Johnson County, KS Animal Ordinances: Dog Leash Laws (2026)

Authority: K.S.A. 47-1701 et seq. (state dog laws), K.S.A. Chapter 19 (county authority to adopt animal control codes), and the Johnson County Code of Resolutions Chapter 10 (Animals). The Johnson County Sheriff's Office Patrol FAQ confirms that there is no county leash or tethering ordinance for unincorporated areas: owners are not required to keep dogs on a leash on their own property or in unincorporated public areas. However, the Sheriff's guidance states that if a dog is known to be aggressive, it is the owner's responsibility to keep it on a leash and prevent it from being aggressive to others — and Kansas common-law owner liability applies if a dog bites or causes injury. Johnson County is one of several Kansas counties that requires rabies vaccination for dogs, cats, ferrets, and horses; the Johnson County Department of Health and Environment investigates animal bites and works with local animal-control officers and Community Service Officers on rabies-exposure cases. Inside the cities, leash rules differ sharply: Overland Park requires dogs to be on a leash no longer than ten feet at all times when not confined to a cage, residence, or backyard; De Soto and Edgerton each have ordinances requiring dogs to be leashed; Olathe, Lenexa, Shawnee, Mission, Leawood, Prairie Village, Roeland Park, and other cities each maintain their own leash and at-large ordinances. Always confirm whether your address is inside city limits.
