Summary
Janesville does not ban any dog breed by name. Instead, Code § 8-43 lets police authorities kill any dog, licensed or not, that is known or reasonably believed to be mad, vicious or dangerous to the public, or that has bitten someone hard enough to draw blood, and § 8-45 separately bars a vicious dog or a dog or cat in heat from running at large.
Any dog found or being within the limits of the City, whether licensed as required by the ordinances of this City or not, which is known to be or which there is good reason to believe is mad, vicious or dangerous to the public, or which has bitten any person so as to cause a wound which bleeds, may be killed by the police authorities. ... Any person who interferes with an officer in the discharge of his or her duties under this section or who conceals any such dog shall pay a penalty as provided in Section 8-48.
Full Breakdown
Section 8-43 authorizes police authorities to enter private premises to find, take or kill a dog that meets the mad, vicious, dangerous or biting standard, and requires the dog's owner to allow the police to take and kill it and to render reasonable assistance; anyone who interferes with an officer under this section or conceals such a dog faces the penalty in § 8-48. The determination turns entirely on the individual dog's known behavior or an actual bite, not on its breed. Section 8-45 makes it unlawful for an owner to let a fierce or vicious dog, or a dog or cat in heat, run at large anywhere in the city at any time, with the same § 8-48 penalty attached.
A related but separate track covers rabies: § 8-44 adopts the state's rabid-animal isolation statute, Wis. Stat. § 95.21, and § 8-46 lets the City Council order all dogs confined, tied, leashed or muzzled during a rabies emergency; three days after the Council publishes that order, any dog still running loose and unconfined may be killed by a police officer.
Violations & Fines
Section 8-48 sets a forfeiture of $30.00 to $500.00 for a first offense, $50.00 to $500.00 for a second, $70.00 to $500.00 for a third, and $100.00 to $500.00 for a fourth or later offense, with up to 60 days' imprisonment if unpaid. Each occurrence and each day of continuance counts as a separate violation, and the City can also seek injunctive relief to stop it.
