I've been waiting to see if Kiki would develop that cutest of yorkie traits, "smiling". But Mazie is the one to surprise me with it!
She was nine months old when we got her, and is over a year old now. And she has just starting "grinning" when she greets us at the door when we come home!
Mind you, her "grin" looks more like a grimace, like she's having a fit or something

, not like some of the cute yorkie smiles I've seen pics of here

....still, it's so funny to see her little teeth flashing when she is all jumping around and wiggling and excited to see us!
Love these girls sooooo much!
