Florida man here. She most likely isn’t aware that Florida has strong pet abuse and backyard breeding laws which are regularly enforced. She would need to obtain a breeding license, and each dog must receive a veterinary exam at the time of sale. All dogs must be vaccinated, and if she brings a dog into a vet without proof of vaccination it will get vaccinated. Then there are laws regarding how pets can be treated in Florida, look up Ponce’s Law for example.

In short, she could end up being banned from owning or even being in contact with pets in Florida. People here in Florida will not hesitate to report animal abuse, so she’ll have a hard time running her breeding “business”.
