Linda, if you figure out how to get a Yorkie to be quiet for even 1 hour, I'll hire you as Ellie's trainer. lol.
I know it's hard, but try to relax. We have had so many scares with Ellie (could be abcdefg and what if it's cancer????? AND, AND), but she has always been okay. They just like to scare you once in awhile.
