Lakewood, CO Animal Ordinances: Microchipping (2026)

Lakewood Municipal Code § 6.05.030(A) governs the mandatory conditions a Municipal Court must impose after a conviction, guilty plea, no-contest plea, or deferred judgment on a dangerous-animal possession charge under § 6.05.020. Item 2 requires: "The owner shall, at the owner's expense, have a microchip containing an identification number implanted into the animal and provide such information to the Animal Control Section of the Police Department. The owner shall produce the animal for verification by animal control of the microchip implementation." Animal Control must keep records of the registration number, the animal's name, and the owner's name and address, and the owner must report any change in address, ownership, or the animal's death.

The microchip mandate sits alongside a full set of court-ordered conditions in the same subsection: spay/neuter at the owner's expense (item 1), an escape-proof, locked, inspected enclosure (item 3), a ban on keeping the animal where it could exit on its own (item 4), a six-foot secure fence or supervision by an adult 21 or older when outdoors (item 5), muzzling and a four-foot non-extension leash off the owner's property (item 6), an eight-by-ten-inch "BEWARE, DANGEROUS ANIMAL" sign at every property entrance (item 8), and current rabies vaccination under § 6.04.010 (item 15). A near-identical microchip mandate applies to animals judicially declared "aggressive" under § 6.05.034(A)(1), a separate, lesser classification from "dangerous."
