Sounds like he's just so glad you are home and he's no longer alone, he just can't help himself! I love all the Yorkie kisses but don't know how much your baby might be kissing and do know some dogs go overboard at times. If he is into licking obsessively, after what you consider an appropriate amount of kissing, say "uh oh" and gently push him back or stand up - whatever you need to do to make your face unavailable. He will eventually get the picture. Give him a kiss from Tibbe and me.
