Nassau County, FL Animal Ordinances: Pet Store Rules (2026)

Nassau County Code § 18½-4 prohibits two categories of transaction: any retail sale of a dog, cat or rabbit from a commercial establishment (defined to include pet stores), and any retail sale of a dog, cat or rabbit from a public thoroughfare, public common area or flea market. 27's grant of animal control authority and describe documented links between pet-store puppies and substandard 'puppy mill' breeding facilities identified by the Humane Society of the United States, noting Florida had the highest number of consumer complaints nationally about sick mill-sourced puppies.

The exemptions are specific: animal shelters, local breeders (who sell from the county property where the animal was bred and reared, in zoning and animal-control compliance), and licensed animal welfare organizations are all carved out, and a commercial establishment may still showcase adoptable animals owned by a shelter or welfare group and collect an adoption fee passed through to that organization, so long as dogs shown that way aren't kept overnight and no animal shown is younger than eight weeks. Any commercial establishment sourcing animals from a permitted source, and any local breeder, must post and maintain a certificate of source on each animal's enclosure identifying breed, color, age, weight and the animal's original source, and produce it on demand to a law enforcement or animal control officer. Falsifying that certificate is itself a separate violation.
