I believe the dog is smart enough to know that the anger was directed at you, and he doesnt want to get in trouble by being around it.
I wont get into having a fight and throwing things- whether its a child or a dog, this behavior is a form of verbal abuse and people shouldl control their tempers. ( thats all I will say..)
As far as your dog, you need to make a effort of assurance. Trust has been broken for now. Start by when the dog appears fearful at you, do the dog " ignore". This is a slow calm glance away. In dog language you told the dog " I am not focusing on you, and accept your presence. Also when you glance at the dog, keep calm quiet, assuring eyes, but glance away SLOWLY . Try sitting on the floor with the dog in the room. I would not use the bedroom at this point as that is where the conflict took place. Maybe give little treats like your dog likes- like little pieces of hotdog or pieces of cookies. Hand it near you, but dont force the issue. Also do not reach over the dogs head. This blocks the dogs sight for a second not allowing the dog to see your calm quiet eyes.
Above all- keep the arguements of this explosive nature out of the house for now. The dog saw a side of both you he didnt know existed... This is going to take time. In other words- the dog now thinks if you are around- something is going to go flying across the room. Whoever was yelling when the crash occured, the dog thinks is the one that did it.
Femka- if the voices get raised, even watching a football game, she leaves the room. There were lots of fights were she came from. She is not cowering but it obviously upsets her.
