I am not going to try to respond to David, but in response to Chip, this is a different set of dynamics, than the other thread.
I too would kick the dog's butt off the bed. If you don't have any issues, there is no problem with the dog on the bed. If you do have issues, time to go back to your NILIF with this dog, and start from scratch. Nothing, he gets nothing he does not work for.
Yes, definitely rule out medical, and I would cut out those bully stick. They are expensive and gross. I wouldn't want them around children, sorry, but these kind of treats often have issues with salmonella, etc. And these are the parts we humans don't eat for a reason. It also is a VERY high value treat, and your dog has given a strong indication that he cannot be trusted with a VERY high value treat with children around.
I would also get a trainer/behaviorist, and start working with this dog. The new puppy takes a lot of training/socialization, but your adult boy has given you the heads up that he is still a work in progress.
