A dog bite happens in a matter of seconds, but the legal and financial consequences that follow can stretch on for months or even years. If your dog has just bitten someone in South Dakota, the first thing you need to understand is that the state’s approach to dog bite liability is significantly different from most of the country — and knowing exactly where you stand matters immediately.
South Dakota operates under what is known as the “one-bite rule,” a legal standard that places the burden of proof on the victim rather than automatically holding you responsible. That distinction shapes everything from whether you face a civil lawsuit to what happens to your dog and your insurance policy.
This guide walks you through each stage of what happens if your dog bites someone in South Dakota — from the law itself to your immediate obligations, your dog’s fate, dangerous dog designations, insurance exposure, and potential criminal liability.
South Dakota’s Liability Standard: Strict Liability vs. the One-Bite Rule
Most people assume that if their dog bites someone, they are automatically on the hook. In many states, that is exactly how it works. South Dakota, however, takes a different path.
There is no South Dakota dog bite statute. The South Dakota Supreme Court has ruled that a dog owner is liable for harm done by the dog if they know or have reason to know that the dog is abnormally dangerous, or if they are negligent in failing to prevent the harm. This means liability is not automatic — it hinges on what you knew, or should have known, about your dog’s behavior.
While South Dakota has no official dog bite law, there is a one-bite rule that holds owners liable if they knew or should have known their dog would be dangerous. The one-bite rule ultimately gives dog owners the benefit of the doubt in bite cases by assuming their dog may not have given them any reason to believe it would injure someone in the past, so they are not responsible for the first bite.
Key Insight: The “one-bite rule” doesn’t literally mean your dog gets one free bite. It means the victim must prove you had prior knowledge — or should have had prior knowledge — that your dog was dangerous.
Under South Dakota law, a victim can pursue you through two main legal theories. Under South Dakota law, a cause of action by someone injured by a domestic animal can arise under a theory of scienter (common law strict liability) or negligence, and a negligence case does not require proof that the dog was vicious.
Under South Dakota law, owners of domestic animals may be held liable under a theory of scienter (intentionally letting the dog bite) or in a case of negligence (not taking appropriate action to protect the victim). Under a theory of scienter, the victim (plaintiff) must prove to the court that the dog owner had knowledge of their dog’s aggression and permitted it to attack them.
What counts as prior knowledge? The injured person must prove the owner knew about the dog’s dangerous tendencies. This proof can come from past complaints about aggressive behavior, the dog’s training history, or even common beliefs about specific breeds. Courts today also consider growling, lunging, and general temperament — not just a documented prior bite.
If a dog bites someone for the first time, the owner is now on notice that their dog may be potentially dangerous. From that point forward, the owner has a responsibility to take reasonable precautions to prevent future attacks. If the owner fails to do so and the dog attacks someone again, they may be considered negligent and liable for any resulting damages.
South Dakota also prohibits breed-specific legislation at the local level. Under South Dakota Codified Law 40-34-16, local governments are not allowed to ban any dog breeds, but they are allowed to pass regulations relating to all dogs. Furthermore, Senate Bill 75, passed on July 1, 2014, prohibits dog breed discrimination in court. This means your dog’s breed alone cannot be used against you in a South Dakota courtroom.

For comparison, states like Connecticut and Florida use strict liability statutes, meaning owners there are automatically responsible regardless of prior knowledge.

