Wow! You really got called in on a tough situation. I can't say that in your shoes I wouldn't have done the same thing. You would have always worried about her if you had let her go to some shelter. That being said, really, I mean *really* think about what you are getting ready for. I am glad to see that you have already taken her to the vet and got things like that lined up but emergency procedures can be costly. Then, there is the proper care of her and her puppies should everyone make it through okay. I just added a second to my family and it certainly makes an impact financially. That was just doubling my cost, not adding 3 or more.
I just hate to see well-meaning individuals get in over their head and have regrets about things they should've have done.
It is obvious you want what is best for her.
This is just so scary to me, and I live on a farm.
I have witnessed many births of livestock but these little creatures are like babies to me. I have read so many whelping stories gone bad that I could never go into it as uneducated as I am. I am not meaning this negative toward you, just sounds so scary to me.
