I would answer with a question --

why are you mating your dog at all?

Is she a show champion? Does she have all her clearances (like x-rays for OFA hips, elbows?, CERF for eyes, genetic test for PRA, thyroid tested, patellas, VonW, to name a few?)

Is she a well known search and rescue dog, or perhaps a champion sheep herding dog?

Are you a member of the parent club and regional club of her breed? Have you signed an ethics agreement?

If the answers to these questions are "No", you should not have bred your dog the first time.

Also, if you were working with a reproductive vet, as you should be for your dog's safety when breeding, you'd already have the answer.
