SLCRO §611.200 prohibits dogs, cats, puppies, and kittens from being at large anywhere in St. Louis County. Pets must be on a leash, in a cage or building, in a car, or on the owner's property at all times — this applies countywide, including all 88 municipalities.
Chapter 611 (Thermo-Animal Control Code) enforces the leash law countywide. Animal Control officers (north line at Page Avenue) catch at-large animals and check for tag/microchip ID. The county operates two shelters: Central (77 Hunter Rd, Ladue) and North (4100 Seven Hills Dr, Florissant). Reclaim fees, vaccination proof, and citations apply.
County ordinance violation; impoundment fees plus daily boarding. Repeat at-large offenses can trigger 'dangerous dog' designation under §611.220 with mandatory enclosure requirements.
