Pet breeder laws and pet purchase laws are different in each state. Contact your local or state regulated agency that oversees such matters, even the local SPCA may be able to get you to the correct "authorities" to help you. If a program is available that oversees such breeders (i.e., licensure, accreditation) you might be able to quickly resolve this issue by getting that agency involved. You can also directly inform the breeder (better in writing) that you have filed a complaint (if you did) and see if that will help speed things along to have your money returned to you. Now, there is a component of attachment as well. This is a living creature and it would be wise to think about whether or not you intend on keeping this animal or finding suitable adoption for this animal. The reason I say this is because if this should go to small claims court, the court may inquire about your intentions with placement odf the dog.
