Our Newfie Murphy had the same problem. He was incredibly mouthy. They do eventually grow out of it, and by 9 months they seem much better. One thing I did that helped was to keep his pen around, and as soon as the mouthing started, picked him up put him in the pen and ignored him for a few minutes. I made it seem like we were doing something really great without him, and he didn't like being left out. When he came out a few minutes later he was better, I kept repeating that, and he definitely got the message. Also, my breeder told me when he is nipping to pinch their ears, like another dog would do to them. It did usually get him to stop. Hope this helps.
