I just saw this on the Cesear Milan puppy mill special...AND it just happened to be a yorkie!! go figure! All he did when the pup started to go for the face was the "shute" thing that he does and gave him a little jab in the neck. He said NOT to pull your face away.(can't remember why though) I have 2 little lickers..Lillie is worse than Sadie. If I tell Sadie no or stop she will..Lillie doesn't pay attention to those words!! So I tried the "shute" and little jab..she did stop but then started again. I don't mind a little "kiss" once in a while but she doesn't stop! I just figure they love us! LOL
