You may start by requesting your neighbor to put his dog on a leash and do the same for yours as well. Dogs that attack other dogs also have a tendency to attack humans so you may need to consult a dog expert after agreeing with your neighbor.
Talk to your neighbor about keeping the dog away from your dog, put yours on a leash and get some pepper spray. The affects of pepper spray are only temporary, but the dog learns a valuable lesson. As a last result, call the pound and make sure that you report that it is being aggressive to other dogs.

If it's trying to attack your dog through a common fence, lay down some strong pepper to dissuade him from coming near. You may have to put up a block wall. If your neighbor owns the home, he'll be responsible for half the cost. If he doesn't want to pay you can put a lien up against his home because the block wall unjustly increases the value of his property.
If the dog is loose, most cities have ordinances against this. Call your local Animal Control and let them know a loose dog is trying to attack other dogs. They'll give the owner a warning to keep their dog contained or on a leash. If they continue to get called, they confiscate the dog and (hopefully) find it a good home with a good owner. But don't kick the dog - you could provoke it further - use pepper spray instead.
If the owner is letting this happen, have a friend video tape it. Turn it into Animal Control. If he's not a responsible owner, he shouldn't own a dog.
You have every right to feel safe in public areas and to walk your dog without the threat of the neighbor's dog attacking yours. You need to take action before something tragic happens - like the dog kills yours.
