Summary

In the City of Lawrence, pets don't need microchips as a general rule, but Section 3-502(g)(7) forces every owner whose animal is convicted of being a dangerous animal to microchip it and register the microchip information with the city clerk within ten days of conviction, alongside photographs, spay/neuter proof and a training class.

(7)Microchip. All owners of dangerous animals must, within ten days of conviction, microchip the animal and provide microchip information to the city clerk to register the animal as dangerous.

Full Breakdown

Section 3-502(g) sets the standards a dangerous-animal owner must meet once a court convicts the owner and the animal is allowed to return home. Paragraph (7) requires the owner to microchip the animal within ten days of conviction and provide the microchip information to the city clerk so the animal is registered as dangerous, part of a package of ten-day deadlines that also covers two identification photographs under paragraph (6), spay or neutering under paragraph (8) if the animal isn't already sterilized, and enrollment in a court-approved training class to be finished within 60 days under paragraph (9).

Outside this dangerous-animal context, Section 3-306(a) mentions a microchip only as one way an impounded stray's owner can be identified for notice purposes, and the chapter imposes no general microchipping duty on ordinary pet owners. The microchip and photo requirements travel with the dangerous-animal designation itself: if the owner later sells or moves the animal outside the city, Section 3-502(g)(10) requires notifying the city clerk, who reports the dangerous designation to the animal's new city.

Violations & Fines

Failing to microchip a dangerous animal within the ten-day window is a separate violation under Section 3-502(i), which the chapter's enhanced fine schedule in Section 3-103(d)(1) punishes with a fine of not less than $75.00 and not more than $1,000.00, up to 180 days in jail, and the municipal court may order the animal removed from the city or humanely euthanized for noncompliance.

Frequently Asked Questions

Does Lawrence require all pets to be microchipped?
No. The code has no general microchipping requirement for dogs or cats. Microchipping only becomes mandatory under Section 3-502(g)(7) for an animal a municipal court has convicted its owner of keeping as a dangerous animal, and that owner has ten days from conviction to chip it and register the microchip with the city clerk.
What happens if I don't microchip my dog after it's declared dangerous?
It is a separate violation of Section 3-502(i), on top of the underlying dangerous-animal conviction, punishable under Section 3-103(d)(1) by a fine of $75.00 to $1,000.00 and up to 180 days in jail. The municipal court can also order the animal removed from the city or humanely euthanized for failing to comply.
What else must a dangerous-animal owner do besides microchip the animal?
Within the same ten days, Section 3-502(g) requires two identification photographs filed with the city clerk and spaying or neutering if the animal isn't already sterile, plus a court-approved training class completed within 60 days and, in some cases, proof of liability insurance of at least $500,000.00.
