If a dog has bitten you in South Dakota, the first legal question you will face is not simply “did it happen?” — it is “did the owner know it could happen?” That distinction defines everything about how your case will be handled in this state.
South Dakota does not have a formal dog bite statute on the books. Instead, the state relies on a combination of common law principles, including the one bite rule and general negligence, to determine whether a dog owner is legally responsible for your injuries. Understanding how that system works is essential before you take any legal action.
Does South Dakota Follow the One Bite Rule?
South Dakota has no dog bite statute but follows the one bite rule in both biting and attack incidents. This is not a minor procedural detail — it shapes the entire burden of proof in a dog bite case and distinguishes South Dakota from the majority of states that impose automatic liability on dog owners.
Through case law, South Dakota’s courts have ruled that the state generally follows the one bite rule, as well as negligence rules to hold dog owners liable. Because there is no statute to point to, the legal standards that apply to your case have been built up through court decisions over many years.
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. That ruling sets the foundation for every dog bite claim brought in the state.
Key Insight: South Dakota is one of a shrinking number of states without a dog bite statute. If you were bitten here, you cannot rely on automatic liability — you must build a case around what the owner knew or should have known.

How the One Bite Rule Works in South Dakota
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. Despite its name, however, the rule is not a simple “free pass” for the first incident.
Courts have not interpreted the common law rule to allow dogs one “free bite.” Instead, the standard requires that an owner should have known that their animal could cause harm before being responsible for the victim’s injuries. A prior bite is simply one way — not the only way — to establish that knowledge.
A dog bite victim in South Dakota can obtain compensation under the doctrines of scienter, negligence, or intentional tort. The state has no dog bite statute and therefore is a “one bite state.” 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.
This means you have more than one legal path available to you. Whether you pursue a scienter claim or a negligence claim will depend on the specific facts of your case, and both approaches are worth understanding before you move forward. You can read more about the full range of consequences in our guide on what happens if a dog bites someone in South Dakota.
What Victims Must Prove Under the One Bite Rule in South Dakota
The path you take — scienter or negligence — determines what you must demonstrate to the court. Both require deliberate, evidence-backed arguments rather than a simple showing that the bite occurred.
Under a theory of scienter, the victim must prove to the court that the dog owner had knowledge of their dog’s aggression and permitted it to attack them. This is the classic one bite rule framework, and it places the heaviest burden on you as the injured party.
In cases of negligence, the plaintiff is not aiming to prove that the dog owner knew their dog was vicious and allowed it to harm them. Instead, they argue that the owner did not take reasonable and appropriate action to warn the plaintiff of the dog bite risk.
Under the negligence route, you must establish three core elements:
- The dog owner owed you a duty of reasonable care
- The owner failed to meet that duty — for example, by not restraining the dog or failing to warn you
- You were directly harmed due to this failure
South Dakota requires that owners kept their dog under “reasonable control” as part of their standard. If the owner let the dog roam unsupervised in a situation where a reasonable person would have foreseen a risk, that failure can support a negligence claim even without a history of prior biting.
Pro Tip: If the dog has never bitten before but the owner failed to leash it in a public area or ignored visible signs of aggression, a negligence claim may be your stronger option. Talk to a personal injury attorney about which theory fits your facts.
What Counts as Prior Knowledge in South Dakota
Prior knowledge is often the deciding factor in a one bite rule case. The good news is that South Dakota courts do not require a previous bite to establish that an owner was aware of their dog’s dangerous nature.
An owner can be held liable for injuries their dog inflicts on another person if the owner knew or should have known that their dog had dangerous propensities. The owner might be deemed to have such knowledge if their dog has previously attacked someone, or if the dog often exhibited signs of aggression — for example, snarling or growling at others.
With the one bite rule, previous aggression can be proven beyond a physical bite. For example, it may be possible to prove that the dog had shown signs of aggression from previous instances of growling or pouncing.
Practical examples of prior knowledge that could support your claim include:
- The dog had bitten or attacked a person or another animal before
- The owner had received complaints from neighbors about the dog’s aggression
- The dog had a pattern of lunging, snapping, or charging at people
- The owner kept the dog chained or locked away specifically because of its behavior
- The owner had previously warned others to stay away from the dog
The owner can be found liable for dog bite injuries if it is proven that they knew or reasonably should have known of their animal’s aggressive behavior. Any documented history — witness accounts, prior police or animal control reports, veterinary notes, or social media posts — can serve as evidence of that knowledge.
South Dakota also has a specific provision worth knowing: in cases where the dog chased, attacked, or killed another domestic animal such as another dog or poultry, S.D. Codified Law 40-34-2 holds the owner responsible for damages and costs stemming from the loss. A history of attacking other animals can also inform a court’s view of prior knowledge in a human bite case.
