I am so sorry about your puppy.
What state do you live in? Some states have tough "puppy lemon laws" that require a breeder to do more than replace a puppy or give a partial refund. Some require a breeder to pay for vet bills if the puppy has a genetic condition. A breeder must comply with the laws of the state she sells in no matter what her contract states.
I'd be happy to check the law in your state for you. |
