A lot of people with dogs with this problem would probably also start the Nothing In Life Is Free program on the aggressor - check them out on Google and read several of them - they are all free programs and very, very easy to do. This will start to show him that you are his leader and he needs to heed your every word in order to get his needs met. Keep your commands anger or force-free and stay matter-of-fact during the training and get him a bit under control. At the same time, start him on basic obedience and work faithfully at it daily and always positively with him. Keep it upbeat, fun and be very enthusiastic when training him so he will love love love working and learning. He'll knock himself out for you that way. Of course, never punish a dog during training because they don't do what you request, just say "uh oh", wait 30 seconds and retry with a smile on your face. Short, repetitive sessions which are lots of fun and positively rewarding will begin to pay off with a dog learning how to control himself and his impulses. And, he'll learn that you are his valued team member but that you are also the coach and GM, too, and what you say goes.

Walk with a bag of juicy treats suspended from your waist. You will have taught him to sit and "Watch me" already as part of basic obedience so when another dog starts to approach, tell him to sit and "Watch me" and use food if you must at first to keep him focusing on that as the other dog walks by. If he does rise, take him on his leash and walk him in circles for a time using the food treat or a squeaky toy as a lure in your right hand as you turn him while the dog passes but only do that if he rises himself. Otherwise, you want him seated during the walkby and focused on your and/or the food in your hand. Once the dog is safely past, sit him again if he rose and you circled, praise and treat and resume your walk. If he stays seated during the pass and watches you the whole time - WOW - you are really getting there. Gently praise him(not too much so as not to excite him) and give a nice treat and immediately start back walking.

Until he is older and has better impulse control and respect for you as his leader, keep the dogs separated when treats, chewies, food and even toys are out. Once he is really under your control and can always obey you, then you can relax some of your hard and fast rules and see if they can play with a few toys together, etc.

Always rebuff fighting with immediate separation, taking him from the room and leaving him in a closed room for about 15 minutes until he is calmed down. Later, when he's really trained, a fight can still happen between dogs as it even can with people, say "No!" in a low, guttural voice, use a claw-hand on the back of his neck pressing in somewhat to mimic the discipline of an alpha dog or a mother dog, hold him in place until he is calm and then remove him from the room. When placing him in the other room, meet his eyes and lock them and show by your body attitude and face that you are displeased with his behavior. Do not speak to him when you are emotional after the fight except to say the "No!" when the fight starts. Leave him in the room at least 15 minutes or until he is well settled down and then reintroduce him into the room, allowing the dogs to resume their relationship.

Further, train your little aggressor to allow your other dog to romp around in his presence. Put him in a Down, Stay and have treats. Gently play with your other dog and every so often, as long as he stays down and quiet, give your boy a treat. Over time and with repetition, this will desensitize him to accepting that your other dog is going to be playful and bouncy around him and he has nothing to say in the matter. If he tries to rise or growl, say "uh oh" and immediately remove him from the room for 15 minutes of quiet time. No less time than 15 minutes. If he's whining or barking, increase the time for 15 minutes after he has quieted down. This will help him learn that getting quiet will keep his time-out to 15 minutes but that raising a ruckus will increase it. In time, he will learn to quiet himself and wait for his release.
