Are Dog Owners Liable in Maryland? Strict Liability, Exceptions, and What the Law Requires
August 25, 2026
If a dog bites someone in Maryland, are dog owners liable in Maryland automatically, or does the victim still have to prove something first? The answer depends on where the bite happened, what the dog was doing at the time, and whether the person who got hurt did anything to provoke the attack. Maryland’s rules changed dramatically in 2014, and the state now uses one of the toughest liability standards in the country for dog owners.
This guide breaks down exactly when Maryland dog owners pay for injuries, what victims need to prove, and which legal loopholes can shift the outcome. You will also see how leash laws, insurance requirements, and county-level breed rules factor into the equation.
Pro Tip: If you are a first-time dog owner in Maryland, understanding your legal exposure before an incident happens is far cheaper than learning about it in court. Reviewing guides on choosing a dog breed suited to your household can help you avoid many of the risk factors discussed below.
Is Maryland a Strict Liability, One-Bite, or Negligence State
Maryland is best described as a hybrid strict liability state, not a true one-bite state. Maryland’s dog bite law underwent a significant transformation on April 8, 2014, when the General Assembly enacted Md. Code, Courts and Judicial Proceedings § 3-1901, replacing the older one-bite rule with a system that strongly favors injured victims while still allowing responsible owners narrow opportunities to defend themselves. That reform came after years of legal confusion following a controversial court ruling.
Under the current statute, the law presumes that the dog owner knew or should have known their dog had vicious or dangerous propensities, and the burden shifts to the owner to overcome this presumption with affirmative evidence that the dog had no history or signs of dangerous behavior. This is different from a pure one-bite rule, where a victim would have to prove the owner already knew about a specific prior incident.
A separate, harder-edged rule applies when the dog gets loose. Under Section 3-1901(c), the owner of a dog is liable for any injury, death, or loss to person or property caused by the dog while it is running at large. In that scenario, there is no presumption to rebut at all. According to Nolo’s legal encyclopedia, an owner is strictly liable for any injuries or property damage caused by their dog while it is running at large, and Maryland law doesn’t have an exact definition of “running at large.”
Victims are not limited to the statute, either. The state also allows victims to base their claims on other legal principles such as negligence, negligence per se, and other common law or statutory causes of action, just as owners can raise any other common law or statutory defense. That flexibility matters most in cases involving landlords, dog sitters, or kennel operators, where the strict liability statute does not directly apply.
| Liability Theory | When It Applies | What the Victim Must Show |
|---|---|---|
| Strict liability (running at large) | Dog is loose or not under physical control | Only that the dog caused the injury or damage |
| Rebuttable presumption (statutory) | Dog causes injury while not at large | Injury occurred; owner’s knowledge is presumed |
| Negligence claim | Non-owner defendants or gaps in the statute | Duty, breach, causation, and damages |
What a Victim Must Prove Under Maryland’s Rule
The exact burden of proof depends on which legal path a victim takes. When the strict liability statute applies, the process is fairly simple compared to older common law rules.
- Show the dog caused the injury or damage. Under strict liability, a victim does not have to prove that the dog’s owner did something wrong; as long as the victim can show that the dog injured them or damaged their property, the court will assume that the owner is legally responsible.
- Confirm the injury falls under the statute. Maryland’s dog-injury law covers all injuries inflicted by dogs, and there is no legal difference between a bite and, for example, an injury a victim suffers because a dog knocked them down.
- Establish ownership. The presumption of knowledge under the statute applies specifically to owners; a different, harder standard applies to landlords or caretakers.
- Overcome any rebuttal evidence. An owner can still try to prove the dog had no dangerous history, so victims benefit from documenting prior complaints, animal control records, or witness statements.
If a victim is pursuing a claim against someone other than the dog’s legal owner, the standard gets tougher. In cases against persons other than a dog owner, subsection (b) of the statute requires the dog bite victim to prove that the dog previously acted viciously or dangerously, and makes clear that proof must be something more than showing the dog was a pit bull. This matters in rental housing, where a landlord’s exposure hinges on what they actually knew.
