House Bill 1521 introduces comprehensive regulations for dog breeding and the operation of animal shelters in Florida. It establishes Section 585.701, which mandates the Department of Agriculture and Consumer Services to create best management practices for dog breeders, ensuring humane treatment and ethical standards. The bill also preempts local oversight of animal shelters, requiring state-level rules for animal care, reporting, and euthanasia guidelines, while encouraging collaboration with nonprofit organizations to improve shelter management. Additionally, the bill amends Section 828.29 to enhance consumer protections in pet sales, requiring pet dealers to disclose financing terms, implement a three-day waiting period for financed transactions, and provide medical records to consumers.

Moreover, the bill removes the previous requirement for a veterinary inspection certificate for each dog or cat purchased from a pet dealer, instead mandating that dealers retain sales records for at least seven years. It establishes a registration framework for dog breeders, requiring a certificate that must be renewed every two years, and outlines specific care standards for breeding dogs. Violations of these regulations can result in civil infractions, fines, and potential criminal charges for severe cases. The bill emphasizes animal welfare and responsible breeding practices, aiming to protect both animals and consumers, and is set to take effect on July 1, 2026.
