On Friday, the vet said that it would be best for Scout if we gave her system a break and go ahead and wean the puppies. I had been putting off removing the big box from the puppy pen because it provided a barrier between Scout and the pups when she wanted it, but now there was no reason not to give the pups more space.
So, we scooted the pups and their big box to the end of the pen and put the whelping box-turned-litter box in. Then we just lifted the big box up and over their heads and all of a sudden it was new world. I wish I had my phone handy so that I could have recorded the mayhem as they ran and tumbled all over the place - it was a hoot to behold.
