I responded to your p.m. . just in case you did not get it. Tearing up everything in her kennel, or in her path is the indication she is in labor now she is about to have the babies now. You are going to have to assist her perhaps. The kennel might be too small for her. Potbelly's generally have five to six babies. She is going to need plenty of room. It is going to be very messy. Be careful if she delivers in the kennel, if she gets startled, she can trample the babies being scared being a first-time mother. She is about to become a Sow. since you said at 11:30 last night in your p.m. this was going on. I am sure she is delivering right now. This is very exciting times for you. You will have your hands full. Good luck. I hope everything is well right now. Don't forget to post pics.
