I kind of have one like that. She does not chase animals, but when people drive into the yard she has to bark and run over to greet them,..
When I call her name and tell her to "shut up" she does. When I call her to come to me (when there are people in the drive) She looks at me as if to say " I hear you, I know what you want, I have decided to stay here instead".
I think the meter reader has caused this to occur. She gives them a "treat" when she is reading meters so she think everyone might give her a treat.
