I read about people who have their dogs in an x-pen type setup when they are away, or unable to monitor the dog constantly.
First, let me make sure I'm clear on this....the difference (besides size) between leaving a dog in a crate, and leaving a dog in an x-pen, is that they are supposed to train NOT to go to the bathroom in the crate, right? And I assume that you can give them that option in an x-pen with pads or what have you, if you want?
If that's correct, my question is....what is the difference between leaving them in an x-pen (with food, water, pads, bed, or whatever you want), and shutting them in a small room such as a bathroom, or large closet, with all of the same, if the room is doggy-proofed?
Just asking because I don't see that referenced as much.
AND (this slightly bizarre question just occurred to me!

), has anyone ever trained their dog to get in the TUB to use their pads or litter box?! Seems like any necessary cleanup would be so quick and easy that way!
