Ok so here you go.
First of all, Don't give up on the NO BITE , push him away and ignored him. Do not grab him to take him to an other room just gently but firmly push him away. Same if he attack your other dog. A firm NO, and if needed, separated then by grabbing the other dog or gently/firmly pushing the puppy away.
Repetition is the key
Some dog are more submission and some more dominant. Your puppy is obviously on the dominant side so here is a few thing you should do to help establish your dominance:
Do not over baby the dog.Any attention given to the dog, including petting should be given when the you decides attention is to be given (absolutely No Petting when the dog nudges or paws you or your hand. This would be letting the dog decide and reinforcing, in his mind, that he is higher on the scale than you are.) *
Start teaching basic obedience command.A simple obedience command such as “Sit” should be given before any pleasurable interaction with the dog.
Games of fetch or play with toys must be Started and Ended by YOU.No tug-of-war , as this is a game of power and you may lose the game giving the dog a reinforcement (in the dog's mind) of top dog.
Feedings must be at a scheduled time no free feeding for now.
Do not let the dog go through any doorways first. Or up or down the stairs first.
When you have left the house or the room, even for a minute and come back in the room, ignore the dog for a few minutes.
You should be the one who greets newcomers first.
If a dog is laying in your path, do not walk around the dog, either make the dog move or step over the dog.
For now, the dogs should not sleep in your bed.
A daily walk is always the best way to established your dominance...
Good luck with the puppy, hope that will help.
