I've used the bath room as a kennel area before. You can help out making it a nice place to be by starting the pup off in there for other things before you do the leave for work thing. Like feed them, time out, nap time , while your home even use a baby gate instead of shutting the door at the start. You'll be home to teach them not to mess with the baby gate. The only thing I concern with pups or dogs ,, that if they are chewers not to leave anything with them that may be a choking hazard . And due to a story about a rotti sucking on a rubber toy with a small hole it getting his tongue stuck in it for the sucktion and it killing him.. Toy consideration for safety is always on my mind. I've video my guys when I was gone all they ever done was lay down and wait or look out the window : Never once play'd with anything...
