Dog Bite Statute of Limitations in Delaware: How Long You Really Have to File

If a dog bit you in Delaware, the clock on your legal claim started running the moment it happened, even if you were too busy dealing with stitches, X-rays, or a frightened child to think about lawsuits. The Delaware dog bite statute of limitations gives most victims a firm two-year window, and missing it can end your case before it starts. Here is exactly how long you have, when the countdown begins, and which situations can change your deadline entirely.

How Long Do You Have to File a Dog Bite Lawsuit in Delaware

Under 10 Del. C. § 8119, the statute of limitations for personal injury claims in Delaware is 2 years from the date the injury occurred, and this deadline applies to all dog bite claims. That two-year window covers medical expenses, lost wages, pain and suffering, and any other damages tied to the attack. Individuals injured in a dog bite or personal injury incident have two years from the incident date to file a lawsuit, and this deadline also applies to cases involving wrongful death or property damage resulting from the incident.

Delaware backs this deadline with one of the strongest dog owner liability laws in the country. Delaware is a strict liability state for dog bite injuries, and under 16 Del. C. § 3053F, the owner of a dog is liable in damages for any injury, death, or loss to person or property caused by that dog, with no requirement that the owner knew the dog was dangerous or that the victim prove negligence. That is very different from states following the older common-law approach, where an owner only faces liability after a dog has already shown aggressive tendencies. If you want to see how that alternative system works, this breakdown of the one-bite rule in Pennsylvania shows just how much more victim-friendly Delaware’s law is by comparison.

The statute is not limited to bites either. Injuries that occur from other dog behavior such as jumping on and knocking a person to the ground are also covered by the Delaware dog bite law. A quick look at the deadlines across claim types shows how consistent Delaware keeps things:

Claim Type	Filing Deadline	Governing Law
Dog bite personal injury	2 years from date of injury	10 Del. C. § 8119
Property damage caused by a dog	2 years from date of loss	10 Del. C. § 8119
Wrongful death from a dog attack	2 years from date of death	10 Del. C. § 3724
Claim against a government entity	2 years, plus 90-day notice	10 Del. C. § 8113

For a deeper look at how liability actually plays out after an attack, see this guide on what happens if a dog bites someone in Delaware. Because the injuries themselves can range from minor punctures to wounds requiring reconstructive surgery, it also helps to understand which breeds and animals generate the most force behind a bite, covered in this rundown of dog breeds with the strongest bite force.

When the Statute of Limitations Clock Starts in Delaware

In most Delaware dog bite cases, the two-year clock starts on the exact date of the attack, not the date you finished treatment or the date you decided to pursue a claim. This matters because victims often delay contacting an attorney while they focus on recovery, unaware that the deadline is already running in the background. Due to this strict timeline, it is important that dog bite victims contact an experienced dog bite lawyer as soon as possible, since your attorney can help you understand your rights and ensure that all deadlines are met.

Delaware courts do recognize a discovery rule in limited circumstances, but do not count on it for a typical dog bite case. Delaware courts have recognized limited discovery rule exceptions in certain case types, though Delaware courts apply the discovery rule cautiously and require clear evidence that the injury could not have been discovered through reasonable diligence. Since a dog bite is an obvious, immediate injury, the discovery rule almost never extends the deadline the way it might in a case involving a delayed medical diagnosis.

The starting point can also shift if the dog was unleashed or running loose when the attack happened. Delaware law states that no dog is allowed to run at large and must be secured by a leash, with some limited exceptions, and if a dog owner violates this law, they will be deemed negligent. That negligence per se angle can strengthen a claim even when strict liability defenses come into play. For the specifics on when and where dogs must be restrained statewide, review these dog leash laws in Delaware.

Pro Tip: Write down the exact date, time, and location of the attack as soon as possible. Delaware’s two-year deadline runs from that specific date, and a vague memory months later can create unnecessary disputes with an insurance adjuster.

Exceptions That Can Pause or Extend the Deadline in Delaware

A handful of legal doctrines can pause, or “toll,” the statute of limitations in specific situations. Tolling is available for plaintiffs under legal disability, such as minors or incompetent persons, under 10 Del. C. § 8116, which suspends the period until the disability is removed, and fraudulent concealment by a defendant can also toll the period under Delaware common law. If a dog owner actively hid information relevant to your claim, that concealment could extend your filing window.

Delaware law also protects victims when a defendant cannot be located within the state. Under the savings provision for infants or persons under disability, if at the time a cause of action accrues the responsible person is out of the state, the action may be commenced within the time limited after that person comes into the state in a manner allowing reasonable diligence to serve process. This provision matters if a dog owner moves out of Delaware shortly after an attack and cannot be served with a lawsuit right away.

Outside of these narrow tolling doctrines, Delaware’s strict liability framework still leaves room for a handful of defenses that affect the underlying claim rather than the deadline itself. The exception to strict liability is strictly limited to three scenarios: the victim was trespassing or committing a crime on the owner’s property, the victim was committing a crime against any person, or the victim was abusing, tormenting, or teasing the animal, and for the second exception the victim does not have to be on the owner’s property.

Common Mistake: Assuming that a delayed diagnosis, like nerve damage that worsens over time, automatically extends your deadline. Delaware courts require strong proof before applying the discovery rule to an obvious injury like a dog bite, so do not rely on it as a backup plan.

