oh my, I can't even imagine being in that situation. I wouldn't want to breed any girls I have for someone else's sake. But yea, I wouldn't want to be responsible for all the medical bills for such a thing, either. It may be common in some cases of contracting, but it don't seem right. It'll be pushing it if the pup was given to family or a friend and expect it, but it's worse if it's someone that, for all intensive purposes, won't really have any or much connection with the breeder later on, otherwise.
I dunno, it would feel like handing your own little girl-child over to strangers to do whatever they want... and that just don't sit well with me
