I am just a bit confused, and I'm sorry, but do you have 2 litters or 1? I was just asking because your other posts said you had a litter of 5 and then you had a litter of 4 . . so I'm assuming you have two litters? Are there any other animals in the house that can get to the puppies besides their mother? Is there the male or another female? A cat?
Not sure the mama would bite their own puncturing a hole . . .
