I'm loving all the Yorkie timeclock stories! 
Here's a typical scenario:
Mom's on the computer. It's 6:01 pm. Bella (usually it's her, sometimes it'll be Tuffy) will come sit at my feet. If I take no notice of her, she'll get up on the couch beside me & whine a little. If I STILL don't get up, she'll put up her front paws on my arm so that I HAVE to stop.
Now, when they're eating, that's sometimes fun too. Bella gobbles her food down literally. Tuffy likes to take his time. I think it's from us free feeding him for the 1st year or so. Some days it'll take him 20-30 minutes to eat & I'll admit to getting a little impatient. So I'll say "Momma's gonna pick it up". INSTANTLY, his head is in the bowl!
Mornings, Bella is awake & ready to eat at 7 am. She'll paw my head if I don't get up. I've learned to sleep under the sheet!
Tuffy knows when his Dad is coming home even before I do. I think he hears the semi truck. Or the motorcycle.
OK, story time's over...off to sew!
