Oh My! Wow! That little dog and her puppies to be be are very lucky you found them! You are a wonderful person for taking her in and giving those puppies a chance. I have never seen a dog deliver but I have heard that they will stop eating and become restless. Why don't you contact your vet and ask him/her for some tips? Also, have the vet's number at hand should something go wrong in the delivery. Please let us know how it goes!
