Summary
Dane County has no general pet-microchipping mandate, but ch. 47.18(9)(b) requires an owner whose animal has been declared dangerous to provide written veterinary proof that a microchip has been implanted before the animal can be kept under restrictions instead of destroyed. The microchip must carry specific warning language identifying the animal as dangerous.
(b) The owner must provide written proof from a licensed veterinarian that a microchip has been placed in the animal so that the animal can be easily identified. The microchip must contain the following information: 1. the name of the animal, 2. the name of the owner, and 3. the following language "Dangerous Animal, contact Public Health Madison & Dane County Animal Services at (608) 255-2345."
Full Breakdown
Once the Department of Public Health for Madison and Dane County declares an animal dangerous under sec. 18(7), the owner has 30 days to document compliance with the restrictions the department sets under sec. 18(9). One mandatory restriction, at (9)(b), is written proof from a licensed veterinarian that a microchip has been placed in the animal so it can be easily identified. " This sits alongside the chapter's other declared-dangerous conditions: proof of spaying or neutering at (9)(a), current rabies vaccination at (9)(c), compliance with license requirements at (9)(d), and posted warning signs at (9)(e) no smaller than 8 by 11 inches with lettering at least 3 inches high at every building and fence entrance.
Microchipping outside this dangerous-animal context is not required anywhere else in Chapter 47; ordinary licensed dogs need only a rabies tag and license tag on their collar, not an implanted chip. Failing to satisfy any restriction, including the microchip proof, keeps the animal ineligible to be kept and can lead the department to order it surrendered and impounded.
Violations & Fines
Failing to comply with a dangerous-animal restriction such as the microchip-proof requirement of ch. 47.18(9)(b) is a violation of sec. 47.18, which under ch. 47.51(10) forfeits not less than $50.00 nor more than $500.00. The department may also order the animal surrendered and impounded, or humanely destroyed, if the owner does not document compliance within 30 days of the dangerous-animal declaration.
