Woooohoooo so happy Momma has made it thru...and when I looked at the pic of momma and babies I started crying, what a wonderful pic to see....and what beautiful babies you have
I would never ever let her go back to that owner never for no amount of money, those are your babies...they need you and you need them
I agree if your Vet said it was ok for her to nurse I would let her nurse...if he didn't think it was safe I'm sure he would have told you no...trust him he hasn't let you down yet and from the sounds of it he is not gonna..and from the looks of that pic she wants to nurse and take care of her babies...just remember she needs to be on a good puppy food 4 times a day feedings and get a calcium supplement from your Vet if he hasn't gave you one already.
Good job sweetie...hang in there...and {{hugs}} to you and lots of puppy kisses to momma and babies.
