Years ago, we moved house at a very inopportune time.
I had a brand new litter on the ground, just a few days old, and there was no pushing ahead our moving date. So, I packed up the dam and her puppies, and put them into the ground floor bathroom of the new house, safely tucked into the bathtub, complete with a heating pad and loads of bedding. On the door, I put a LARGE, hand lettered sign that said “Dog inside – DO NOT OPEN DOOR!!!!!”.
You can probably imagine what happened.
