King County, WA Animal Ordinances: Breed Restrictions (2026)

King County Code 11.04 (Animal Control) aligns with Washington state law RCW 16.08, which establishes behavior-based dangerous and potentially dangerous dog designations rather than breed-specific restrictions. RCW 16.08.070 defines a dangerous dog as one that has inflicted severe injury on a human, killed a domestic animal without provocation, or been previously found potentially dangerous after aggressive behavior. Washington state does not permit municipalities to enact breed-specific legislation (RCW 16.08.090 preempts breed bans). Pit bulls, Rottweilers, Dobermans, and other breeds sometimes targeted in other states are not restricted in King County. Dangerous dog designation requires muzzling in public, secure enclosure at home, 250,000 dollar liability insurance or surety bond, microchip, and registration with King County Regional Animal Services. Violating dangerous dog conditions is a class C felony if the dog attacks again. Landlord and HOA private restrictions on breeds are separate from county code and enforceable as lease or covenant terms.