You might wonder whether a victim ever needs to prove negligence directly. If the strict liability rule does not apply, victims may still pursue a negligence claim, which requires proving the dog’s owner failed to exercise reasonable care in controlling or restraining the dog, such as when the dog was off-leash in an area where leashes are legally required. That path becomes especially relevant in the leash-law section below.
Exceptions: Trespassing, Provocation, and Warning Signs in Maryland
Strict liability sounds absolute, but Maryland carves out real exceptions that can eliminate an owner’s responsibility entirely. The most common defense involves the victim’s own conduct at the time of the incident.
- Trespassing. A dog owner is not liable when his dog bites a trespasser, whether the trespass is intentional or inadvertent, under Bramble v. Thompson, 264 Md. 518 (1972).
- Committing a crime on the property. Owners are not liable when a victim is committing or attempting to commit a criminal offense against any person or on the property of the owner.
- Provocation. The statute also protects owners when a victim was teasing, tormenting, abusing, or provoking the dog. The DCMD Law blog notes that whether the victim provoked the dog is one of the most important factors that can exempt an owner from liability, particularly if the person teased, taunted, or otherwise triggered the attack.
- Warning signs and assumption of risk. Posted warnings can shift responsibility onto the visitor. In one Maryland case, a delivery man saw a sign reading “Guard Dog on Duty” but opened the office door anyway and was attacked; his conduct was deemed an assumption of the risk of injury, and he lost his case.
These exceptions do not disappear just because the dog was loose at the time. Even under the running-at-large rule, the owner is not responsible for injuries or property damage if the victim was trespassing or attempting to trespass on the owner’s property. That overlap often becomes the central fight in contested claims.
Comparative Fault: How Shared Blame Affects Liability in Maryland
Many states let a jury reduce a victim’s award based on their percentage of fault. Maryland does not follow that model. Instead, the state uses one of the harshest fault doctrines still on the books.
Maryland adheres to the ancient doctrine of contributory negligence, which does not permit a victim to recover if his own actions contributed even just one percent to the cause of the accident. In practice, this means partial fault does not just reduce a settlement, it can eliminate it entirely.
Maryland’s contributory negligence rule can significantly impact dog bite cases, and if the victim is found to have contributed to the incident in any way, they may be barred from recovering any compensation. A victim who ignored a “Beware of Dog” sign, reached into a fenced yard, or approached a restrained dog aggressively could see an otherwise strong claim wiped out on this basis alone.
Key Insight: Because contributory negligence is an all-or-nothing rule, insurance adjusters in Maryland often look hard for any evidence of victim fault before agreeing to pay a claim. Documenting the scene, witnesses, and your own conduct right after an incident matters more here than in comparative-fault states.
Criminal Liability for Dog Owners in Maryland
Civil damages are not the only consequence Maryland dog owners face. The state’s dangerous dog statute carries its own criminal penalties, separate from any lawsuit a victim might file.
Violating the dangerous dog statute is a misdemeanor punishable by a fine of up to $2,500, and this criminal penalty applies on top of any civil liability the owner may face for injuries caused by the dog. Owners whose dogs are formally classified as dangerous face strict day-to-day obligations. A dog designated as dangerous cannot be left unattended on the owner’s property unless confined indoors, in a securely enclosed and locked pen, or in another structure designed to restrain the dog, and it cannot leave the property unless leashed and muzzled or otherwise securely restrained.
Reporting requirements add another layer of compliance. If a dog bites a person, the bite must be reported to the local health department. Rabies vaccination is also mandatory statewide: Maryland requires all dogs to be vaccinated against rabies, and under Md. Code, Health-General § 18-318, owners must have their pets vaccinated by a licensed veterinarian and maintain current vaccination records.
Criminal exposure and civil liability run on parallel tracks. As Alex Poberesky’s law office explains, in some serious cases a dog owner may face criminal penalties if the dog is considered dangerous and the owner failed to properly restrain or control the animal, and criminal penalties are separate from a civil injury claim focused on compensation for the injured person.
Leash Laws and How They Affect Liability in Maryland
Leash rules in Maryland are a patchwork rather than a single statewide mandate, but they carry real weight in liability cases. While Maryland does not have a statewide leash law, most counties and municipalities require dogs to be leashed in public areas, and specific requirements vary by jurisdiction. Before letting a dog off-leash anywhere outside your own fenced property, check your county’s animal control code.
