The Dog Bed

When we bought the girls their bunk beds we ordered a twin over a double. We decided it would be a good idea to have a bed big enough so the girl could sleep together. They have always liked to snuggle together, whispering secrets late at night. Holly changed the dynamics when she started sleeping in bed with the girls. Now whoever sleeps in the double bed gets to snuggle with the big furry dog.  
Since the bunk bed has been apart Holly goes back and forth between beds. The other night I woke up to some noise coming from their bedroom. I walked into their room to find Holly spread out on the twin bed. She had her head on the pillow and stretched nearly to the foot board. Did I mention she's a big dog?
The commotion I heard was the girls trying to convince Holly to get off the bed. The brunette twin explained that she got up to use the bathroom and found Holly spread out on the twin bed when she came back into the room. Holly wasn't interested in moving. She turned her head so she wouldn't see the girls trying to get her to move.
I told the brunette twin to sleep with her sister. On the one hand I didn't want to deal with Holly. It was late and I didn't want to fight with the dog. On the other hand I told the girls that once they let Holly sleep in their beds that they wouldn't be able to get her off the bed. Who knew Holly would eventually try to claim an entire bed for herself?
