In the first few days apart from ensuing all pups especially smaller ones get enough milkbar time and stay warm, make no herculean efforts to save unviable pups, as inevitably something is found to be wrong as the pups develop (or in their case fail to).
If they have made it to the time the bitch starts staying out of the whelping box, any small ones may get the odd extra feed on theit own or a top up, but prefer to avoid the latter.