Your Immediate Legal Obligations After Your Dog Bites Someone in South Dakota
Once a bite occurs, the clock starts immediately. The steps you take — or fail to take — in the hours and days following the incident can directly affect your legal exposure and your dog’s outcome.
Your first priority is to ensure the victim receives medical attention. If the victim has not already received medical treatment, it is crucial that they do so as soon as possible. While it is important for their health, receiving a medical exam after a dog bite can also protect legal interests. Without medical documentation, an injury claim against the liable party may lose credence.
Next, you are expected to report the bite. An animal owner or caregiver that is responsible for the pet at the time of the bite is responsible to report the bite immediately. You should report the attack to your local South Dakota animal control office. Importantly, reporting that your pet has bitten someone does not mean it will be euthanized. Animal Control wants you to report the bite so they can verify its rabies vaccinations and arrange a 10-day quarantine.
Pro Tip: Contact your homeowner’s or renter’s insurance provider promptly after the bite. Delayed reporting can complicate or jeopardize your coverage.
Vaccination status matters enormously here. If an unvaccinated dog bites someone in South Dakota, the state will consider them a potential rabies carrier. The dog may go into quarantine and/or face euthanasia. If they are not showing symptoms of rabies, they will go through a ten-day quarantine to check for developing symptoms.
All dogs residing in South Dakota must receive a rabies vaccination by three months of age. After their first vaccination, owners must vaccinate their dogs either annually or triannually depending on the vaccination they receive. Keeping your dog current on vaccinations is not just good pet ownership — it is a legal safeguard that can prevent your dog from facing a much harsher outcome after a bite.
You should also gather documentation. If you contacted the police after the incident, you should seek a copy of the police report. If you have not yet notified the police, you may still do so after the accident occurred. The police report may also include contact information from witnesses of the dog bite, which can potentially support any claim.
Keep in mind that because South Dakota has no dog bite statute, victims must take legal action according to the state’s personal injury law (S.D. Codified Law 15-2-14.3). This sets a three-year statute of limitations on the time a victim has to file a claim against the dog owner for the injury. That three-year window means the threat of a lawsuit doesn’t disappear quickly.
South Dakota does not permit animals to free roam. Some cities in South Dakota set additional leash laws to protect animals and citizens, and it is important to take local rules into account. The only time dogs are allowed off-leash in public is when they are in a designated off-leash area, such as a dog park. A bite that occurs while your dog is off-leash in a non-designated area can significantly strengthen a negligence claim against you.
What Happens to Your Dog After a Bite in South Dakota
One of the most immediate concerns for any dog owner after a bite incident is what will happen to the dog itself. South Dakota law does address this — and the outcome depends heavily on the severity of the bite and whether your dog has any prior history.
The mandatory first step is quarantine. Animal Control will verify your dog’s rabies vaccination status and place the dog under a 10-day observation period. If the dog is currently vaccinated, this quarantine can often be completed at home under specific conditions set by animal control. An unvaccinated dog, however, faces a mandatory facility quarantine and potential euthanasia.
After one documented bite, the state of South Dakota considers a dog vicious. This means that subsequent bites may lead to euthanasia. Additionally, a severe enough attack could lead the court to determine euthanasia is the best course of action even for a first offender.
Important Note: A single severe mauling can result in euthanasia even if it is your dog’s first recorded incident. Severity of injury, not just bite history, factors into the outcome.
A dangerous dog, particularly a repeat offender, may be euthanized if this is determined to be in the best interest of the safety of the community. After one documented bite, the state of South Dakota considers a dog vicious. Subsequent bites may lead to euthanasia.
There are, however, circumstances under which your dog will not be considered the aggressor. There are cases where dogs will not be considered aggressors in attacks, even if previously proven to be dangerous. Dog owners are not responsible for attacks in which the dog was provoked or protecting the owner. This could include yelling at, hitting, or throwing objects at the dog.
No dog may be declared vicious if an injury or damage is sustained to any person who was committing a willful trespass or other tort upon premises occupied by the owner or keeper of the dog, or who was teasing, tormenting, abusing or assaulting the dog, or was committing or attempting to commit a crime.
South Dakota is home to a wide variety of wildlife and biting insects that residents deal with regularly, from stinging insects to biting flies — but a domestic dog bite carries a distinct legal weight that wild animal encounters do not. The law focuses specifically on owner responsibility and the dog’s documented history.
Dangerous Dog Designation and What It Means for You in South Dakota
If your dog is labeled dangerous or vicious under South Dakota law, a new set of obligations immediately applies to you as the owner — and the consequences of non-compliance can be serious.
South Dakota’s vicious dog provisions are codified in Chapter 40-34. This South Dakota statute provides that a vicious dog is defined as any dog which, when unprovoked, in a vicious manner approaches in apparent attitude of attack, or bites, or otherwise attacks a human being, including a mailman, meter reader, serviceman, etc., who is on private property by reason of permission of the owner.
Any person owning or keeping a vicious dog as defined in §§ 40-34-13 to 40-34-15, inclusive, has committed a public nuisance and is subject to the provisions of §§ 21-10-5 and 21-10-9. Being designated a public nuisance carries legal consequences that can include court-ordered action against both you and the dog.
Common Mistake: Many owners assume a dangerous dog designation only affects their dog’s future. In reality, it also immediately changes your legal obligations, insurance requirements, and potential criminal exposure.
At the local level, dangerous dog designations typically come with requirements such as secure containment, prominent warning signage on your property, mandatory muzzling in public, and microchipping. Dangerous dog designation can require special registration, expensive liability insurance, and secure containment measures.
Local ordinances in cities like Sioux Falls and Rapid City may impose additional registration requirements and fees on top of state law. Individuals who own or possess a dog in South Dakota are required to obtain a pet license. The license validity period and requirement deadline depend on the ordinance in one’s city or town. For instance, Sioux Falls requires all dogs and cats to have a license that can be valid for either a year or three years.
South Dakota requires that owners keep their dog under “reasonable control” as part of their standard. Failing to maintain reasonable control after a dangerous dog designation dramatically increases your civil and criminal liability if another bite occurs.

