Delaware Dog Bite Law decides who pays when a dog injures someone — and the answer changes a great deal from one state to the next. This guide explains whether Delaware uses strict liability or the one-bite rule, how long you have to file, how leash and dangerous dog rules work, and exactly how a homeowners policy responds. Whether you own a dog in Delaware or you were bitten by one, Delaware Dog Bite Law is what determines the outcome.
Delaware Dog Bite Law is summarized here in plain English. Everything in this guide was verified against Delaware statutes, the state courts, and Insurance Information Institute claim data as of August 2026.
In This Delaware Dog Bite Law Guide:
Delaware Dog Bite Law: Strict Liability or One-Bite Rule?
Delaware is a strict liability state for dog bites. That means a dog owner is responsible for the injury even if the dog had never bitten anyone before and even if the owner did everything right. The victim does not have to prove the owner was careless.
The governing statute is 16 Del. C. § 3053F. Statutes are amended, so confirm the current text before relying on it in a claim.
A dog owner in Delaware is liable in damages for any injury, death, or loss to a person or property caused by the dog, with no need to show the owner knew the dog was dangerous — there is no “free first bite.” A victim only has to prove the dog caused the harm and the amount of damages. The owner escapes liability only if the injured person was trespassing or committing a criminal offense on the owner’s property, was committing a criminal offense against any person, or was teasing, tormenting, or abusing the dog.
The Delaware rule is broad — it covers not just bites but other injuries a dog causes, such as knocking a person down.
Filing Deadline Under Delaware Dog Bite Law
A dog bite lawsuit in Delaware must be filed within 2 years of the date of the injury (10 Del. C. § 8119). Miss that deadline and the claim is normally barred no matter how strong it is.
The deadline for notifying an insurance company is much shorter than the deadline for filing suit. Most homeowners policies require prompt notice, so report the incident to the insurer right away even if you have not decided whether to sue.
How Delaware Dog Bite Law Treats Leash Laws and Dangerous Dogs
16 Del. C. § 3048F makes it a statewide violation to let a dog run at large; when off the owner’s property a dog must be on a leash capable of physically restraining it, with fines of 25 to 50 dollars for a first offense and 50 to 100 dollars for repeats within 12 months. Exceptions cover working, hunting, herding, law-enforcement, search-and-rescue and service dogs actively performing, dogs on the owner’s own property or on private property with permission, dogs inside vehicles, and attended dogs in designated off-leash areas.
Under 16 Del. C. ch. 30F, subch. V, an animal welfare officer may seize a dog and petition the Justice of the Peace Court, which can declare a dog “potentially dangerous” or “dangerous” based on proven conduct (attacks or injuries to people or domestic animals) rather than breed. A declared dog must be confined in a proper enclosure, muzzled and leashed on a 6-foot lead under an adult’s control when off the premises, registered, and may not be sold or given away; a dangerous-dog finding can result in court-ordered euthanasia.
Liability insurance requirement: YES — $100,000 liability insurance covering damage or injury caused by the dog (16 Del. C. ch. 30F, subch. V). This is a legal obligation once a dog is formally declared dangerous, and a standard homeowners policy may not satisfy it.
Leash rules matter far beyond the ticket. In a strict liability state, breaking a leash ordinance is powerful evidence of negligence, and it can defeat an owner’s defense outright.
Delaware Dog Bite Law and Homeowners Insurance
Dog bites are normally paid under the personal liability section of a standard homeowners policy — Coverage E — not under the part that repairs your house. Renters policies carry the same liability coverage.
Two other pieces of the policy come into play. Medical payments coverage (Coverage F) pays a modest amount of the injured person’s medical bills with no finding of fault, which often settles a minor bite quietly. And an umbrella policy sits above your liability limit — the single most useful thing a dog owner in Delaware can buy.
Coverage is not automatic. Most policies exclude injuries to people who live in your household, deliberate acts, and business-related animals. Some exclude a dog with a prior bite on record. Read the exclusions before you need them, not after.

Unique to Delaware: Delaware became the 19th state to bar breed-specific legislation (HB 13, signed June 2, 2017) — no dog may be declared dangerous or potentially dangerous based on breed, and no county or municipality may regulate dogs by breed. Delaware also pairs an unusually broad strict-liability statute (all injuries and property damage, not just bites) with a statewide leash law and a mandatory 100000 liability insurance requirement for court-declared dangerous dogs. Dangerous-dog determinations are made by the Justice of the Peace Court, not an administrative panel.
Dog Bite Claim Costs in Delaware
Delaware Dog Bite Law decides who is liable. The claim figures below show what that liability actually costs when it lands.
State-level claim counts for Delaware were not available from the Insurance Information Institute at the time of writing. Nationally, dog bite and dog-related injury claims are among the costliest homeowners liability claims, and the average payout has risen every year for over a decade.
| Typical liability limit | $300,000 |
Delaware Dog Bite Law, Breed Restrictions and Insurance Exclusions
Delaware law bars cities and counties from banning specific breeds, so a local pit bull ordinance is not enforceable against you here.
Insurers in Delaware are generally free to refuse or surcharge coverage based on breed. This is a real risk — a policy can be non-renewed after an insurer learns which dog lives at the address.
Breeds most often excluded or surcharged by insurers:
- pit bull
- rottweiler
- doberman pinscher
- german shepherd
- chow chow
- akita
- presa canario
- wolf hybrid
Landlord and Property Owner Liability
The strict-liability statute reaches the dog’s “owner,” which includes anyone who keeps, harbors, or has custody of the dog, so a landlord who merely rents to a dog owner is generally not strictly liable. A Delaware landlord can still face ordinary negligence liability where it knew of a tenant’s dangerous dog on the premises and failed to take reasonable steps to protect others (see Pettinaro Enterprises v. Kling, Del. Super. 2011).
Under Delaware Dog Bite Law the tenant who owns the dog is the first target of a claim, but a landlord with knowledge of a dangerous animal can be pulled in alongside them.
If you rent out property in Delaware, this is worth taking seriously — see our guide to liability coverage and what happens when someone is hurt on your property.
Defenses Available Under Delaware Dog Bite Law
Defenses recognized in Delaware:
- Trespassing
- Criminal offense by the injured person
- Provocation (teasing
- Tormenting
- Or abusing the dog)
- Comparative fault (Delaware modified comparative negligence
- 10 Del. C. § 8132)
These defenses rarely erase a claim by themselves. They more often reduce what an owner pays, which under comparative fault rules can still be a substantial difference.
How to Lower Your Liability Risk
Delaware Dog Bite Law sets the standard you will be judged against. These are the steps that reduce both the chance of a bite and the size of the bill if one happens:
- Raise your liability limit. Going from $100,000 to $300,000 usually costs very little per year.
- Add an umbrella policy. $1 million of extra liability typically runs $150-$300 a year.
- Tell your insurer about the dog. A non-disclosed dog is a reason to deny the claim later.
- Check your local leash ordinance. A violation is evidence against you in a civil case.
- Secure the yard and post a sign. Fencing and gate latches prevent the bite in the first place.
- Document training and vet visits. A record of responsible ownership supports the defense that you had no notice the dog was dangerous.
