Quick update --
It seems that, as several of you suggested, she is teething. I took her kibble and placed it in a ziplock baggie. Then I smashed it with a rolling pin (typical alpha male that I am

). I put that in her food dish and then sat down with her by her bowl. She came in just to see me

and then sniffed her food dish. I encouraged her by saying "good girl" and then she started eating. Once she realized that it wasn't painful, she wolfed that food down! I was so happy I almost cried (NOT typical alpha male behavior

). So a BIG thanks to all who offered suggestions (especially about smashing her dried kibble) and that teething might be the cause of the problem. I'll certainly be better prepared when we bring "Lollipop," her new baby sister home in a few weeks.
Good grief. . . I'm going to be knee-deep in the Yorkies! But, they are just sooo cute!
My wife says it's the best present I ever got her.
