I let Lola sleep with me. She has a doggy bed for the living room(because she likes to nap during the day, I don't get that luxury with two boys
At night she sleeps in my bed. First couple of times I'd panic during the night trying to find her tiny body but she was always ok, just somewhere under the covers. I like having her close to me and I think it makes you "bond" more with your puppy. At puppy kindergarten though, I was the only bad owner who lets their puppy sleep with them. I didn't care though, I know she's spoiled and I wouldn't have it any other way. According to the dog trainer, they should be crate trained and NOT sleep in your bed...who could resist that cute face though?
