I can only echo the replies here. I would urge you to talk asap to the breeder of your bitch, and seek their guidance.
There is a "morning after" injection, which could have been adminstered, and a call to the vet would have allowed you to make the decision not to allow this pregnancy to go ahead. In any responsible breeding situation it is up to the owner to plan a litter, not for "nature to take a course", and the owner to follow it.
I would assume that you will be planning to get your dog and bitches eyes tested and their hips scored once the puppies are here? You must point out that neither has been done if they aren't to any potential purchaser, of one of the puppies.
Any experienced breeder will tell you that a bitch can mate and can concieve late into her season. If your stud dog is an experienced dog then you should have known this, and you should have had facilities to keep them apart.
Perhaps you should join this group guest and then we could help in any way we can. I see you have already been in contact and had a reply.
If we seem critical, it is because we have the welfare of the breed at heart, but we also want to help you sort out this and hopefully prevent it happening again.
