[carmen in nj]

a maiden bitch is a girl that is having puppies for the first time, sorry, sometimes I get carried away, LOL usually they don't know exactly what to do , if you are an inexperience breeder you can miss the not so expected hints of whelping, specially it sounds like you are both maiden, LOL do you have a mentor you can call?
I just read your last post she can be trying to empty her bowels, keep her close and don't let her go outside, I have heard of new mamas having puppies in the yard because they know they have to push but they think is poop and is really a puppy...
