners of dogs they categorize as dangerous, with pit bulls the usual example. Others decide case by case on whether the individual dog has been deemed vicious, and some do not ask about breed at all. Insurers that do write these dogs may charge more, require a signed liability waiver, or cover the dog only if the owner takes the dog to behavior classes or restrains it with a muzzle, chain or cage. After a bite, the insurer may raise the premium, nonrenew the policy or exclude the dog.
Look for these three outcomes in your own paperwork:
- Underwriting refusal. The insurer declines to quote or renew because of the breed or a bite history. The policy itself never mentions the dog.
- A breed exclusion in the policy. AAA - Automobile Club of Southern California, for example, says on its own pages that liability coverage excludes certain breeds, purebred or hybrid. Other insurers do something similar by endorsement.
- A specific-dog exclusion or sublimit. After a bite, an animal liability exclusion endorsement can remove coverage for claims arising from that dog or from any dog. Some Florida carriers sell animal liability as an optional coverage with its own cap: Southern Oak Insurance lists a $25,000 liability sublimit with $2,000 of medical payments, and Kingstone Insurance sells canine legal liability for dog owners. Treat any such cap as the real dog limit, not the $300,000 on the declarations page.
Regulators do police these decisions. In October 2025, Maine's Bureau of Insurance barred a nonrenewal by Homesite Insurance Company of the Midwest, after a hearing, because the company cited a dog with a bite history but could not show the bite occurred on the insured property, which Maine's cancellation law requires (see the Homesite Insurance profile and the Bureau's decision). If you receive a nonrenewal notice, your home insurance was nonrenewed: what to do now covers your options.
State laws against breed discrimination
A growing number of states restrict breed-based underwriting, usually while preserving the insurer's right to act on a dog's actual behavior.
- Nevada. SB 103, effective January 1, 2022, bars homeowner's, renter's, mobile home and vehicle umbrella insurers from refusing or canceling coverage, or raising premiums, based solely on breed. Insurers may not ask the breed but may ask whether a dog has been declared dangerous or vicious (AKC summary). See Nevada.
- New York and Colorado. The ASPCA counts both, along with Nevada, among states that bar insurers from denying coverage on the basis of breed and require them to assess each dog individually (ASPCA). New York's law, signed in 2021, leaves insurers free to act when a resident dog of any breed has a history of aggression (ASPCA). Colorado's breed provision was expanded in 2025 by HB 25-1207, and insurers may still act on a dog known or declared to be dangerous (AAIS). See New York and Colorado.
- Michigan and Pennsylvania. Triple-I notes that laws in Michigan and Pennsylvania bar insurers, in some circumstances, from canceling or denying coverage over breed. The protection is narrower than a flat ban, and bills to broaden it have been introduced, so confirm the current rule with the state insurance department. See Michigan and Pennsylvania.
Where such a law applies, it limits breed as the sole reason. It does not prevent an insurer from acting on a bite.
If your dog is excluded or your insurer will not cover it
- Read the exclusion. Find the wording in the endorsement list. An exclusion for one named dog is narrower than one for all dogs or all animals.
- Ask whether the cap is a sublimit. A $25,000 or $50,000 animal limit can disappear quickly in a surgery case.
- Price a standalone canine liability policy. Several specialty insurers sell dog-owner liability apart from the homeowners policy, and some Florida homeowners insurers sell their own version as an endorsement.
- Shop other insurers. Policies and appetite differ widely, and a dog that one underwriter excludes may be acceptable to another. captive agents, independent agents and direct insurers explains why an independent agent can see more options.
- Ask whether your umbrella follows the dog rules. Many umbrella carriers apply their own animal exclusions, so check the umbrella separately (umbrella insurance for homeowners: what it adds and where it stops).
- Know your state's dangerous-dog insurance rule. Triple-I reports that Ohio requires owners of dogs classified as vicious to carry at least $100,000 in liability coverage.
A worked example (hypothetical)
Say your Coverage E limit is $300,000 and your Coverage F limit is $5,000. Your dog bites a delivery driver on your porch. The driver's medical bills reach $38,000, lost wages $12,000, and the lawyer demands $180,000.
- Coverage F can pay up to $5,000 of the medical bills with no finding of fault.
- Coverage E responds to the demand. If liability is clear in your state, the insurer settles within the $300,000 limit, and defense costs are paid on top of that limit under the form's Additional Coverages for claim expenses.
- If the settlement or verdict reached $450,000, you would owe the $150,000 above the limit unless an umbrella applied.
Now change one fact: a bite last year led your insurer to attach a dog exclusion at renewal. The same claim receives no coverage and no defense, and you pay both the damages and your own attorney. The renewal notice that added the endorsement is the document that decides the case, which is why it is worth reading.
After a bite: what to do
- Get the person medical care. The policy pays for first aid you provide.
- Hold the dog securely and follow local animal control rules, including quarantine or rabies records.
- Exchange contact details and photograph the scene, the gate and the injury, without discussing fault.
- Do not promise to pay. The form provides that an insured who voluntarily pays or assumes an obligation does so at his or her own cost, apart from first aid.
- Notify your insurer in writing right away, and forward every demand letter and summons. See what happens when someone sues you after an injury at your home for what happens in a suit.
- Ask the agent about renewal before the next billing cycle, so a surprise exclusion does not arrive unnoticed.
Key takeaways
- The ISO homeowners form covers dog bite liability on and off your property, but endorsements, sublimits and underwriting decisions can remove it.
- Whether you owe damages turns on state law: dog-bite statutes, the one-bite rule or negligence. Signs and fences do not reliably protect you.
- Breed rules vary by insurer. Nevada, New York and Colorado restrict breed-based underwriting, and Michigan and Pennsylvania have narrower protections.
- An exclusion or low animal sublimit means neither coverage nor a defense, so read your endorsement list and ask before you adopt.
- Triple-I reported a $65,450 average dog-related injury claim in 2025. Check your liability limit with the homeowners coverage gap checker and consider an umbrella.
