Tracy, after making sure no more of the strange Two-Legs, hopped back up and looked around at the various metal boxes, wondering how the two-legger got them to move, but decided it didn't matter. Her mate, a former computer geek, had found her again, and had brought her a package of ground beef from the supermarket, she smiled and licked his face happily.
As they shared the beef, Tracy thought about all the human-dogs in the mall, she and her mate would need a new place without the competition to raise their pups safely, not wanting the larger males to harm them. After eating up the meat, she and her mate licked each other clean, and Tracy led him back to the changing room that's she was in when the change happened earlier.
"Back in my den!" Tracy thought as she laid down on her former clothes, her mate curling up and laying next to her. As they laid there happily, Tracy thought about the outside world, she had pictures and memories of it, but so much of it was blurred and unclear that's it was pretty much useless now. "Tomorrow we'll find a new den away from all these other packs." She decided, looking over at her mate, who was licking his crotch, she felt like that shouldn't be normal, but didn't know why.
In the outside world, things weren't as happy as Tracy believed, with humans being so numerous in the world, and dogs only having so large a population, modern infrastructure just didn't have the workforce needed to sustain it. Sure the dogs could keep a few towns running, maybe a city or two, but the wolves had no concept of modern society, and were the dog version of cavemen, not to mention that with humans replacing dogs and wolves as pack carnivores, it didn't bode well for the deer and other prey species.
But, Tracy didn't know this, she happily raised her tail for another round of mating, happily enjoying her life with her new mate, and couldn't wait to have pups! Curled up on her old clothes, the two slept soundly as the new dog/wolf civilizations worked themselves out, and the human-dogs formed the hierarchies needed for their pack society.
