It's great that you are trying to get some good information and help with your dog. You will find some really great information on this board, but it won't be sugar coated, it helps to have a thick skin - ok, enough said.
1. I would take a look at the Q&A's section (again) and read everything that you can on dominate dogs for starters.
2. Also, Ed has some good tapes about basic, beginning puppy OB, I think they are worth the $$ for the tapes.
3. You need to get the proper equipment, leash, collars (prong, etc) and learn how to use them.
4. Structure your routine with your dog and don't let him run free in your house without a drag line.
5. Work on proper socialization skills with him. You can start by using your boyfriend. (i.e. have him meet you in your driveway, you tell your dog to sit or down and then after a couple of seconds, you have your boyfriend feed him slices of hot dogs, etc. Then you have him do it in your yard, your kitchen, your house, down the block, at the supermarket, while you are at the dry cleaners, etc). Once you do that, you said in an earlier post that you always have at least 2 other people at your house, have them do the same thing as well. Now, since your dog already is showing signs of rank and dominance, I would be very careful because you don't want anyone to get bit, right? Be smart about it, but be careful.
6. You don't have to teach your dog to be protective of you or to only listen to you or become terrortorial. All you have to do to work on the bonding issues will come via OB, long walks, grooming and OB OB OB OB OB & more OB.
7. Just think, if you are having a hard time now, what is going to happen when those hormones start to kick in at 1 1/2 yrs. Also, all of the right stuff and wrong stuff has already been learned, taught, reinforced to him, so you are going to have to essentially treat him like he is a new dog and you just got him today - Day #1. I'm talking major doggy boot camp, he gets away with "ZILCH" you have to be firm, fair, and know when to give praise (physical/verbal). He makes no decisions whatsoever, you tell him when and were to eat, pee, sleep, play, etc.
8. I would be calling the vet to neuter him right now.
I believe all dogs are "projects" and they will try to get away with as much as they can, regardless of breed, sex or age, they all are manipulators. You can learn quite a bit from here and read & reread the articles, I think your chances are slim with him and it may be to late, but try your best, locate a good trainor and get him into a good program, but do not attempt or encourage any protective behavior with him. Give yourself a timeline and stick to it and after that, either give him up to someone who has more experience, or back to the breeder or put him down, be responsible. You have to realize that maybe this isn't the breed for you, or maybe you got the "ALPHA" of the litter. Don't give up, but don't candy coat or make excuses for him either. You didn't mention it, but get that outside kennel up ASAP.
Good luck & train smart,
Brandon
