Just heard some squeaking from the corner of the room and there's mum cleaning one tiny puppy. She's cleaned it up really well but although its squeaking she hasn't let it near her nipples, she's curled up in a ball now. Is this normal? How long before I should worry? Am trying to let nature take its course but what if she doesn't let it feed? Is it ok to help her?
How long should there be between puppies?
