Please do. Dogs get up and move around a LOT during the night (or day). Don't take this the wrong way, I don't mean to be derogatory, but I think it's pretty demanding (in a control freak kind of way) to want to control where and how the dog sleeps. Your boyfriend needs to pick his battles. There's no good reason for him to dictate where she sleeps. There are going to be plenty of times when your dog needs to obey you, but this isn't one.I will talk to him about loosening up.
You're reading entirely too much into this and you're asking entirely too much of the dog. If the dog sleeps for 3-4 hours and then wakes up she doesn't automatically think of what your last command was to her and think, "I'm going to show them. I'm gonna go sleep in the bathroom." The dog wakes up and has no idea at all what your last command was. Doesn't have a clue. Doesn't know and doesn't care. If you want you can stand there right when the dog wakes up, give the command to sleep in that spot, enforce it if necessary and eventually you may be able to teach the dog to sleep only in that spot. Do you really want to stay up literally all night long for 2-4 weeks to do that?Our bathroom floor is tiled, but we have mats and she slept on it. We dont want her sleeping just anywhere in the house because we told her to stay in her bed so that's a command, and not listening (although she may forget over time...) and us not doing anything about it lets her in control. It's mostly just about us being her owner, not the other way around, so we don't want a power struggle that we lose.
I'll cast my vote for letting her sleep where she wants. It's one thing to insist that a dog not sleep on your bed, but it is not reasonable (IMO) to insist that the dog not move from her own bed all night. Why the heck would you care?However, if a lot of people tell me that I should just let it be (I'm more lenient than my boyfriend, it's more of his rule) I will talk to him about loosening up.
