Pennsylvania Dog Bite Laws

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

Short answer

Pennsylvania makes owners liable for the medical costs of a dog bite or attack without proof of prior viciousness (3 P.S. 459-502). If the bite causes severe injury, such as broken bones or disfiguring lacerations, full damages can be recovered under the Dog Law; otherwise broader damages follow negligence rules. The deadline is 2 years.

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

What Pennsylvania law says

  • 3 P.S. 459-502 covers medical costs from attacks or bites (MSU).
  • Severe injury is defined as broken bones or disfiguring lacerations requiring multiple sutures or cosmetic surgery (459-102).

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 Pennsylvania

  • Pennsylvania's dangerous dog provisions begin at 3 P.S. 459-502-A; a magisterial district judge decides whether a dog is dangerous.
  • Owners must register the dog and keep it in a proper enclosure: a secure, locked pen with sides embedded at least two feet in the ground if there is no bottom (459-102).

Deadline to file a claim

Justia's 50-state survey lists 2 years as the general personal injury deadline (statute of limitations) in Pennsylvania. 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 Pennsylvania leash laws.
