Welcome to YT! I am so sorry that your little one is so sick.

I'm glad that you have taken her to the vet and she is being treated. My suggestion would be to follow your vets advice and keep a close eye on her. Someone else also suggested that you contact her breeder to help with the bills and I think that is also a great suggestion that you should follow up on. There are laws that protect the buyer an many states and I believe FL is one.
I'm wondering if you actually saw the parents of your puppy. Many times it is not a breeder but a broker selling puppies. Could you give us a name or website of where you purchased your little one from.
Please do not feed her ham.
