Are Dogs Permitted to Run Loose in Pennsylvania?

Pennsylvania’s Leash and Restraint Laws for Dogs

Pennsylvania law imposes strict requirements on dog owners to confine and control their animals. Dogs are not permitted to run loose or roam freely in most circumstances under the Pennsylvania Dog Law (3 Pa. C.S. § 459-305). Understanding these rules is important both for dog owners seeking to comply with the law and for injury victims seeking to establish liability after a dog attack.

What Pennsylvania Law Requires

Under Pennsylvania’s Dog Law, a dog owner must keep their dog either:

• Confined within the premises of the owner (inside the home, within a fenced yard, or in a secure enclosure), or
• Accompanied by and under the control of a responsible person when off the owner’s premises

A dog that is off the owner’s property and not under direct supervision and control is considered “running at large” — a violation of the Dog Law. Dog wardens and local law enforcement have the authority to seize dogs found running at large.

Local Ordinances in Erie

In addition to Pennsylvania’s statewide Dog Law, many municipalities — including the City of Erie — have their own leash ordinances that may impose additional requirements, such as mandating that dogs be on a leash of a specific maximum length when in public areas. These local ordinances work alongside state law and can be relevant in a dog bite case as additional evidence of an owner’s duty of care.

Why This Matters in Dog Bite and Attack Cases

When a dog that is running loose bites or attacks someone in Erie County, the owner’s violation of Pennsylvania’s restraint laws is powerful evidence of negligence. A dog that should have been confined or leashed but wasn’t — and that then injured someone — supports a finding that the owner failed to exercise reasonable care. This can strengthen a victim’s claim not just for medical expenses (which may be recoverable under strict liability) but also for pain and suffering and other damages.
