Both of my dogs are barkers, but we try to keep them from barking AT people when they come in the door. My older dog seems to not be able to control himself, so, before he runs to the door to "greet" you, he will go and find his favorite toy and put it as far into his mouth as he can and then run at you with muffled barks (totally not something we trained him to do). The younger one has started doing this now too. Little crazies.
