The barking won't stop!

My Sassy is a 3 lb yorkie and love of my life (I'm sure you all can relate).  3 days ago we experienced a tragic accident.  I was walking her when a neighbor's 50+lb dog attacked her.  (he was off a leash)  I grabbed her up in my arms and twisted around away from the dog, but it came around and bit her.  After hitting the dog to get him off my little one, I ran inside.  It all happened so quickly.  I was so upset.  I took Sassy to the vet and it seems all is okay with no damage.

Problem:  SHE WON'T STOP BARKING NOW!!!  I always took pride in the fact i thought i had the only non-"yappy" little dog, but since the attack 3 days ago, she will not stop barking.  Even before the attack she knew "quiet" and would stop immediately.  Now she just ignores me and keeps yapping.  I'm sick of hearing her bark and now a neighbor has now complained of her barking while i was at work.  WHAT DO I DO???  WHEN WILL SHE STOP? :-(
