Establish dominance. Show your dog in no uncertain terms that this behavior will not be tolerated. To do this, use your cell phone to call your home phone or vice versa. Have your dog on a leash and when he starts to go "crazy", tug slightly on the leash to get his attention while simultaneously making a "psst" or "NO" noise. Also, take your thumb, pointer, and middle fingers and gently, but assertively, "bite" him at the throat. This simulates a bite from a dominate dog and eventually, he will become submissive. Do not do this so hard that your dog starts choking, that is not the purpose. It is a training tool that you should use each and every time that he does not exhibit the behavior that you deem as acceptable. We used this technique on an out of control pomeranian who always used to attack people when they would try to leave and now, he is very sweet and quiet. This will take some time, b/c there is no quick "cure" for bad behavior. Your dog wants to be good and please you, but you have to clearly assert your dominance and define the "bad" behaviors. Never praise him for calming down after a huge outburst when the phone rings, but do praise him when he doesn't have an aggressive outburst. If this technique doesn't work, I strongly suggest consulting a professional dog trainer, b/c the old addage "you can't teach an old dog new tricks" just isn't true. Good luck! I hope you find something that works for you!
