He sounds just like most puppies - hyper, chewers, going nonstop. I usually start to obedience train them as soon as they are done with imprinting and so forth at 12 -14 weeks but you can do some training earlier with the come, sit, stay, watch me type things to get him started off right and for only a minute or two a few times a day. Early and consistent training is so important to build the kind of working team you'll want to become.
Once he's gotten more control of his impulses, you can train him to go to a spot of your choice - say his bed or a rug - and stay there when the doorbell rings or your approach the front door and that will prevent door-darting but it takes a dog that has control of his impulses, repeated training and primed to want to stay there for the reward of praise, pride and treats he will get and which he's learned over time are all more satisfying than darting out the door. Once your dog has learned to work for your pride in him and how much he enjoys feeling that, plus the praise and treats as secondary benefits, he will stay where you train him to stay during open-door sessions and comings and goings even though it is very hard for little dogs.
