How the law determines liability for dog bite injuries

On Behalf of | Sep 23, 2026 | Personal Injury

Dog bites in Prince George’s County can cause serious injuries and raise immediate questions about legal responsibility. Maryland law addresses these cases through strict liability, negligence principles and defenses that can limit or block recovery.

Maryland law can impose strict liability on dog owners

Under Maryland law, an owner may be liable for a dog bite even without proof that the animal showed aggression before the attack, as long as the legal requirements for strict liability are met. The focus is often on whether the injured person was lawfully present and whether the dog attacked without provocation.

General information on dog bite liability rules in different states can help explain the broader legal background, but Maryland applies its own standards to notice, provocation and owner responsibility.

Negligence can also matter when notice becomes important

Even if strict liability does not fully resolve the case, negligence may still matter. In that setting, the injured person may need to show that the owner failed to act with reasonable care to prevent a foreseeable injury.

Animal control reports, prior complaints and other records may help show whether the owner had reason to know the dog posed a risk. Courts and insurers often look closely at that proof when deciding whether the owner should have taken preventive steps.

Common defenses can block recovery entirely

Maryland follows the contributory negligence doctrine. If the injured person’s own conduct contributed to the attack, that finding can block recovery entirely. Common defenses may include:

  • The injured person provoked the dog
  • The injured person was trespassing
  • The injured person knowingly approached a dog showing warning signs

That is why the factual record matters so much. Witness accounts, photos and records from the scene may all shape whether the injured person can recover at all.

Early records can affect both liability and damages

Liability and damages often turn on the same early records. Medical bills, wage loss and proof of pain and suffering may support the damages side of the case, while incident details and the dog’s history may shape the liability analysis.

People dealing with broader premises liability and injury issues may also need to consider how Maryland’s rules on notice, defenses and contributory negligence fit together. The earlier those facts are documented, the harder they are to dispute later.
