yorkiesmiles because my sweet Roxie will smile, if you ask her too.
She shows her teeth - it's soooo cute. She will even smile on her own - usually first thing in the morning or when I come home -- I need to walk in carrying the camera to catch her doing it, it's a riot.
She also does what I call her Elvis snarl - yep, she rolls up one side of her top lip - what a hoot.
