I needed to add that whenever he does growl at someone, you as his leader should step toward him looking into his eyes, one finger held in the air or pointing directly at him and say in a very low, unexcited tone "Uh oh" or "no", whatever word you use to let your dog know he has stepped over a boundary. Hold that position with your body leaned forward, finger up or pointing at him, eyes boring into his and stare him back, just like an alpha dog or wolf would do in a wild setting. Difference is a wolf would use his body language, a stare and a low growl or bared teeth to show the offender he was stepping out of bounds. Hold your ground until the moment he breaks attention, looks away, backs off, then just go about your business instantly. The very instant he gives in, you back off and all is over and done with. He will learn that the growl is what causes this uncomfortable moment and associate the natural rebuke with an unhappy leader and also learn that the moment he backs off, it's over. Together with the NILIF program and a good behavior modification positive reward training program you can do at home, he should shape up nicely.
