My girl has been in stage one all day. She just had a burst of dark green discharge. Iknow this is normal after a pup is born but not before they even started pushing. I have never seen this. Is this normal in anyone else's bitches? I have called the vet and was told to give it one more hour and see what happens and that this is normal. I thought that this meant a placenta was detached and the pup was in trouble.
