My dog has never growled, lunged or even aggressively bitten me. I don't worry about him biting anyone in our family. I do keep him on a leash though around small children because his prey drive is a little nuts. I don't want him tackling them and accidentally hurting them, I don't worry about him biting them in an aggressive way though. I don't have kids myself so training him around the actions and noises small kids make has been pretty close to none.
