MI - Leash - 287.262. Licensing and control of dogs; hunting dogs; female dogs in heat; straying dogs
Summary: This section of the Dog Law of 1919 provides that any dog over six months must be registered and wear a collar at all times. It also mandates that female dogs in heat must be kept on their owners' premises or restrained on a leash. The overall leash requirement is less clear, stating that it is unlawful for an owner to allow a dog "to stray unless held properly in leash." This does appear to mandate a statewide leash requirement for dogs.
