Monroe County, FL Animal Ordinances: Microchipping (2026)

Monroe County Code Section 4-81(t) lists the mandatory care standards for any dog that has been declared dangerous. Alongside confinement in a building or secure enclosure with a warning sign posted, muzzling or caging whenever off the owner's premises, rabies vaccination under Section 4-64, and sterilization, subsection (t)(5) requires the dog to be implanted with a microchip. The owner must register that microchip with the national registry applicable to the chip, and must provide the microchip number and other identifying information to the animal control supervisor.

The county does not require microchipping of ordinary, non-dangerous pets anywhere else in Chapter 4; the mandate is tied specifically to a dog that has already been through the dangerous-dog determination process. Because the standards of care in Section 4-81 apply to all owners and caregivers of animals as a supplement to the rest of Chapter 4, failing to chip and register a declared dangerous dog is treated the same as any other Chapter 4 care violation and referred to code compliance for citation.
