◦ Summary
Washington has no statewide dog leash law. Leashing rules are set by individual cities and counties, and most municipalities require dogs to be leashed in public except inside designated off-leash dog parks.

◦ Notes & gotchas
Day-to-day leashing requirements live in city or county ordinances. Before relying on this page, look up the specific code for your municipality — it's the binding rule, not state law. Most US cities require dogs to be leashed in public unless inside a designated off-leash area. Seattle Municipal Code § 18.12.080 requires dogs to be on a leash no longer than 8 feet in public, with off-leash use permitted only in designated off-leash areas. King County and other Washington cities have similar rules.