Exceptions and Defenses to the One Bite Rule in South Dakota
Even when you have strong evidence of prior knowledge, the dog owner may raise defenses that reduce or eliminate their liability. Knowing these defenses in advance helps you prepare a more complete case.
Provocation is the most common defense. Provocation means that the person injured by the dog aggravated, teased, or abused it, which caused it to attack. The exact definition of provocation usually depends on the facts of the case and rulings from previous legal cases. If the owner can show you provoked the dog, your recovery may be reduced or denied.
Trespassing is another significant defense. Victims who are lawfully on the dog owner’s premises — such as delivery workers, meter readers, and mail carriers — have the right to file a dog bite claim. If you were not lawfully present on the property at the time of the bite, the owner may argue they owe you a reduced or no duty of care.
Assumption of risk can also apply in certain situations. This defense argues that the injured person voluntarily and knowingly accepted the risk of being bitten. It is most commonly applied to individuals who work with animals professionally, such as veterinarians, dog groomers, and kennel employees.
Comparative negligence is the final major defense to understand. Most states use a comparative negligence system, in which a court assigns a percentage of fault to both parties. South Dakota follows comparative fault principles, meaning that if you are found partially responsible for the incident, your compensation may be reduced proportionally.
Important Note: South Dakota courts have held that the defense of assumption of risk does not apply where the victim had no prior knowledge of the danger the animal presented. If you had no reason to know the dog was dangerous, that defense should not bar your recovery.
Dog Owner Liability Beyond the One Bite Rule in South Dakota
The one bite rule is not the only legal framework that can hold a dog owner accountable in South Dakota. Several additional avenues of liability exist, and they can apply even when the classic one bite rule standard is difficult to meet.
Local ordinances can create independent grounds for liability. In many jurisdictions, including South Dakota, statutes and city ordinances have replaced the one bite rule. Municipalities and dog owners alike should pay close attention to the South Dakota Supreme Court’s opinion in City of Onida v. Brandt. If a local leash law or dangerous dog ordinance was in effect and the owner violated it, that violation may support a negligence per se claim — meaning the breach of the ordinance itself establishes negligence without further proof.
Breed-specific legislation is notably absent in South Dakota. South Dakota 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. This means a dog’s breed alone cannot be used as evidence against an owner in court.
Dangerous dog designations can escalate an owner’s exposure significantly. If the owner fails to properly restrain a dog after an attack and the dog attacks someone again, they may be considered negligent and liable for any resulting damages.
The recoverable damages in a successful dog bite claim in South Dakota can include medical expenses, lost wages, pain and suffering, and other noneconomic losses. For a sense of how South Dakota’s approach compares with a neighboring state, see our guide on dog bite laws in South Carolina, which operates under a different liability framework.
South Dakota also has a defined window for filing your claim. According to South Dakota Codified Laws § 15-3-530, claimants generally have up to three years from the date of the attack to file a claim. If your claim is filed beyond the statute of limitations, your case may be dismissed. Do not wait to begin the process.

What to Do After a Dog Bite in South Dakota
The steps you take in the hours and days following a dog bite directly affect the strength of any legal claim you may bring. South Dakota’s one bite rule places the burden of proof on you, which means evidence collection starts immediately.
- Seek medical attention right away. Get your injuries treated and documented, even if they seem minor. Medical records are among the most important pieces of evidence in any dog bite case, and prompt treatment also reduces the risk of infection or complications.
- Report the bite to local animal control. Filing an official report creates a formal record of the incident and triggers an investigation. Animal control may already have records about the dog — records that could establish prior knowledge on the owner’s part.
- Document everything at the scene. Photograph your injuries, the location where the bite occurred, any fencing or restraint failures, and the dog itself if it is safe to do so. Collect contact information from any witnesses.
- Gather the dog’s history. Ask animal control whether the dog has any prior bite reports or dangerous dog designations. Speak with neighbors who may have witnessed prior aggressive behavior. This evidence is central to proving prior knowledge under the one bite rule.
- Preserve all records. Keep every medical bill, prescription receipt, and documentation of missed work. These records form the foundation of your damages calculation.
- Consult a personal injury attorney. The provisions within South Dakota’s one bite rule can make it difficult for dog bite victims to receive just compensation if they try to seek damages without the legal counsel of an experienced personal injury lawyer. An attorney can evaluate whether a scienter or negligence theory is stronger given your specific facts.
South Dakota’s one bite rule can feel like a significant obstacle, but it is not an insurmountable one. A documented history of aggression — even without a prior bite — can be enough to establish the prior knowledge that triggers liability. The key is acting quickly, preserving evidence, and understanding the legal framework before the three-year statute of limitations runs out.
