Full Breakdown
Oneida County does not restrict pet ownership by breed; Chapter 23 defines a 'vicious animal' purely by conduct. 04(20) sets the trigger: an animal is vicious if, within any twelve-month period, it bites two or more persons or inflicts serious injury on one person in unprovoked circumstances off the owner's premises. 10(3) empowers that officer to declare the animal vicious, and the owner or caretaker is served the order personally or by certified mail. An owner who disputes the declaration may petition the Oneida County Law Enforcement and Judiciary Committee within 30 days for a hearing under Wis.
Stat. Chapter 227, and may further appeal an adverse determination to circuit court within another 30 days. 10(4) requires the animal to be confined indoors, or in a locked pen with chain-link fencing on all four sides, sides embedded at least two feet into the ground or set on a concrete pad, or otherwise confined by material strong enough to prevent escape. 10(5) requires the animal to be muzzled and leashed on a chain or leash no longer than four feet, controlled by the owner or an immediate family member at least 16 years old. 10(7) bars selling or transferring a declared vicious animal without disclosing its status.
Violations & Fines
Keeping a declared vicious animal unconfined on the property, or off-property without the required muzzle and four-foot leash, violates § 23.10 and is enforced under § 23.18 with a citation from the Sheriff's Office and a penalty set under § 25.04 of the General Code. Selling a vicious animal without disclosing the declaration under § 23.10(7), or tampering with a required warning sign under § 23.17(3), is also a separate violation.
