Yes, you have submissive peeing, as others have said. Dogs are like kids, for some a harsh look is discipline, and some need more. This dog needs a safe place, where nothing bad happens, like a crate. Drape a towel or blanket over it to make it dark but cleanable, and put it in a quiet corner. Give him his own chewies that stay in the crate.
An upholstered couch, once "blessed," will always smell like a pee spot to a dog. You may be able to stop the submissive peeing, but it might also help to recover or slipcover the cushions, or move it to another room at least temporarily. Also, use bitter
apple on the sunglasses.
Temporarily keep DH away from him, for example, get up early and let the dog out before your DH is about, then crate the dog until DH has left. He will likely appreciate having a safe place.
Then train as follows:
Pick a time/place when the dog is settled, maybe a room where there have been no issues (dogs remember the places things happen), or maybe outside. Pick a phrase like "relax, you're fine. " sit next to him, not a head on confrontation, and pet him a bit. See if you an get him to sit at your side. Now we have a positional cue, sitting at your side, a location cue, that place, and an audio cue "relax your fine" which all mean safety. So if you get this far without peeing, do it twice a day for four days. Then try it with your DH looking in. If it goes well, repeat once a day for four days. Then try it with your DH speaking. Then repeat the success twice a day for our days, ad so on. Then a little closer. Then with you between DH and the dog. Then with the dog between you. Then move to a different place. The longer the peeing went on, the longer and slower the recovery will be.
That's one approach, open to modification, free advice, worth every penny. But I also agree DH needs to take the dog to puppy classes or some kind of trainer. (Be prepared for the dog to pee in the car, it will be scary for the dog to be trapped in there with DH) That takes you out of the middle, and lets the trainer be the one to teach DH to be gentle with this dog. That's more likely to fix the dog/DH relationship long term, which is the real goal. Scared dogs can lead to fear biting, so addressing the issue is important.