Special Rules for Minors in Delaware

Children make up a disproportionate share of dog bite victims, and Delaware law accounts for that with special tolling rules. Under 10 Del. C. § 8116, the statute of limitations is tolled, or paused, until the minor reaches age 18, at which point the applicable statute of limitations begins to run. The American Veterinary Medical Association journal published a ten-year study of dog bites that found nearly half the victims of fatal attacks were children, which makes this protection especially relevant for families dealing with a serious attack.

Important Note: Sources differ slightly on exactly how much time a minor gets after turning 18. One legal source states that a minor who suffers a personal injury probably has three years from their 18th birthday to file a lawsuit under Del. Code tit. 10, § 8116, while other guidance describes the standard two-year window simply beginning at age 18 rather than being extended to three years. Because this distinction can determine whether a claim is still valid, confirm the exact deadline with a Delaware attorney before assuming either timeline applies to your child’s case.

Regardless of which interpretation controls, waiting until a minor’s tolling period is close to expiring is risky. Evidence fades, witnesses move away, and animal control records can be purged after a few years. If your child was bitten by a dog with a documented history of aggression, it also helps to understand how bite force and breed factor into liability discussions, covered in this overview of animals with the strongest bite force.

Filing Against a Government-Owned or Stray Dog in Delaware

Claims involving a government-owned dog, a police K-9, or an animal under a municipal shelter’s control follow a different procedural path than a typical neighbor-versus-neighbor dog bite case. Suing government entities in Delaware requires navigating the Delaware Tort Claims Act, found at 10 Del. C. § 4001 et seq., which waives sovereign immunity in certain circumstances but imposes strict procedural requirements. Missing a procedural step here can bar your claim even if you technically file within the standard two-year window.

The most important extra step is early notice. Before filing a lawsuit against the State of Delaware, you must provide written notice to the Delaware Attorney General within 90 days of the incident under 10 Del. C. § 8113. That 90-day window runs alongside, not instead of, the two-year statute of limitations, so both deadlines need attention. Notice requirements and damages caps apply, and as of the codified statute, the cap on damages against the State is $300,000 per occurrence.

Stray or unowned dogs raise a different problem: strict liability under Delaware’s dog bite statute depends on identifying an owner, keeper, or harborer. Delaware courts have shown they will not let organizations dodge that responsibility easily. In one case, a plaintiff bitten by a dog at a facility operated by an animal welfare organization invoked Delaware’s dog bite statute, and the Delaware Supreme Court found that the statute unambiguously imposes strict liability on any person who owns, keeps, harbors, or is the custodian of a dog, without any exception for animal welfare organizations. If a truly stray dog with no identifiable owner caused your injury, your claim may instead need to route through animal control or municipal negligence theories. For context on how Delaware handles other unowned or wild animals on public land, see these roadkill laws in Delaware and this guide on whether it is legal to own a raccoon in Delaware, both of which touch on how the state assigns responsibility for animals without a clear private owner.

What Happens If You Miss the Deadline in Delaware

Missing the statute of limitations in a Delaware dog bite case is close to a guaranteed loss, regardless of how strong your evidence might otherwise be. The court will almost certainly dismiss the lawsuit on a motion by the defendant, regardless of the strength of the underlying claim. If a lawsuit is filed after this timeframe, the defendant may have the right to request its dismissal due to the statute of limitations.

Once a case is dismissed on timeliness grounds, there is generally no second chance. If you fail to file your dog bite claim within this timeframe, you will lose your legal right to recovery and may not be able to pursue compensation for your injuries. Insurance companies also know this deadline well, and some will slow-walk settlement negotiations specifically hoping the statute of limitations expires before you file suit. That is one more reason not to treat an informal conversation with an insurance adjuster as a substitute for filing a formal claim.

What to Do Before the Deadline Approaches in Delaware

Building a strong dog bite claim takes time, and waiting until the deadline is close leaves little room for the investigation a strict liability case still requires. Evidence becomes harder to gather, witnesses forget details, and medical records become less clear over time, so early action protects both your health and your legal position.

1. Get medical attention immediately. Documented treatment ties your injuries directly to the date of the attack, which matters for both the statute of limitations and your damages claim.
2. Identify the dog’s owner or keeper. It must be clearly established that the defendant is the legal owner of the dog that caused the injury, so get names, addresses, and any animal control tags at the scene if it is safe to do so.
3. Report the incident to animal control or local police. An official report creates a timestamped record that supports your version of events years before trial.
4. Photograph injuries, the location, and the dog if possible. Gather evidence such as photos of your injuries, contact information for any witnesses, and details about the dog and its owner.
5. Check for homeowners or renters insurance coverage. Many dog bite settlements are paid through the owner’s homeowners or renters insurance policy rather than out of pocket.
6. Consult a Delaware personal injury attorney well before the two-year mark. Consult with a lawyer who specializes in dog bite cases to discuss your legal options and begin the process of filing a claim.

Severe dog attacks can also raise questions about whether other animals were involved, or whether the injury pattern matches typical bite wounds. If you are documenting wound characteristics for a claim, this comparison of bite force across dog breeds can help explain why some attacks cause deeper tissue damage than others. Acting early, rather than waiting until the two-year deadline is in sight, gives your attorney the runway needed to investigate the owner’s history, negotiate with insurers, and file suit if a fair settlement does not materialize.

Pro Tip: Keep a simple injury journal from day one, noting pain levels, missed work, and follow-up appointments. Delaware juries and insurance adjusters respond to contemporaneous records far more than to recollections written months after the fact.
