You have been thru some stuff lately, and it is not near over yet, is it? Bless you...you're an angel.
You cannot really predict an animal's behavior when having offspring. My first Shep/Lab, who was my baby girl, begged to go 'potty' outside in mid-winter...to welp pups in the snow.
I found her having the 3rd and we took everyone inside to the welping box for the last 4, and warmed the first 3 pups up in my sweater. My second Shep/Lab, who was also my baby girl, dug an underground den. One feral kitty had her kittens in a folded tarp. Another feral kitty jumped up on our CA King waterbed, laid down in my husband's armpit
and went directly into labor, delivering 4 live kittens and 1 stillborn. I fetched and carried, especially layers and layers of soft towels from the welping box.
I hope all goes well...for all concerned. You deserve a break in the action!
