I had the same thing happen to my Chihuahua. Obie is the sterotypical Chi. He barks at everthing that makes noise or moves, to the point I have spoken to a Vet and a trainer for help. One day while I was out he must have barked non stop and made himself hoarse. For the following 2 days he barked but silently. His whole body would jump when he barked from his effort but not a peep.
Don't worry it came back, even thought some of my family hoped it wouldn't.