The connection to liability is direct. Allowing a dog to run at large triggers strict liability under Section 3-1901(c). An off-leash dog that gets loose in a park or neighborhood puts the owner in the toughest liability category the statute offers, with no presumption to rebut. Holman & Dickriede summarizes it plainly: Maryland follows a strict liability rule for dogs running at large, so if the dog was not properly contained or leashed and it bit someone, the owner can be held liable even without a prior history of aggression.
Leash violations can also support a standalone negligence claim, independent of the strict liability statute. If a county ordinance requires leashing and an owner ignores it, that violation can serve as evidence of a breach of the duty of reasonable care, feeding directly back into the negligence framework described earlier in this guide. Owners researching everyday tools for managing dogs safely in public may find value in tracking guides like the best apps for dog owners, several of which include leash-law reminders by jurisdiction.
Local Breed-Specific and Insurance Requirements in Maryland
Maryland’s approach to breed regulation has a complicated history. A 2012 court ruling imposed breed-specific strict liability, holding that anyone who knew or had reason to know a dog was a pit bull was automatically strictly liable for any attack, with no prior history of aggression or evidence of negligence required. That ruling triggered widespread disruption before lawmakers intervened.
The 2014 statute reversed course entirely. Maryland has moved decisively away from breed-specific regulations at both the state and local levels; at the state level, Section 3-1901 explicitly applies the same legal standards to all dogs without regard to the breed or heritage of the dog, a direct response to the earlier pit bull ruling. As LegalClarity puts it, the practical effect is that no dog breed receives special treatment under Maryland’s bite liability statute, so an owner of a Labrador and an owner of a pit bull face the same legal framework.
Local governments still have some room to legislate, though the trend is moving away from breed bans. At the local level, the most significant recent change occurred in Prince George’s County, where the County Council voted in November 2025 to repeal its nearly 30-year ban on pit bull breeds, with the new law taking effect in December 2025. Some jurisdictions still maintain their own ordinances, so checking county-level rules remains worthwhile before assuming state law is the only word on the subject.
Insurance coverage adds a separate wrinkle that has nothing to do with what the courts require. Most dog bite claims are paid through the dog owner’s homeowner’s or renter’s insurance policy, specifically the personal liability coverage, and standard homeowner’s policies typically provide between $100,000 and $300,000 in liability coverage, applying even when the bite occurs away from the owner’s home. The catch is that coverage is not guaranteed for every breed. Many insurance companies exclude certain breeds from coverage entirely, with pit bulls, Rottweilers, Dobermans, German Shepherds, Chow Chows, and Akitas commonly excluded.
Owners are entitled to know about these exclusions before a claim ever arises. Maryland law under Chapter 406 of 2013 requires insurers with breed-specific exclusions to provide written notice to policyholders identifying the excluded breeds. If you own one of the frequently excluded breeds, it is worth reading a resource like this site’s breed-specific liability and insurance guide before assuming your homeowner’s policy will cover an incident.
Pro Tip: Call your insurer directly and ask whether your dog’s breed is listed on their exclusion list. Maryland’s 2013 disclosure law gives you the right to that information before you renew or purchase a policy, not just after a claim is denied.
Maryland’s ownership rules extend beyond dogs, too. If you keep other animals alongside your dog, it is worth understanding how the state treats them separately; guides covering goat ownership laws in Maryland and hedgehog ownership laws in Maryland outline requirements that differ meaningfully from the dog-specific statute discussed here.
Filing deadlines apply no matter which theory of liability a victim relies on. Maryland has a strict statute of limitations for filing personal injury claims, including dog bite cases, and victims have three years from the date of the incident to file a claim. Missing that window generally ends any chance of recovery, regardless of how strong the underlying facts are.

Maryland’s dog liability framework asks a lot of owners: strict responsibility when a dog is loose, a presumption of knowledge even when it is not, and criminal exposure layered on top of civil damages. At the same time, the law gives owners real defenses through trespassing, provocation, and Maryland’s unforgiving contributory negligence rule. Whether you are a longtime owner or bringing home your first dog, understanding these rules before an incident happens is the most reliable way to protect both your pet and your finances.
