There is a leash law within the city limits of Anacortes. Any time a dog or miniature pig is off the owner’s property, it must be restrained by a physical control device (leash no longer than 15 feet or carrying cage). This applies to all sidewalks, streets, private property, beaches, schools, and parks (with the exception of posted off-leash dog parks).
Additionally, it is unlawful to allow a dog or miniature pig to roam, stray, or be away from the owner's property. If you let your dog outside into an unfenced yard, you will need to stay outside and supervise them.
