Whats your experience with a dog like this? Whats your experience with this breed?! You have a very large puppy. Teaching him to grab appropriate things is what you need to do. Teaching him to be calm in the house but crazy yet still respectful outside. I suggest you go read puppy threads regarding bite inhibition for sure.
The more people I meet and talk to,the more I love my dogs and their intelligence.
