First you move very slowly and easy with the mom, do not attempt to touch the pups till you get her out of there, she will resist so be patient and be careful please.
Leash her or tempt her with s treat, move her away and be sure to hold on to her,get the pups out into a box, so they won't get chilled or dropped by accident, then walk slowly into the house, mom will follow.
Lay them down on a nice clean sheet with a blanket for comfort under it, she will go right to them, watch her and make sure she let's them nurse again, some moms not many will not want them to nurse after being touched by humans, but she should, very few do this.
Good luck and again be careful and gentle with her
Congrats on the new pups....what are you gonna name them
Curly, Mo and Larry, Just kidding have fun with the new kids
