: I have an 8 week old maltese puppy who is just adorable.  She is very playful and the housebreaking is going great.  The only problem is she wines, cries and screams if you leave her alone.  Namely this is problem when we try to sleep at night.  We thought she would cry herself to sleep, but after 2 nights of 50+ minutes of crying, we are at a loss.  She only stops if we come and get her.
: Please help a very tired couple!  Thank you in advance!
