My RB Little Dog (Yorkie) slept with me EVERY night that she could. She decided to sleep with me the first night (but at the foot of the bed cause, as she was previously abused, wasn't too sure of me yet). My dad discovered her the next morning and gave her *THE LOOK* (as he did not approve of dogs on the furniture). After a few nights of trying, and failing miserably , to get her to sleep in a dog bed, he eventually gave up and the rest is history.

My Chihuahua sleeps with me off and on. Sometimes she has to stay in the crate overnight when she has a potty accident at night. She is definitely a blanket tunnel maker.
