Some states have statewide dog leash laws. These laws are referred to as "running at large statutes." Many states do not have statewide leash laws, but counties, cities, towns, and municipalities have laws that determine when a dog must be leashed and not "running at large." These leash laws sometimes require dogs to be registered and wear an identification tag.
In Pennsylvania, there is no statewide leash law that applies to all areas. However, the state has a 'running at large' statute that prohibits dogs from running at large in any place other than the premises of the owner or under the reasonable control of some person. This means that while there isn't a specific statewide leash requirement, dogs are not allowed to roam freely without supervision or control. Local ordinances in various counties, cities, towns, and municipalities within Pennsylvania may have their own specific leash laws. These local regulations often stipulate when and where a dog must be leashed, and they may also require dogs to be registered with the local government and to wear identification tags. Dog owners in Pennsylvania should check the specific leash laws in their local area to ensure compliance.
