Duke started sleeping with us the third night we had him. He would cry so much in the crate(in our room) no one was getting sleep. I started with him between my pillow and a big body pillow so he didn't fall off. He was only 2lbs. Now at 7 mos and 7 pounds he still sleeps with us. Most nights he sleeps on top of my hubby's legs..lol
It's amazing how much bed one small dog can take up.
