Bite Bite Bite? No, no, no!
Chomp chomp chomp? Yes, yes, yes!
Don't, don't, don't bite your friends!
Don't, don't, don't bite your friends!

If the dog jumps up and starts biting, knee it in the chest/stomach to make it stop. This does not hurt him, but teaches him dicipline. After using this tecnique, the dog should stop jumping and biting.
If the dog is biting you when you are sitting, the dog probably wants to play. Playing will most likely lead to biting. When she bites you, shout "ow!" and take the dogs snout in your hands and tell it "no!". Then get up and walk away. This will teach your dog that if she wants to play, she needs to play gently, espacially if you have children.
Choke collars will only make the dog afraid of you and collars, choke or regular. They can also cause damage to the neck area of the dog, especially puppies. Do NOT use chokers unless it is recommended by a veteranarian!
When the dog can play with you gently, reward him with treats. He will realize that playing nice pays well.

Yes, I agree with the others. Choke collars are a no no with puppies, and I believe they shouldn't be used at all.

Boxers are awesome dogs, they are highly trainable and have a strong urge to please you. However, if not trained, they can easily become uncontrollable with their size and strength. Better start continuous training now because the older he will get the harder it will be to control him.

I agree with Karen, go to your local library and get some dog training books. I believe positive training (no punishments, using your dog's natural sense to please you) works best, instead of negative training (punishing physically or verbally when something wrong is done).
Both can work, but they both can be done wrong. There are plenty of internet sources you can find.

Boxers need plenty of EXERCISE! I'm sure you know this by now. They're are an obedient breed and they pick things up easily. However, they remain very puppy like and continue to have a short attention span. Use lots and lots of treats and keep training sessions short. It'll take some time but with training boxers make great pets. (My boxer is pictured in my sig at 6 months old. He's now 2 years )

Good luck!

I personally believe this method is cruel. Kneeing an animal in the chest certainly DOES hurt, and that is why the stop jumping. It doesn't teach discipline. It teaches that they will be hurt if they jump on you. I don't think you want to hurt your dog.

Simply turning around when your dog jumps on you, ignoring him in every way, should make the jumping subside and stop altogether. The reason he jumps is he wants attention! He will learn he only gets attention if he is calm and doesn't jump.

One thing not mentioned here is that the crate should never be used as punishment. The crate should be the dogs safe haven.
All the other advice given is great. I grew up with choke collars on our dogs, but I never use them on my two. Ever. I don't know why. I'm not against them, I just don't use them. But as others said, they should be used properly.
