It is confused about who is in charge. It is quite possible it is used to
Being in charge, and intends to stay in charge. Likely it is already neutered,
But do so now if not. Dogs with behavior problems should never be bred. Then
You need to take over as top dog. Having a good pack structure reduces such
Problems. The dogs see all the
People and dogs in the household as a pack with each having their own rank in
The pack and a top dog. Life is much easier if the 2 legged pack members
Outrank the 4 legged ones. You can learn to play the role of top dog by
Reading some books or going to a good obedience class. A good obedience class
Or book is about you learning to be top dog, not the dog learning it gets a
Treat if it sits. Start at
Raising Your Dog with the Monks of New Skete.
A top dog does not put up with biting by a lower status one. Give a warning
Stern "Bad Dog!". In
Stubborn cases, I repeat the "Bad dog!" right in its face with the dog on its
Back. Hold it down until it lifts one back leg to show submission. Use one
Forearm under his jaw to keep his teeth away from your face. If you can't do that,
Try the squirt bottle. Fill it with water and a little vinegar or lemon juice. Give it a
Squirt in the face as soon as it misbehaves. Dogs hate that. Every time he snaps or
Growls, he immediately gets which ever bad consequence works best for you.
Don't forget the praise and petting when he finally yields.
If you bought him from a breeder, let the breeder know you are unhappy with his
Aggression. It is absolutely wrong to breed aggressive dogs. If the dog does
Not respond to discipline, you may have to destroy him. Let everyone else know
Where you got the dog and the problems you are having. Breeders that breed
Aggressive dogs, should be run out of business.
I hope Buzz is still OK. Sometimes it is a little hard for you to tell the difference between play and aggression. Buzz can tell, and if he flees, it is a problem. Again, use the squirt bottle, if you don't have the size and strength to but him on his back safely.
If you get to where you may try to walk him again, try a head collar. There are 2 brands, for him I would favor the Haltie which does somewhat function as a muzzle over the Gentle Leader. The head collar dramatically puts you in charge without the jerking with the other collars or pain.
He could be beyond you due to poor breeding and early socialization. Most of his personality was formed before you got him. You may want to consider finding somebody that can handle him, and keeping Buzz. To find Shepherd loving people to take him and save him start at

For a rescue description, see
http://www.no-sb-260.com/rescue.html. If you can't change him, or find somebody that can, he may have to be destroyed. I usually do not suggest it, but this may be a case for Crazy's suggestion of hiring a trainer.
I am a former AskMe expert, and found a reference to this site on
www.pointask.com. I am active on several sites, but haven't found one I really like. I saw your older question, and answered it because I thought you needed help.
Late 07 update:
Although I have found the above advice effective, along with most of the dog training world, I have moved to more positive methods. I like the Top dog rules at
