Hi - I'm Midwoof, Cindy. The best thing you can do for her right now is to calm down
. Let her know you are there but be discrete. DO NOT break the sack. I have had them showing for a couple of hours. My vet tells me if they are NOT pushing hard or they aren't in any distress then chances are things will be ok. BUT..... if your vet says bring her in then I'd be out the door.
There are some really great experienced breeders here who will be able to provide some fantastic info.
