Mine both sleep on the bed. Kiba as a pup cried all night, and it broke my heart and I caved and let her in the bed with me. Bad choice cuz she just wanted to play and would end up falling asleep on my head while chewing my hair. Stryder as a pup was crated the longest.. baddest puppy out of the two. As a puppy, I would stick Stryder on the bed to play with Kiba, kept him out of trouble. But he couldnt figure out the bed would end and he'd fall right off. And stupid me would put him back up and he kept falling off. One of the first nights he got to sleep on the bed, I woke up and couldnt find him. He had fallen off the foot down between my bed and a chest, and was just sitting there as quiet as could be waiting for me to rescue him. LOL.
Both are good now, and just sleep on the bed all night long. Sometimes Stryder will get up and sleep on the floor, but he's usually off and on all night. Recently with all the extra blankets on my bed they choose to camp out in front of the window all day. I'm going to get them a dog bed to put on MY bed so they can be extra cozey when keeping watch.
I was fine with a twin bed, but upgraded to a double so that they could have more room. I get 1/3.. they get about 2/3rds.. and they choose to take up my space! LOL.
