Sorry, but still objecting to #2. Of course, you may get their credit card number when they purchase the puppy as that may be the means of payment, but what I am wondering is how that will allow you to contact them in the future. Will the credit card company give you my personal information if I move or decide not to continue my relationship with you? Will the fact that you haven't heard from me or my pup give you enough reason to subpoena or otherwise obtain personal information about me? Sorry, although it may be very noble of you to want to go to any means to keep in contact with your pups, I think the people purchasing the pups have to be entitled to certain privacy safeguards.
