Getting to this thread a little late. I am on my 4th weim to this date having lived with them the past 25 years. Your pup looks like a blue. They are another level of energy in my experience. Maybe even a little neurotic at times. Weims will try to run the show in most cases. They are an alert dog that always feel responsible for the house and family. They don't respond well to verbal reprimand in my experience. They are however extremely easy to train. Your dog seems to be food driven. That makes training even easier. The basics of come, sit, down, and most of all drop. As mentioned above, he does not eat until given "ok". He does not ever go out a door first. Get the rib bones after a few weeks of consistency. Lay them on the ground. After you ok him, go to drop. Repeat until it becomes boring. When it comes to a physical correction. I will not ever strike a dog. A quick snout clamp with the word "out" usually works. I had a rescue weim growl at my young daughter once upon a time. He went on his back very swiftly and held there for a few seconds. Never ever had an issue since. I would exercise the hell out of him and work obedience a minimum of 30m a day. That should ease his mind and help ya both. Feel free to PM if I can help anymore. Weims are a special breed in my opinion. They take time to learn but they are worth it.
