Nebo sleeps on my bed, he is allowed up there with permission. He didn't "earn" that right until he was older...I can't remember when, I think he was at least 2 years old (I would have let him up earlier, but my parents said no dogs on the beds at the time). He started out crated in my room for about a year, then allowed loose in my room at night, then of course, eventually the bed. I also have a 4 month old pup and she is crated in my room at night. I would not start out having a young pup sleep in the bed, nothing against anyone who does that, I personally just would not do that.
