Wow. Just read this thread. Just incredable that a breeder would breed such a young female and then sell it without knowing if it was pregnant or not!!
If she had any kind of breeding experience she had to have known.
I would not pay her a cent. Unless you plan on selling these pups as show prospects why bother getting the papers for them at all? Do you know how to evaluate a show prospect? They usually need to be at least 5 to 6 months old to estimate what quality they
may turn out to be. Why not find them good homes and sell for a few hundred dollars just to make sure the people will value the babies. The money is not as important as making sure they have perfect forever homes but you do need to charge them at least a few hundred dollars for them. Many breeders sell puppies without breeding rights for $800.00 to $1500. If you charged $400 to $500 for these little dolls it would be more than reasonable considering how much time and effort you put into raising them. Maybe you would want to keep one for yourself. Maybe you have friends or family who would want one. I'm sure you will find perfect homes for them if you do a great interview process.
