I have a 12-month-old Boxer who's dominant towards other dogs. I want him to be able to play and run at a dog park? Do you think this is possible?

I have a 12 month old Boxer (neutered) who is extremely dominant/aggressive towards other dogs. I have just watched your DVD on this matter and am anxious to start applying your techniques. I have a prong collar (which I found out I was putting on the wrong way) although he still accepted it well. I also just received the dominant dog collar from you. Here is my question. I am a small woman and my Boxer is about 55 pounds but seems like an elephant when he sees another dog. The prong helps but I still feel a bit behind the eight ball. It doesn't seem like I can get that level of correction needed that I see you apply in the DVD. I was thinking about getting a muzzle for our walks and saw that you have one that will be perfect for the Boxers head. If I muzzle my dog and we encounter another dominant/aggressive dog who has an untrained handler, am I not putting my dog at risk in a fight? I certainly could not stop a dog fight and wouldn't even try but if it got intense would I be really endangering my dog by cutting off his defenses? Would love to get your advice on this subject. My dog appears very well trained at home with the basic obedience commands but as you pointed out in your DVD, with his behaviour outside the home, he really isn't trained at all. I'm hoping I can overcome this because he really learns quickly and loves to please but just seems to be wired wrong when it comes to other dogs. By the way, I started him in puppy socialization classes at 12 weeks and he already was what I call a "psycho" He then went on to basic obedience (always being the class distraction and general pain in the ass) I also get him out daily hoping to encounter other dogs for training purposes.

Nothing has changed, no better, no worse. It's just that now my "psycho" is 55 pounds of solid muscle! Now that I have a firm understanding of the prong collar, hopefully I will begin to see some positive results. My dream is to be able to take him to a dog park to really run and play. Do you think with the genetically wired dog that I have this will ever be possible? Hope to hear back regarding the muzzle. Thanks for your great DVD.
