So my girls on her second litter, were in the last week...we know she’s defo having a litter and the puppies are nice and active, for the life of me I can’t remember  what she was like the first time round it was a couple of years ago now. But she has no discharge what so ever and I would of expected to see some by now surely in the last week. I know I should just relax and take it easy but it’s such an anxious time the last week isn’t it lol

Why are you expecting to see discharge?    You likely won't see anything at all until she starts labour.