Insurance Coverage and Financial Liability in South Dakota
Even if you are not found criminally liable for your dog’s bite, the financial consequences of a civil claim can be substantial. Understanding your insurance situation before — and immediately after — a bite is critical.
For dog owners, homeowners or renters insurance typically provides the first line of financial defense, with coverage limits usually between $100,000 and $300,000. However, some policies exclude certain breeds or dogs with previous incidents, so it’s worth checking your coverage before an incident occurs.
Liability claims related to dog bites and other dog-related injuries cost homeowners insurers $1,570 million in 2024, according to the Insurance Information Institute and State Farm. The number of dog bite claims nationwide increased in 2024 to 22,658 from 19,062 in 2023 — an 18.9 percent increase. The average cost per claim increased 18.3 percent in 2024 to $69,272 from $58,545 in 2023.
Those national figures illustrate why insurers are paying close attention to dog bite claims. After a bite incident, your insurer’s response may vary significantly.
| Insurance Scenario | Likely Outcome |
|---|---|
| First bite, no prior complaints, vaccinated dog | Claim likely covered; possible premium increase |
| First bite, dog with documented aggression history | Coverage may be disputed; policy review likely |
| Repeat bite or dangerous dog designation | Policy non-renewal or breed/dog exclusion likely |
| Dog not listed on policy or excluded breed | Claim likely denied; out-of-pocket liability |
Once a dog has bitten someone, it poses an increased risk. The insurance company may charge a higher premium, nonrenew the homeowner’s insurance policy, or exclude the dog from coverage. Some insurance companies will not insure homeowners who own certain breeds of dogs categorized as dangerous. Others decide on a case-by-case basis, depending on whether an individual dog, regardless of its breed, has been deemed vicious.
If a lawsuit moves forward against you, the financial stakes are significant. In South Dakota, owners of vicious or dangerous dogs are liable for any injuries or damage a bite victim may sustain. They may be ordered to provide compensatory damages, ranging from present and future medical bills to physical therapy costs and rehabilitation expenses. They may also be liable for the victim’s lost wages, pain and suffering, and the victim’s family’s loss of consortium.
In extreme cases, punitive damages are also on the table. Punitive damages may be available if the dog owner knew that their dog was vicious and had a history of attacking people, yet failed to take adequate precautions to prevent future attacks. This is precisely why acting responsibly after a first bite — and securing proper insurance coverage — is so important.

Criminal Charges for Dog Bites in South Dakota
Most dog bite cases in South Dakota are resolved through civil law — meaning the victim sues for monetary damages. However, in certain circumstances, you could also face criminal charges as a dog owner, and this is a dimension of the law that many people overlook entirely.
Dog owners could be charged with serious crimes if their dogs attack and severely injure people. In 17 states and the District of Columbia, liability is not automatically granted but attacks are classified as misdemeanors or, in extreme cases, as felonies, with fines. South Dakota falls within this broader framework where criminal exposure is possible depending on the severity of the incident and the owner’s conduct.
The key factors that elevate a dog bite from a civil matter to a potential criminal one include:
- You knew your dog had a dangerous history and failed to take reasonable precautions
- Your dog was off-leash or unrestrained in violation of local ordinances at the time of the bite
- The attack resulted in serious bodily injury or death
- You were found to have intentionally used your dog as a weapon or to intimidate
- The bite involved a repeat offender dog that you had been previously warned about
Pro Tip: If the bite is severe or involves a known dangerous dog, consult a criminal defense attorney immediately — not just a civil personal injury attorney. The two areas of law can interact in complex ways.
The dog owner must be concerned with the local county and municipal codes as well as state law. Furthermore, violation of a county or municipal code section might lead to more serious charges under state law, such as where the dog owner violates a municipal code provision and the victim dies — possibly resulting in a felony prosecution for manslaughter.
South Dakota’s animal cruelty statutes also intersect with dog bite law. As in the other 49 states, dogfighting is a felony in South Dakota. Charges can also occur for those betting on or attending dogfights in South Dakota. It’s also illegal to train dogs for the intent of fighting, even if you aren’t directly participating in dogfights. If evidence emerges that a biting dog was trained aggressively or kept for fighting, criminal exposure escalates dramatically.
It’s also worth noting that a criminal conviction can complicate civil recovery for the victim. This is another reason why the interaction between criminal and civil proceedings in dog bite cases requires careful legal navigation — both for the dog owner and the injured party.
If you are a dog owner in South Dakota, understanding the full legal landscape is your best form of protection. Keeping your dog vaccinated, properly licensed, leashed in public, and well-socialized dramatically reduces your legal risk.

Final Thoughts
A dog bite in South Dakota puts you at the intersection of civil liability, animal control law, insurance policy, and potentially criminal statute — all at once. The state’s one-bite rule means your liability is not automatic, but it is far from zero, and the consequences can be significant if your dog has any history of aggression or if the bite causes serious injury.
Your most important steps are to report the bite immediately, ensure your dog’s vaccinations are current, cooperate with animal control, and contact both your insurance provider and a qualified South Dakota personal injury attorney as soon as possible. Acting quickly and responsibly not only protects the victim — it also gives you the strongest possible legal footing going forward.
