Please be very careful. I had a similar experience like you did. These 2 puppies were free. They told me they were just too busy with their jobs and needed a loving home for them. They asked me many questions and told me they only ask me to send them pictures of them. So it sounds so much like yours

Please be careful!!!!!!!! There are alot of scams out there and I feel that this may be a scam for you also. These people list these 2 puppies all over the place and many people responds to them. And they seem to ask the same questions and give the same reason why they are giving them for free. Just Be Careful
