St. Lucie County, FL Animal Ordinances: Breed Restrictions (2026)

14, and all later amendments defining and regulating dangerous dogs, by reference for the unincorporated county, and sets the annual dangerous-dog registration fee by resolution of the board of county commissioners. The public safety director classifies a dog as dangerous after investigating a sworn complaint if it has aggressively bitten, attacked or severely injured a person; has more than once severely injured or killed another domestic animal off the owner's property; or has chased or menacingly approached a person on a public street or sidewalk when unprovoked.

A dog cannot be declared dangerous if the injured party was trespassing or tormenting the dog, or if the dog was defending someone from an unjustified attack. The owner gets written notice of a 'sufficient cause' finding and seven calendar days to request an administrative hearing, held within 21 days; a final classification can then be appealed to county court within ten business days. Within 14 days of a classification becoming final, the owner must obtain a certificate of registration showing current rabies vaccination, a secure enclosure with warning signage at every entry point, and permanent identification such as a tattoo or microchip, renewed annually.

Outside the enclosure, the dog must be muzzled with a substantial chain or leash under a competent handler's control at all times; hunting dogs and dogs in legal obedience, conformation, field or herding events are exempt while so engaged, though a dog already classified dangerous can never be used for hunting. If a previously classified dangerous dog bites or attacks again without provocation, the owner commits a first-degree misdemeanor and the county impounds and, after a ten-day hold that allows an appeal, humanely destroys the dog.
