My dog, a former show dog in the agility competition circuit was trained by positive reinforcement and negative reinforcement was never used.
Embarrassment at having an accident during potty training was enough for him to learn what he needed to do and this embarrassment is what we end up fighting against because a show dog needs confidence.
Also, his safe place is a place he has all to his own (his den) and the only time he is bothered if he is in there is if he needs to go to the vet or other such events that we have to move him.
We never had chewing issues or other bad behavioral issues with any of our dogs, although this one that I talk about above loves to squirrel his way out of our hotel rooms and go exploring - once he made it to the indoor pool and had a splash of a time.
Edit - @hustlertwo - I’m not going to demand anything but if you do decide to rewrite the scene, I do suggest using a positive reinforcement regime with the dog - reinforce with a reward for waiting until being outside as an example. I dunno, I’d be happy to talk over the scene with you if you want but each dog is an individual, so you know what would be best for the dog in your story.
