Your yorkie is soooooo cute love the ears!!! you jsut wait a few and he'll start barking. I got my yorkie when he was 7 months old and he hardley made a sound when i brought him home. But now if it's not me or his papa or grandparents he barks like crazy especially if i'm right there (I assume he's trying to protect his mama) Enjoy the peace and quiet while you can lol
