outsmarted by a dog

wombat is very smart. she's a bit manipulative too. the last 2 nites we've had the same problem (and i think its going to become routine if we don't do something about it right away-- just not sure what yet). so around 9:30-10pm she settles on her bed for the nite. i go and shower somewhere between 10:30 and 11pm. after i get out of the shower (or last nite it was while i was in the shower) she gets up and moves to our room. i call her out and try to settle her on her own bed. she absolutely refuses to go on her bed. she'll lay on the floor and do a nervous wag, she'll roll over on her back in a submissive position but we can't get her to lay back on her bed. she'll keep trying to sneek out of the room and we'll find her curled up on zac's dirty clothes pile. by the time i'm tired of trying to settle her on her own bed and i wanna go to bed we're ready to give up. even though zac's still in the lounge room she doesn't want to be there and definately doesn't want to be on her bed in there. both nites we've ended up moving her bed onto the floor at the foot of our bed and she crawls on it right away and goes to sleep. she uses her cute dog looks to get us to give up on trying to order her around and allow her to sleep in our room! we could just be really firm and close our door but the first nite it happened she'd had a bad experience on her before bed walk with zac (they ran into a few cats who freaked her out and zac ended up smacking her to get her to quit focusing on them-- don't think that helped in the long run). now she's figured out the nite time routine and how to sway us to let her sleep in our room. we'll see how we go tonite.
