Yorkie bad behavior

Question
Hopefully you can helpe me.  We adapted a 3 year old Yorkie male.  Although at first he seemed to be a well manored young man, as time has gone on his behaviors have gotten worse.  I can handle the occasional garbage messes and the accidental tinkles or poops on my floors.  However, he sleeps in my room constantly and even that is ok.

However, if my husband is not in bed first with me, and tries to come into the bed after i am settled, the dog attacks him viciously.  He recently bit my husband on the chin as he leaned in one morning to kiss me good bye.  Occassionally my 7 year old son sleeps with me and if my husband tries to move him off of the bed or kiss our son, the dog will also attack him.
What do we do?  We have tried crating him at night, but that is no use.  He barks relentlessly.  In a house with all hardwood floors, it can become so loud it is horrible.  We have even tried to lock him in the bedroom with our oldes daugter who is 10.  He simply just wants to be with me at all times.

Any advice on how to get back to a harmoneous household?
Thanks.

Hello..this dog is in the bed with you? That is not good..the dog can not sleep in the bed or he will take a dominant stance as he is doing. When you put him in the crate have you tried placing the crate in your room so he is nearby? he may bark a bit, but i think he may stop. Try this and tell me what happens..i will talk to you in a couple of days..thanks
