I don't know about the Maltese but bichons are known for having poor teeth to start with, so if you aren't feeding properly and brushing her teeth, this 'may' be the issue. Check her mouth and see if she has lots of tartar build up on her teeth, especially the back molars.
But I'm still thinking she is a 2 meal a day doggie!
