I've had two newfies and its definately part of the process of exploration! I got a great tip to deter the mouthiness if it was too much and that was to grab the chin and put your thumb on the toungue fairly firmly when they mouthed too much. Although its a good method to deter (as they hate having their toungue disabled lol) I would also encourage you to teach your dog the right pressure to hold your hand in its mouth as its an inherant trait for newfies to grab water rescue victums (been swimming with your dog?) and tow them into shore by arm or hand.
I found that when Shumba or Mambo used too much pressure - I would squeal a bit and sure enough there would be an apologetic lick to say oops ! Mambo was a quick learner and now - no probs.
