awwww.....he's a puppy - that's what they DO. He should calm down but for now..try to enjoy him and not stress - they pick up on it and that could be the reason he acts out....which really isn't a good word because he's just being what he is...a very young dog not yet mature...
these guys are just like having REAL kids. Think of it like this - Kids are in diapers sometimes till 2 YEARS old - your puppy is only a puppy for a few months
I'd try taking him for walks everyday so he can get rid of some of that excess energy and be patient with him. They really do grow out of that biting stage...has he been neutered yet ??? That may or may not help with the Sir Humpalot stuff
