Maryland Dog Bite Laws

Updated October 13, 2026 · 2 min read · 3 sources

Short answer

Maryland uses a hybrid rule (Courts & Judicial Proceedings 3-1901). Evidence that a dog caused injury creates a rebuttable presumption that the owner knew it was dangerous, and an owner is strictly liable if the dog was running at large, unless the victim was trespassing, committing a crime or provoking the dog. The deadline is 3 years.

Maryland has a dog bite statute, but it only covers certain situations; other cases follow traditional common-law rules.

What Maryland law says

  • Courts & Judicial Proceedings 3-1901 creates a rebuttable presumption that the owner knew of the dog's dangerous propensities (MSU).
  • If the dog was running at large, the owner is liable regardless of knowledge, subject to the listed defenses.
  • Anyone may kill a dog seen attacking a human, with immunity (LG 13-105).

Strict liability vs. the one-bite rule

The statute imposes liability only in the situations it lists. Outside those situations, injured people rely on the common law: showing the owner knew or should have known the dog was dangerous (the "one-bite" rule) or that the owner was negligent.

Dangerous dog rules in Maryland

  • Maryland Criminal Law 10-619 addresses dangerous dogs.
  • Counties such as Carroll, Frederick, Cecil and Washington have authority to seize dangerous dogs or dispose of vicious animals.

Deadline to file a claim

Justia's 50-state survey lists 3 years as the general personal injury deadline (statute of limitations) in Maryland. The clock usually starts on the day of the bite. Different deadlines can apply to claims against a government agency or on behalf of a child, so confirm the deadline for your situation with a licensed attorney.

What to do after a dog bite

  1. Get medical care, even for a small puncture; bites can become infected.
  2. Get the owner's name, contact details and the dog's rabies vaccination status.
  3. Report the bite to local animal control or the health department; many places require it so the dog can be observed for rabies.
  4. Photograph the injuries and the location, and write down witness names.
  5. Keep medical bills and records of missed work, and talk to an attorney before signing anything from an insurer.

If you own a dog that has bitten someone, follow any confinement order from animal control, keep the dog's rabies vaccination current, and consider working with a trainer or behaviorist. Leash rules are covered in Maryland leash laws.
