Wow...sounds like she is on her way to becoming a mommy! Glad you have her out from under the dresser. Even if you were able to reach her, she may have had a pup under there with out you even knowing it cuz you couldn't see under there...could you? Anyway, the whelping box is a much better place for her to be...or at least a place where you can readily assist if need be. Good luck....I'll keep checking in.
