If only one of us is in bed, then Allie is right up on the bed with her head on a pillow. If both of us are in bed, she's laying on the floor next to the bed. When I get up to go to work, Allie immediately jumps in and takes my place. When I sleep in on Saturdays, Allie starts whining around 5:00 am, because she's expecting me to give up my place for her!
During the day, while we're both at work, she lays on the bed because she has a clear view of the driveway so she can watch for us to return!
She has a crate that she rarely uses, but occasionally she decides she wants to be alone and will go in there to get away from all of the stress in her life (e.g. the vacuum cleaner).
