Cooter, Nice young pup. You are about a month or so away from puppy school age. So for now it might just be getting used to your environment and the pup taking charge of what you offer up. You can always just scoop him up and crate him. Use the "quiet" command, might be better than just NO as the pup will hear that enough as it gets older. You can also alpha roll him and hold him down and stare into his eyes until he takes his focus from you. That means he gave up. You win. His mom would grab him by the muzzle and lay on him or even utter a low growl, letting him know he is not in charge. Nothing too forceful now. He is just starting to develop his own personality but you still need to be regarded as the final say. Just basic stuff now. Try getting him on a leash and working with him to walk at your side. This will get his focus on other things. Short sessions and then back in the crate.
