Sandy, who is half Yorkie and an older dog who we rescued sleeps in bed with us, under the covers, by my feet. I think it's a security thing with her. Every time she naps or sleeps, she has to have a blanket covering her. We tried the crate with her but she really didn't do well, and since she is 100% potty trained, I don't mind that she doesn't use it. BUT when I get my Yorkie puppy it will be crate trained from day one. All of my other dogs have been and it really makes potty training and many other things easier for the dog and for ME
