Hi.. My friends have got a german shepherd puppy and hes beautiful! He's 6 months old and very lovely.. but when I visit and sit down he dives up and tries to dive on me.. he also in play grabs my hand in his mouth which doesn't hurt but I obviously don't want this.. My friends tell him no and make him get down but what I want is to know the right way to stop this myself, as he's a big dog
Thank you
