In the Florida we have what is called the "Lemon Law", you can not sell a dog or cat without a state health certificate that verifies the dog has been seen 30 days or less before the sale. However, there is a loop hole to the law. The only way you HAVE to do this is when you have more then 2 litters of puppies or kittens per year that you sell.
The health certificates are detailed and include a vet exam, fist set of vaccinations, dewormer, and fecal check. Personally I would never buy a puppy without vaccinations or vet papers from anyone but especially a breeder. You're paying the price not only for the bloodline of the puppy but for their health as well. I personally don't see how a breeder is going to sell a puppy without proper vaccinations. In fact here in the states many breeders give the parvo vaccination to puppies when they are 6 weeks old and then follow up with the rest of their appropriate shots at 8 weeks old. They also deworm the puppies several times before they leave for their new home.
Is your puppy coming with any type of health guarantee or genetic guarantee? Is this breeder licensed? How long has she been breeding and why does she breed? Does she require a spay or neuter contract for non show puppies? How long has she been showing and handling the breed? What is her property like? Is it spacious, clean, and kennel free? Why did she pair the dam and sire together and why did she believe they would make exceptional puppies together that would better the breed standard? Are there any championships in the bloodline? What titles are in the puppies pedigrees? What are the strengths and weakness of her bloodlines? ALL dogs have these, be leery of "oh my dogs don't have problems"! What genetic testing has the dam and sire had and what were there scores and are the certificates available for viewing? Is she an active member in any dog clubs and is so which ones?
Anyone can claim they are a breeder but if they can not answer the above question properly then they are a backyard breeder trying to make a fast buck. A good breeder will also have a lot of questions for you, they won't settle on the homes their puppies go to because it's more then just money to them. Be careful, even those who come off as animal lovers and dedicated dog handlers sell sick puppies and inbreed. Be sure this woman is the real deal. Puppies are cute but make sure you've really hit all angles with this woman before taking one home - anything can happen and people lie. If she can not verify certain information then run for the hills.
