There are puppy lemon laws in most states and the magnuson moss consumer warranty act also applies in all states, IF a warranty was given. The FL unfair and deceptive practices act applies to consumer transactions too.

The so-called "puppy lemon law" is here: http://www.flsenate.gov/Laws/Statutes/2012/828.29 Whether or not you have a cause of action under the law I can't say. I suggest you speak with an attorney regarding your options.
If we do not have a signed fee agreement I am not your attorney and this is not legal advice.
The analysis begins with the contract. Did you sign a written contract and what is specifically provided under that contract? Did the breeder specifically exclude certain warranties? If you did not sign a contract, then warranties still apply. You need to consult with a local attorney.
This is not to be construed as legal advice. I do not have an attorney client relationship with you.
