What does your Yorkie KNOW for certain? As in something your Yorkie never forgets?
Yoda knows where his food and water is, where his toys are stored (hallroom closet), where he sleeps (Mommy and Daddy's bed, though I think he considers it his own), who to beg for food when they are eating (Mommy and Grandpa), the sound of Mommy's car and the garage door, and who will let them be licked by him (pretty much all close family members).
I'm sure there is tons of others, this is all I could think up for certain for now.
