We’ve been at it 12 hours now with periods of long rests interrupted by heavy panting and shivering. River is a trooper. I let her out of the whelping box for two meals (scrambled eggs for breakfast and cottage cheese for lunch) and several potty breaks. After lunch she was so eager to get back into her whelping box that she jumped in before I could open the door for her. She’s started having a slight brownish discharge which must mean puppies are getting nearer but it could still be many hours to go. She has not yet started actively pushing so we are still in Stage 1 labor near as I can tell.
