When i am home alone my german shephard wont calm down.(please read the whole post before you answer)?

be very firm wiht him, tell him NO every time that he dose that, eve though it may hurt you, hold his head to the ground and tell him NO, let him no that you only cuddel when you want to. He probably thinkts that you are like his equal right now. running is good but he is a puppy i don't think that you can ever get all of his energy out! Good Luck!
