redhen, no, but what she is describing is NOT normal for a b.itch with puppies less than 21 days old. As Dainerra said, if you are going to have issues, it will be in the first week with sore breasts, etc. Up until at least 4 weeks, healthy normal b.itches nurse puppies whenever they demand it, and usually sleep at night in the box with the puppies. It is very unusual to have a b.itch not spending almost ALL of the time with the puppies until at least the end of the second week. Even with a large litter, normal b.itches feed puppies on demand AT LEAST until 3 weeks.
So one of two things are going on here:
Either this b.itch is just lacking in the natural drives to mother and raise her litter, or she has some health issue going on that is interfering with that.
