This breeder is breaking the law and if anything happens to this puppy you won't be able to do anything about it...this is not a reputable breeder so I would be very nervous of the health of this puppy.
Have you been to her house? How did you find her? How do you know mom died? How old was mom? How many litters did she have? How many other dogs does this breeder have?
