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 Massachusetts, there is no statewide leash law, commonly known as a 'running at large statute.' Instead, leash laws are determined by local ordinances and regulations. Cities, towns, and municipalities within Massachusetts have the authority to enact their own leash laws, which typically specify when and where a dog must be leashed. These local ordinances may also include requirements for dog registration and the wearing of identification tags. Dog owners in Massachusetts should check with their local government to understand the specific leash laws applicable in their area. Failure to comply with local leash laws can result in fines and other penalties.
