Dubuque, IA Animal Ordinances: Microchipping (2026)

Dubuque's animal code has no general microchip mandate for dogs or cats, but it authorizes microchipping as a condition the City Manager can attach to a dangerous-dog declaration. Section 7-6E-2(C) requires the written declaration naming a dog "potentially vicious" to state the animal's description, the owner's name and address, the facts supporting the declaration, the restrictions imposed, the penalties for violating them, and, "if the City Manager so determines, that the owner or keeper be required to have microchip identification implanted in the dog." The parallel vicious-animal declaration under § 7-6F-2(C) carries the identical authority: the City Manager may determine "that the owner or keeper be required to have microchip identification implanted in the animal" as part of that declaration's contents.

In both cases the microchip requirement is discretionary, decided case-by-case rather than applied to every dog citywide, and it travels with the declaration itself, meaning it stays in force until the potentially vicious or vicious designation is lifted through the hearing procedures in § 7-6E-2(D) or resolved through the vicious-animal process in § 7-6F-3. An owner who was ordered to implant a microchip and fails to do so is violating a declared restriction, which is enforced the same way as the confinement and notification duties tied to the same declaration.
