Having a dog that can't be alone at times with the kids won't work for me, I got to be able to trust him. It seems to be a dominate thing but he dosen't seem to want to hurt them just not respect them.
It is not a dominant thing; it is a puppy thing. He is
playing. True, this is not appropriate behavior with humans, but dogs are not born with this knowledge. He needs to be taught that.
Boxers are supose to be good with kids thats why we got one, but this guy is tough. I am mostly woried when he is no longer 20 pounds and is 70 pounds.
ALL PUPPIES BITE, regardless of the breed. Teach your pup bite inhibition and monitor him around the kids until he's learned some manners. Right now he is just a baby, you really can't expect him to be perfect without any guidance. You have to think, he has only been alive for
three months and nearly 2 of those months he was with his mom and littermates, eliminating wherever he pleased, competing for food, and rough-housing with the other puppies. He doesn't know that those things are no longer acceptable, and he shouldn't be left unsupervised
at all until he's completely house broken and can be trusted not to chew things or play too rough with the kids. The more you work with him the sooner you'll see results. Contrarily, the more he gets away with bad behavior, the harder it will be to break him of bad habits. And by "get away with" I mean that the behavior must be
prevented, not punished.
Have the kids participate in training. This will help build his respect for them so he sees them as leaders instead of playmates. VERY IMPORTANT: Make sure he gets plenty of daily exercise, mental stimulation (several small training sessions, a new interactive toy, a new activity, visiting a new person/place, etc.), and that he has plenty of safe bones and chew-toys to keep his mouth occupied. You will still need to supervise him around your children for the next few months. Once he gets his adult teeth in around 6 months old, his teeth won't be so sharp and painful (woohoo! appicon). But it is VERY important that he learns bite inhibition before this happens, because once the puppy teeth are gone it is near impossible to make any progress with bite inhibition training. However he is with biting/mouthing at that age is likely how he will always be.

Another tip -- I think that it is important for every dog (ESPECIALLY dogs that are going to be around children) to be accustomed to being handled, or "manhandled", if you will. You have to start doing this when your puppy is young, and you need to do it often. When you're relaxing with the pup and he is calm, give him a massage. Rub his ears, belly, legs, paws, etc. Touch his face and his tail, take a look inside his mouth, examine his toes and in between his paws, etc. Don't try to do these things when he's in a playful mood -- he'll be more reactive then -- but as long as he's being calm you can try a little bit more with him each day. If you do this he will be more comfortable and cooperative in the future during routine inspections, ear cleanings, nail trimming, brushing teeth, vet visits, bathing, grooming, etc. He will also be less reactive to pokes and prods from young children. While you're touching him you can talk to him softly, keeping him in that calm state and giving him praise for cooperating.
