Is it possbile that you misjudged her due date? You should have been counting from the first tie, but if she didn't actually take until a tie in the days following, then she is right on time.
From the behavior you described--loss of the plug, sticking to her whelping box and a change in her eating, it sounds like it is getting close. Monitor her closely and make sure that her whelping box is in a private, calm area. I'm not sure what you are feeding her now, but she will need plenty of energy for whelp. Try maybe hand feeding her some boiled chicken or something. Good luck! |
