Summary
Johnson County's Code of Resolutions does not single out any dog breed. Its dangerous-dog rules in Sec. 10-58 and Sec. 10-62 apply based on a dog's conduct: unprovoked attacks, bites, or fighting history, not pedigree. Any dog meeting that behavioral test in unincorporated Johnson County must be kenneled, leashed, and posted with warning signage regardless of breed.
Dangerous dog means any dog that demonstrates one or more of the following types of behaviors:(1)Any dog who is known to its owner, or reasonably should be known to its owner, to have a propensity, tendency, or disposition to attack without provocation, to cause bodily injury, or to otherwise endanger the safety of human beings or domestic animals....(4)Any dog kept for the purpose of fighting or any dog trained for fighting. ... It shall be unlawful for a person to own a dangerous dog, except in accordance with the following requirements:(1)Dangerous dog confinement. All dangerous dogs shall be securely confined within a building or in a securely enclosed kennel or pen....(4)Control of dangerous dogs. No person shall permit a dangerous dog to go outside its kennel or building unless:a.The dangerous dog is secured on a leash no longer than four feet in length;b.A person has physical control of the leash and animal to prevent attack; andc.The dangerous dog shall not be leashed to inanimate objects such as trees, posts, or buildings, or left unattended.

Full Breakdown
Unincorporated Johnson County regulates dogs through Article III of Chapter 10, and the article's definition of 'dangerous dog' in Sec. 10-58 is written entirely around behavior. A dog becomes 'dangerous' if it has a known propensity to attack without provocation, bites a person or another animal without provocation off its owner's property, kills another dog, or is kept or trained for fighting. Breed, size, or appearance play no role in the definition, and the code carves out exceptions for dogs that bite a trespasser, defend against an assault, or work for law enforcement.
Once a dog is declared dangerous, Sec. 10-62 imposes county-wide confinement duties: the dog must be kept in a building or a securely enclosed, floored kennel or pen that meets applicable zoning and building rules, and it cannot be left on a porch, patio, or behind only a screen door. Outside its enclosure, the dog may move only on a leash no longer than four feet, held by a person able to control it, and never tied to a tree, post, or building. Owners must post a 'Beware of Dog' sign in letters at least four inches tall at the kennel or wherever the dog is kept.
A dangerous dog may be ordered destroyed by the county district court after a hearing if the owner has two prior confinement or control convictions, the dog poses an imminent public threat, or it has killed or seriously injured a person; owners may request a hearing under Sec. 10-65(c) before euthanization proceeds. Enforcement runs through the sheriff's office and its designated code enforcement officers under Sec. 10-59, and prosecutions are heard in county district court's codes court division. These rules reach only unincorporated Johnson County; Overland Park, Olathe, Shawnee, Lenexa and the county's other cities enforce their own separate animal codes.
Violations & Fines
Owning or failing to confine, leash, or sign for a dangerous dog is a Class D infraction under Sec. 10-60, carrying a fine of $50.00 to $100.00, with each day of noncompliance charged as a separate offense. Interfering with a sheriff's code enforcement officer or refusing to surrender an impounded dog is separately unlawful under Sec. 10-59(c)-(d). A dangerous dog that is not properly confined can also be seized, impounded at the owner's expense, and, if it caused great bodily harm or death, ordered destroyed.
