with all the dogs, why would you breed a female who is incapable of caring for her litter? Some of the issues can be inherited. Accidents are another issue, but to have a female where you automatically know she can't raise the litter, why??
lots of breeders take at least a week or so off work when they have a litter of pups so they can keep an eye on them. She isn't laying on them to KILL the pups, but because she just hasn't learned to be a good mom yet. Once the pups are 2-3 weeks old they will be able to move out of her way.
