I suppose it is not an impossibility to find a good dog on craigs list. There are so many economic problems going on right now in this country that dogs are losing their homes at a record level. As people lose their homes so do their pets. Of course there are always the people who think they want a cute little fashion statement dog and then find that they actually have to do stuff for the dog so they re home the poor thing. Craigs list is the fee ad board. It attracts all kinds.

American Kennel Club - Club Search and Directory
There are several breed conformation clubs in Florida but I did not see one right in Jacksonville. Years ago I purchased a little Maltese from a show/breeder in Jacksonville. The puppy was going to be shown but her nose color was not quite what it needed to be to be a winner. These clubs usually have breeder contact people to write to and they will let you know about any reputable breeders that they know of. You can also go to the YTCA website and contact Florida breeders listed on that site. Even if one person does not have puppies they might know another breeder that does. It takes some searching.
