I don't have my Yorkie yet but my Shih Tzu sleeps with us at night. Lately though he's been sleeping with our daughter in her bed. Sometimes he'll sleep on the couch. I slept with him from Day One and he had several accidents in the bed. I'm hoping with Lolly I will be strong enough to crate her at night until she's housebroken. Knowing me, I won't be able to do it, and I'll end up with pee in the bed again.
