No, Maryland does not follow a simple “one-bite rule” that gives a dog owner one free bite before liability can apply. If a dog causes personal injury or death in Maryland, the law may create a rebuttable presumption that the dog owner knew or should have known the dog had vicious or dangerous propensities.
This means a dog bite victim may not need to prove that the dog had already bitten someone before. However, the dog owner or insurance company may still raise defenses, such as trespassing, criminal conduct, or provoking the dog.

|---|---|---|
| Does Maryland give a dog one free bite? | No. | A prior bite is not always required for liability. |
| What is the legal standard? | Maryland uses a rebuttable presumption when a dog causes injury or death. | The owner is presumed to know or have reason to know the dog was dangerous. |

| Can the owner defend the claim? | Yes. | Defenses may include trespassing, criminal conduct, or provoking the dog. |
| Should you contact a lawyer? | Yes, especially if there are injuries, scarring, infection, or disputed facts. | A lawyer can protect your claim and deal with insurance. |
What Is the One-Bite Rule?
The one-bite rule is an old legal idea that may protect a dog owner from liability unless the owner knew or should have known the dog was dangerous. Despite the name, the rule does not always mean a dog literally gets one free bite. It usually focuses on whether the owner had notice of the dog’s dangerous behavior.
Examples of notice may include a prior bite, growling, lunging, chasing people, attacking another animal, or repeated complaints about aggressive behavior.
Does Maryland Follow the One-Bite Rule?

Maryland does not follow a simple traditional one-bite rule. Under Maryland Courts and Judicial Proceedings §3-1901, evidence that a dog caused personal injury or death creates a rebuttable presumption that the owner knew or should have known the dog had vicious or dangerous propensities.
The dog owner can try to rebut that presumption, but the injured person does not automatically lose the case just because the dog had never bitten anyone before.
What Is a Rebuttable Presumption in a Maryland Dog Bite Case?
A rebuttable presumption means the law starts by assuming something is true, but the other side can present evidence to challenge it. In a Maryland dog bite case, if a dog caused personal injury or death, the law may presume that the owner knew or should have known the dog was dangerous.
The dog owner may try to show that they had no reason to know the dog was dangerous. For example, they may argue that the dog had never acted aggressively before. However, the victim may respond with evidence such as prior complaints, witness statements, leash-law violations, aggressive behavior, or animal control records.
Can a Dog Owner Be Liable for the First Bite?
Yes. A dog owner may be liable for a first bite in Maryland, depending on the facts. A prior bite is not always required. If the dog caused personal injury or death, Maryland law may presume that the owner knew or should have known the dog was dangerous.
The claim may also be stronger if the dog was running at large, if the owner violated leash or animal-control rules, or if there were prior signs of aggression.
What If the Dog Was Running at Large?
If a dog was running at large and caused injury, death, or property loss, the owner may be liable under Maryland law unless an exception applies. This can include situations where a dog escaped a yard, ran loose in a neighborhood, or attacked someone in a public area.
Evidence such as photos, animal control reports, witness statements, leash-law violations, and prior complaints may help prove that the dog was not properly controlled.
Maryland Dog Owner Responsibilities

Dog owners in Maryland must take reasonable steps to control their dogs and prevent attacks. Depending on the situation, this may include using a leash, securing a fence or gate, obeying local animal-control rules, and warning others if the dog has shown dangerous behavior.
If the owner fails to control the dog and someone is bitten, knocked down, or otherwise injured, the owner may be responsible for medical bills, lost wages, pain and suffering, scarring, infection treatment, and other damages.
When Can a Dog Owner Avoid Liability?

A dog owner may raise defenses if the injured person was trespassing, committing a criminal act, or teasing, tormenting, abusing, or provoking the dog. The owner may also try to show they did not know and had no reason to know the dog was dangerous.
Because these defenses depend on the facts, it is important to gather evidence quickly after the attack. Photos, witness statements, medical records, animal control reports, and prior complaints about the dog can all matter.
How Contributory Negligence Can Affect a Maryland Dog Bite Claim
Maryland follows contributory negligence in personal injury cases. This means the insurance company may try to argue that the injured person’s own actions contributed to the injury. In a dog bite case, the owner may claim the victim provoked the dog, ignored warnings, entered a restricted area, or acted unsafely around the animal.
These arguments can make a dog bite claim more complicated. A Maryland dog bite lawyer can help review the facts, gather evidence, and respond to insurance defenses.
Can a Dog Owner Face Criminal Charges?
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. Criminal penalties are separate from a civil injury claim.
A civil claim focuses on compensation for the injured person, such as medical bills, lost wages, pain and suffering, scarring, infection treatment, and emotional trauma.
Can a Landlord Be Liable for a Tenant’s Dog Bite?

A landlord may be liable in some Maryland dog bite cases if the landlord knew a tenant’s dog was dangerous and failed to take reasonable steps to protect tenants, visitors, or others in areas the landlord controlled.
This often matters when the bite happens in a common area, such as a hallway, stairwell, parking lot, laundry area, sidewalk, or shared yard. For more information, read our guide on whether a landlord can be liable for a tenant’s pit bull attack.
What Evidence Helps Prove a Dog Bite Claim?
Helpful evidence may include medical records, photos of the bite wound, photos of torn clothing, animal control reports, witness statements, prior complaints about the dog, leash-law violations, vaccination records, insurance information, and proof of lost wages.
If the dog had a history of aggression, prior bites, repeated escapes, growling, lunging, or complaints from neighbors, that evidence may help show that the owner knew or should have known the dog was dangerous.
What Should You Do After a Dog Bite in Maryland?
- Get medical care right away, especially if the skin is broken.
- Report the bite to animal control or the proper local authority.
- Identify the dog owner and get contact information.
- Ask whether the dog has vaccination records.
- Take photos of the wound, torn clothing, location, and dog if safe.
- Get names and contact information for witnesses.
- Keep medical bills, prescriptions, and follow-up records.
- Avoid giving a recorded statement to the insurance company before understanding your rights.
- Speak with a Maryland dog bite lawyer if the injury required medical treatment, stitches, surgery, infection care, scarring treatment, or time away from work.
