I think the greenish goo probably came from her bottom. Her stomach may have gotten upset before going into labor. I just saw it on her potty pad and kinda freaked out because I wasn't sure where it came from. I never actually saw the green goo coming from her vagina. Just a tan-ish yellow colored goo. :::sigh of relief:: One of the puppies came out butt first and I thought he was gonna get stuck but he came right out! She was so miserable from having all of those contractions for so long that she was biting her blanket and growling at it! I thought she was gonna kill the blanket lol.
All four boys are all nursing well and seem to be doing well. Duckie is a wonderful mother and does not like to have her puppies taken away! I will post pics as soon as I get a chance. Thanks everyone for your help and advice!
