How to stop my min pin puppy from barking

Question
I have a 10 week old min pin pup. When my room mate and I are not home, we place the puppy in a room that we have set up for her, complete with toys, dog bed etc. The problem is that when we place her in her room she will bark and bark and bark. We do not spoil her by holding her and treating her like a baby, so I don't think her behavior is a result of that. How can we get her to not bark when we leave her.

Answer
She is quite young, and still has to get used to accepting the crate.  I suggest covering the crate with a blanket so it is dark.  If you are leaving you can put the radio or tv on.  Give her things to do in the crate like bones, stuffed kong, treat balls.  

As she gets a bit older, you can teach a quiet command, this is done by first teaching speak command, then rewarding the dog when they stop barking while you say "quiet".  You can also correct her for nuisance barking, with a pinch to the scruff (like the mother dog does) and a "No", after that just the verbal "no" (or whatever word or noise you want to use) should stop her.  I hope that helps.
