Summary
Florissant does not require microchipping for pets generally, but once the Director of Public Works declares an animal dangerous under Section 205.260, Section 205.270 requires the owner to have it permanently microchipped and to give the Health Department the chip number.
The owner of an animal that has been declared a "dangerous animal" shall be subject to such requirements as may be imposed by the Director of Public Works or the hearing board through written notification to the owner, including, but not limited to, the following: ... All owners of dangerous animals must ... have their animal microchipped for permanent identification and provide the Health Department with the microchip number.

Full Breakdown
260, not to dogs and cats generally. 270(A) lists the conditions the owner must meet, and item 11 requires that all owners of dangerous animals have their animal microchipped for permanent identification and provide the Health Department with the microchip number. The same subsection layers on a full set of other dangerous-animal conditions: a ten-day rabies quarantine if the animal bit or scratched a person, a brightly colored orange collar and tag, mandatory notice to the Health and Police Departments if the animal goes missing or attacks, a locked outdoor enclosure at least five feet by ten feet by five feet set back at least ten feet from any property line, a warning sign visible from the street, spaying or neutering within fourteen days, a $100 annual registration fee, and proof of at least $100,000 in liability insurance.
An owner has fourteen calendar days from notification to comply with all of these requirements, including the microchip. An animal can be declared dangerous for biting without provocation, chasing or menacing a person, being trained for fighting, or having a known propensity to attack, and the owner can request a hearing before a board made up of the Director of Public Works and the Health Supervisor.
Violations & Fines
Failing to microchip a declared dangerous animal, or to meet any other Section 205.270 condition within the fourteen-day compliance window, is punishable under Section 100.080, up to a $1,000 fine or three months in jail, and the animal can be seized and impounded for a minimum of ten days or until the owner shows compliance, with the owner responsible for kennel fees.
